[Kernel-packages] [Bug 1705748] Re: Samsung SSD 960 EVO 500GB refused to change power state

[Kai-Heng Feng]

SRU: https://lists.ubuntu.com/archives/kernel-
team/2018-January/089222.html

** Description changed:

+ === SRU Justification ===
+ [Impact]
+ A user reported his NVMe went out to lunch after S3.
+ 
+ [Fix]
+ Disable APST for this particular NVMe + Motherboard setup.
+ 
+ [Test]
+ User confirmed this quirk works for his system.
+ 
+ [Regression Potential]
+ Very Low. This applies to a specific device setup, also user can
+ override this quirk by "nvme_core.force_apst=1".
+ 
+ === Original Bug Report ===
  Originally thought my issue was same as this:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184
  but requested to report as separate bug
  
  System becomes unusable at seemingly random times but especially after
  resume from suspend due to disk 'disappearing' becoming inaccessible,
  with hundreds of I/O errors logged.
  
  After viewing the above bug report yesterday as a quick temporary fix I added 
kernel param, updated grub, etc with:
  GRUB_CMDLINE_LINUX_DEFAULT="nvme_core.default_ps_max_latency_us=0"
  
  System appears to have been stable for the last day, but is presumably
  using more power than it should.

Print the function address associated with the restore_r2() error to
make it easier to debug the problem.

Also clarify the wording a bit.

Before:

  module_64: patch_foo: Expect noop after relocate, got 3c82

After:

  module_64: patch_foo: Expected nop after call, got 7c630034 at
netdev_has_upper_dev+0x54/0xb0 [patch_foo]

Note: This patch is optional, it improves the debugging message.

[Kernel-packages] [Bug 1741992] [2/3] powerpc/modules: Don't try to restore r2 after a sibling call

[bugproxy]

--- Comment on attachment From kamale...@in.ibm.com 2018-01-09 01:40 
EDT---


When attempting to load a livepatch module, I got the following error:

  module_64: patch_module: Expect noop after relocate, got 3c82

The error was triggered by the following code in
unregister_netdevice_queue():

  14c:   00 00 00 48 b   14c 
 14c: R_PPC64_REL24  net_set_todo
  150:   00 00 82 3c addis   r4,r2,0

GCC didn't insert a nop after the branch to net_set_todo() because it's
a sibling call, so it never returns.  The nop isn't needed after the
branch in that case.

[Kernel-packages] [Bug 1741992] [1/3] powerpc/modules: Add REL24 relocation support of livepatch symbols

[bugproxy]

--- Comment on attachment From kamale...@in.ibm.com 2018-01-09 01:39 
EDT---


Livepatch re-uses module loader function apply_relocate_add() to write
relocations, instead of managing them by arch-dependent
klp_write_module_reloc() function.

apply_relocate_add() doesn't understand livepatch symbols (marked with
SHN_LIVEPATCH symbol section index) and assumes them to be local
symbols by default for R_PPC64_REL24 relocation type. It fails with an
error, when trying to calculate offset with local_entry_offset():

  module_64: kpatch_meminfo: REL24 -1152921504897399800 out of range!

Whereas livepatch symbols are essentially SHN_UNDEF, should be called
via stub used for global calls. This issue can be fixed by teaching
apply_relocate_add() to handle both SHN_UNDEF/SHN_LIVEPATCH symbols
via the same stub. This patch extends SHN_UNDEF code to handle
livepatch symbols too.

[Kernel-packages] [Bug 1741636] Re: Lenovo E560 die after Ubuntu 17.10 was installed

[Po-Hsu Lin]

Hello,

from the login screen issue you mentioned it sounds like a video driver issue.
Can you try to boot 16.04.1 LTS version to see if it works?

BTW, there is a bug in 17.10 (bug 1734147), your model is not on the
list but it's still worthy to take a note here.

  Hi Guys

  My Lenovo E560 die after some days of Ubuntu 17.10 has been installed.

  Sometimes I make login successfully but the login screen go back
  again.

