  xfstest fails with sanity checks on seek operations

  # uname -a
  Linux ltc-tuleta12 4.10.0-21-generic #23~16.04.1-Ubuntu SMP Tue May 2 
12:54:57 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux

  Steps to reproduce:
  
  1. Create a loop device with xfs filesystem
  2. git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git; cd 
xfstests-dev
  3. make
  4. Create a local.config for running with created loop device
  5. Run xfstests-dev test  : ./check tests/generic/285 or ./check 
tests/generic/436

  The test 285 fails with following
  ...
  ...
  07. Test file with unwritten extents, only have dirty pages
  07.01 SEEK_HOLE expected 0 or 45056, got 0.   succ

  08.04 SEEK_DATA expected 40960 or 40960, got -1.  FAIL

  The test 436 fails with 
  ...
  ...
  14. Test file with unwritten extents, small hole after pagevec dirty pages
  14.01 SEEK_HOLE expected 917504 or 4194304, got 3670016.  FAIL

  commit 5375023ae1266553a7baa0845e82917d8803f48c
  Author: Jan Kara 
  Date:   Thu May 18 16:36:22 