  Sometimes I was forced to remove the laptop battery and put it again
  to get the computer to live again.

  Yesterday the login screen appear after few minutes without touch the
  keyboard or mouse and the screen torn off. Until now the laptop
  doesn't make boot, and it seems like the motherboard or cpu is die.

  I love Ubuntu but I think I lost my new laptop.

  Back to MS Windows? No!!!

  Panasonic Toughbook CF-30 (specifically CF-30K, also known as "CF30",

  Pointing and clicking (also tapping to click) works, but scrolling

Bug description:
  kpatch is a Linux dynamic kernel patching infrastructure which allows
  you to patch a running kernel without rebooting or restarting any
  processes. It enables sysadmins to apply critical security patches to
  the kernel immediately, without having to wait for long-running tasks
  to complete, for users to log off, or for scheduled reboot windows. It
  gives more control over uptime without sacrificing security or
  stability.

  kpatch is upstream hosted at 
  https://github.com/dynup/kpatch
  https://github.com/dynup/kpatch/releases

  Add support for livepatch infrastructure on ppc64le
  https://github.com/dynup/kpatch/pull/650

Title:
  Ubuntu freezes after suspend [ Lenovo T460s / Ubuntu 17.10 ]

Status in linux package in Ubuntu:
  Expired

Bug description:
  Closing the lid will suspend Ubuntu (17.10). After opening the lid the
  screen is either black (no backlight) or the lock screen is shown but
  the system is freezed. There is no further reaction from the system (I
  can't switch via Ctrl+Alt+F1..9. Just MagicKey+RB would reboot the
  system.

  I have appended my syslog from the suspend to the freeze. What other
  information could I provide?

[Kernel-packages] [Bug 1741934] Re: Kernel panic with xenial 4.4 stack (4.4.0-108.131, Candidate kernels for PTI fix)

[Taihsiang Ho]

A quick test for comment #19 looks good. The test result for Dell Vostro
5468 (CID 201606-22340) looks good
https://certification.canonical.com/hardware/201606-22340/submission/126230/

** Description changed:

  [Description]
  
  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same kernel
  panic shown in many different pre-installed Ubuntu images of different
  platform.
  
  So far these platform are known to reproduce this issue:
  
+ CID 201606-22340 (Dell Vostro 5468)
  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)
  
  [Steps to Reproduce]
  
  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.
  
  [Expected Result]
  
  No kernel panic message.
  
  [Actual Result]
  
  Kernel panic message as:

Cannot add that information because if I load kernel 4.13.0-24 I do not
have wifi and cannot log to this page. I have to do it with the previous
kernel  4.13.0-22 to place the bug

[Kernel-packages] [Bug 1726519] Re: Unable to handle kernel NULL pointer dereference at isci_task_abort_task

[Abelardo]

I have same issue. I hoped it was fixed on kernel 4.14.12 (since it is
the LTS kernel which patches spectre & meltdown); but it is also broken.

I also do get the error mentioned about.

Can this please be fixed for good? please?

[Kernel-packages] [Bug 1741992] [NEW] kpatch - Add livepatch hook support for ppc64le

[bugproxy]

Public bug reported:

kpatch is a Linux dynamic kernel patching infrastructure which allows
you to patch a running kernel without rebooting or restarting any
processes. It enables sysadmins to apply critical security patches to
the kernel immediately, without having to wait for long-running tasks to
complete, for users to log off, or for scheduled reboot windows. It
gives more control over uptime without sacrificing security or
stability.

kpatch is upstream hosted at

Bug description:
  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  ---

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!

Objet: [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel 

This is what I typically do when I compile a custom kernel on a new 
machine. You need development tools like git, gcc, gmake etc. but I 
guess many distros have most of that stuff already installed. I did not 
try these so there might be typos and something could be missing. 

These steps should help to recover a system where there is some Linux 
distro (not necessarily Ubuntu). 

1. Get the latest kernel tree

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git 
$ cd linux 

2. Checkout the v4.15-rc7 branch

$ git checkout -b spi-nor-recover v4.15-rc7

3. Save and apply the patch from https://goo.gl/xUKJFR (this is the 
same patch that is linked in the bug description) 

$ git am 0001-Clear-both-SR-and-CR-explicitly-and-also-add-debug-m.patch

4. Configure the kernel so that it takes only those modules that you 
have currently loaded 

$ make localmodconfig

5. You may need to enable MTD subsystem, SPI-NOR and the intel-spi 
driver so run 

$ make nconfig

Then select following from the config

Device Drivers ---> 
<*> Memory Technology Device (MTD) support ---> 
 SPI-NOR device support ---> 
 Intel PCH/PCU SPI flash platform driver 

Then press F9 and to save .config and exit nconfig.

6. Build the kernel image and modules

$ make -j8

7. Once it is properly built without any errors you can install it 
along with the modules 

$ sudo make modules_install 
$ sudo make install 

Once the custom kernel is installed, you can reboot to this new kernel 
and it should clear the CMP bit from the serial flash status register. 
It logs something like below to your dmesg: 

[ 19.724288] intel-spi intel-spi: wrote SSFSTS_CTL=0x0045020c 
[ 19.724301] intel-spi intel-spi: wrote FDATA(0)=00 00 
[ 19.724304] intel-spi intel-spi: wrote SSFSTS_CTL=0x0041360c 
[ 19.736538] intel-spi intel-spi: wrote SSFSTS_CTL=0x0040520c 
[ 19.736542] intel-spi intel-spi: Both SR/CR cleared 

Then when you reboot, the BIOS should be able to save settings again and 
you can boot back to your distro kernel. 

After this you can remove the custom kernel from /boot and modules from 
/lib/modules.

[Kernel-packages] [Bug 1722109] Re: iwlwifi regression in artful - intermittent total packet loss

[Bryan Petty]

Following up on my last report here, it seems like my issues have been
resolved in the last week or two here. I didn't keep track close enough
to figure out if it was a recent package/kernel update or not, but just
wanted to note that I'm no longer seeing this intermittent packet loss
anymore over wifi.

  Unfortunately, I don't have a good reproduction recipe, as the fault
  doesn't seem to occur immediately after boot, nor is it an absolute
  failure of connectivity - from a user perspective, it feels like, for
  example, the website you are using is responding exceptionally slowly.
  It is only on testing multiple remote sites, and finding that
  rebooting into an earlier kernel fixes the issue, that it is apparent
  that it's a local OS problem.

[Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

[Eric]

Thanks Mika, Farid, Logan, Daniele, Anthony, Vivien, Volkmar, Fabio, Kevh, 
Danny!
But with my configuration I can not install the kernel without errors.
I put back to read my previous message #485

Acer ES1-111-C1ZM
System Bios version V1.13
InsydeH20 Setup Utility

Ubuntu 16.04.03LTS / 32bits / Openbox
kernel 4.4.0.104


I did as indicated #294 the manipulation ukuu to the kernel 4.14.09.
And I have install 4.15.0-041500rc6 with errors (i686?).
I suppose i can't do the installation manipulation of 4.15 if I do not have an 
amd64 system.

After a lot of tests with other older kernels, without progress, deadlock.
Always not boot device choice, new hard drive not detected, etc..
Does anyone have an idea to work around this problem?


That's why I'm asking for some help. Thanks again.

  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  ---

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very 

[Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

[Mika Westerberg]

This is what I typically do when I compile a custom kernel on a new
machine. You need development tools like git, gcc, gmake etc. but I
guess many distros have most of that stuff already installed. I did not
try these so there might be typos and something could be missing.

These steps should help to recover a system where there is some Linux
distro (not necessarily Ubuntu).

  1. Get the latest kernel tree

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ cd linux

  2. Checkout the v4.15-rc7 branch

$ git checkout -b spi-nor-recover v4.15-rc7

  3. Save and apply the patch from https://goo.gl/xUKJFR (this is the
 same patch that is linked in the bug description)

$ git am 0001-Clear-both-SR-and-CR-explicitly-and-also-add-debug-m.patch

  4. Configure the kernel so that it takes only those modules that you
 have currently loaded 

$ make localmodconfig 

  5. You may need to enable MTD subsystem, SPI-NOR and the intel-spi 
 driver so run

$ make nconfig

 Then select following from the config

   Device Drivers  --->
 <*> Memory Technology Device (MTD) support  --->
  SPI-NOR device support  --->
Intel PCH/PCU SPI flash platform driver

 Then press F9 and to save .config and exit nconfig.

  6. Build the kernel image and modules
  
$ make -j8   
   
  7. Once it is properly built without any errors you can install it
 along with the modules

$ sudo make modules_install
$ sudo make install

Once the custom kernel is installed, you can reboot to this new kernel
and it should clear the CMP bit from the serial flash status register.
It logs something like below to your dmesg:

[   19.724288] intel-spi intel-spi: wrote SSFSTS_CTL=0x0045020c
[   19.724301] intel-spi intel-spi: wrote FDATA(0)=00 00
[   19.724304] intel-spi intel-spi: wrote SSFSTS_CTL=0x0041360c
[   19.736538] intel-spi intel-spi: wrote SSFSTS_CTL=0x0040520c
[   19.736542] intel-spi intel-spi: Both SR/CR cleared

Then when you reboot, the BIOS should be able to save settings again and
you can boot back to your distro kernel.

After this you can remove the custom kernel from /boot and modules from
/lib/modules.

Re: [Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

[Eric]

Thanks Mika, 
But with my configuration I can not install the kernel without errors. 
I put back to read my previous message # 485 

Acer ES1-111-C1ZM 
System Bios version V1.13 
InsydeH20 Setup Utility 

Ubuntu 16.04.03LTS / 32bits / Openbox 
kernel 4.4.0.104 



I did as indicated #294 the manipulation ukuu to the kernel 4.14.09. 
And I have install 4.15.0-041500rc6 with errors (i686?). 
I suppose i can't do the installation manipulation of 4.15 if I do not have an 
amd64 system. 

After a lot of tests with other older kernels, without progress, deadlock. 
Always not boot device choice, new hard drive not detected, etc.. 
Does anyone have an idea to work around this problem? 



That's why I'm asking for some help. Thanks again.

You can build your own kernel so that you first apply the patch in the 
bug description. Then boot to that custom kernel which should clear the 
CMP bit from the serial flash and your BIOS should be functional again. 
Let me know if you want instructions how to patch and build a custom 
kernel.

Symptoms:

* USB Boot impossible 
* EFI entries read-only.

Fix: The issue was fixed in kernel version 4.13.0-21 by configuring 
the kernel so it is not compiled with Intel SPI support. But previous 
affected machines still suffered from a broken BIOS. 

Repair: If you still can boot into Ubuntu, you can recover your BIOS 
with the following steps: 

1. Boot into Ubuntu 
2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
 
3. Install the downloaded package: 
$ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
 
4. Make sure the kernel is installed without any error. Once installed, reboot. 
5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode. 
6. Reboot and go to BIOS settings to confirm your BIOS has been recovered. 
7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS. 
8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6. 

After your BIOS is fixed, the kernel packages you just installed are 
no longer needed, you can remove it by running 'sudo dpkg -r linux- 
image-4.15.0-041500rc6-generic'. 

The patch used to build the linux v4.15 kernel in step 8 can be found 
at https://goo.gl/xUKJFR.

Test Case: Fix has been verified by our HWE team on affected hardware.

Regression Potential: Minimal, it's unlikely anyone is actually doing 
anything which requires this driver.

Bug description:
  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  ---

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  ---

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!

[Kernel-packages] [Bug 1733662] Re: System hang with Linux kernel 4.13, not with 4.10

[Rod Smith]

You're right. (I've got too many kernels installed on that system!) When
I tested again, it got through eight runs without problems, beyond the
"error -19" message. Here's the uname information, just to be sure:

$ uname -a

Bug description:
  In doing Ubuntu 17.10 regression testing, we've encountered one
  computer (boldore, a Cisco UCS C240 M4 [VIC]), that hangs about one in
  four times when running our cpu_offlining test. This test attempts to
  take all the CPU cores offline except one, then brings them back
  online again. This test ran successfully on boldore with previous
  releases, but with 17.10, the system sometimes (about one in four
  runs) hangs. Reverting to Ubuntu 16.04.3, I found no problems; but
  when I upgraded the 16.04.3 installation to linux-
  image-4.13.0-16-generic, the problem appeared again, so I'm confident
  this is a problem with the kernel. I'm attaching two files, dmesg-
  output-4.10.txt and dmesg-output-4.13.txt, which show the dmesg output
  that appears when running the cpu_offlining test with 4.10.0-38 and
  4.13.0-16 kernels, respectively; the system hung on the 4.13 run. (I
  was running "dmesg -w" in a second SSH login; the files are cut-and-
  pasted from that.)

  I initiated this bug report from an Ubuntu 16.04.3 installation
  running a 4.10 kernel; but as I said, this applies to the 4.13 kernel.

  Fix Committed
Status in linux-hwe-edge source package in Xenial:
  Fix Released
Status in linux-oem source package in Xenial:

Status in linux source package in Artful:

Bug description:
  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  ---

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  ---

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!

[Kernel-packages] [Bug 1733662] Re: System hang with Linux kernel 4.13, not with 4.10

[Joseph Salisbury]

The uname looks like you may still be running the kernel from comment
#37.  The test kernel with the revert should have a name like:

linux-image-4.13.0-21-generic_4.13.0-21.24~lp1733662Revert_amd64

The string "Revert" should be in the uname output.

Bug description:
  In doing Ubuntu 17.10 regression testing, we've encountered one
  computer (boldore, a Cisco UCS C240 M4 [VIC]), that hangs about one in
  four times when running our cpu_offlining test. This test attempts to
  take all the CPU cores offline except one, then brings them back
  online again. This test ran successfully on boldore with previous
  releases, but with 17.10, the system sometimes (about one in four
  runs) hangs. Reverting to Ubuntu 16.04.3, I found no problems; but
  when I upgraded the 16.04.3 installation to linux-
  image-4.13.0-16-generic, the problem appeared again, so I'm confident
  this is a problem with the kernel. I'm attaching two files, dmesg-
  output-4.10.txt and dmesg-output-4.13.txt, which show the dmesg output
  that appears when running the cpu_offlining test with 4.10.0-38 and
  4.13.0-16 kernels, respectively; the system hung on the 4.13 run. (I
  was running "dmesg -w" in a second SSH login; the files are cut-and-
  pasted from that.)

  I initiated this bug report from an Ubuntu 16.04.3 installation
  running a 4.10 kernel; but as I said, this applies to the 4.13 kernel.

[Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

[Daniele Bianchin]

If I don't have Ubuntu installed how can I recover BIOS?
Ubuntu bricked my BIOS when I was trying it with a live USB.
I have another Linux os in to my pc, can I recover BIOS from there?

Bug description:
  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  ---

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  ---

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!

[Kernel-packages] [Bug 1741934] Re: Kernel panic with xenial 4.4 stack (4.4.0-108.131, Candidate kernels for PTI fix)

[Joseph Salisbury]

Upstream 4.4.110 commit 20cbe9a3aa2e was back ported to Xenial as commit
f8365429a3dc1.  However, the backport failed to remove a kfree(), which
the original patch did:

@@ -381,7 +415,6 @@ static void release_ds_buffer(int cpu)
return;

per_cpu(cpu_hw_events, cpu).ds = NULL;
-   kfree(ds);
 }

I'm building a Xenial test kernel now with the kfree removed.  I will
post it shortly.

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel panic shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel panic message.

  [Actual Result]

  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel panic shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel panic message.

  [Actual Result]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel panic shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel panic message.

  [Actual Result]

  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel panic shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel panic message.

  [Actual Result]

  Kernel panic message as:

Bug description:
  [Description]

  When using PPA https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/pti/ to fetch the candidate kernels for
  CVE-2017-5754, CVE-2017-5715 and CVE-2017-5753. There is the same
  kernel panic shown in many different pre-installed Ubuntu images of
  different platform.

  So far these platform are known to reproduce this issue:

  CID 201606-22349 (Dell Inspiron 7560)
  CID 201606-22365 (Dell Inspiron 5767)

  [Steps to Reproduce]

  1. Install the target pre-installed image (Xenial 4.4-based stack) for the 
platform.
  2. Fetch the kernel 4.4.0-108.131 from this PPA 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/pti/
  3. Update the system by "sudo apt-get dist-upgrade"
  4. After the system update, reboot it.
  5. Check the syslog after the system is ready to use again.

  [Expected Result]

  No kernel panic message.

  [Actual Result]

  Kernel panic message as:

Bug description:
  In doing Ubuntu 17.10 regression testing, we've encountered one
  computer (boldore, a Cisco UCS C240 M4 [VIC]), that hangs about one in
  four times when running our cpu_offlining test. This test attempts to
  take all the CPU cores offline except one, then brings them back
  online again. This test ran successfully on boldore with previous
  releases, but with 17.10, the system sometimes (about one in four
  runs) hangs. Reverting to Ubuntu 16.04.3, I found no problems; but
  when I upgraded the 16.04.3 installation to linux-
  image-4.13.0-16-generic, the problem appeared again, so I'm confident

  that appears when running the cpu_offlining test with 4.10.0-38 and
  4.13.0-16 kernels, respectively; the system hung on the 4.13 run. (I
  was running "dmesg -w" in a second SSH login; the files are cut-and-
  pasted from that.)

  I initiated this bug report from an Ubuntu 16.04.3 installation
  running a 4.10 kernel; but as I said, this applies to the 4.13 kernel.

[Kernel-packages] [Bug 1734147] Re: corrupted BIOS due to Intel SPI bug in kernel

[Eric]

Eric #485
I have a question almost the same:
please Anthony Wong, is-it possible to build new ISOs of Ubuntu 
16.04/32bits-i686, 
to get a kernel that corrects the bios?

Bug description:
  An update to linux kernel on Ubuntu 17.10 that enabled the Intel SPI
  drivers results in a serial flash that is read only in Intel Broadwell
  and Haswell machines with serial flashes with SPI_NOR_HAS_LOCK set.

  Symptoms:
   * BIOS settings cannot be saved
   * USB Boot impossible
   * EFI entries read-only.

  Fix: The issue was fixed in kernel version 4.13.0-21 by configuring
  the kernel so it is not compiled with Intel SPI support. But previous
  affected machines still suffered from a broken BIOS.

  Repair: If you still can boot into Ubuntu, you can recover your BIOS
  with the following steps:

  1. Boot into Ubuntu
  2. Download 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  3. Install the downloaded package:
    $ sudo dpkg -i 
linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
  4. Make sure the kernel is installed without any error. Once installed, 
reboot.
  5. At grub, choose the newly installed kernel. You can choose the "recovery" 
mode.
  6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
  7. In case your BIOS is not recovered, reboot to the new kernel, then reboot 
*once again* to the new kernel, do not enter BIOS settings before the reboot. 
After the second reboot, check BIOS.
  8. If your BIOS issue remains, download another kernel from 
http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+clear+debug_amd64.deb,
 and use dpkg to install it, then repeat steps 4 to 6.

  After your BIOS is fixed, the kernel packages you just installed are
  no longer needed, you can remove it by running 'sudo dpkg -r linux-
  image-4.15.0-041500rc6-generic'.

  The patch used to build the linux v4.15 kernel in step 8 can be found
  at https://goo.gl/xUKJFR.

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!
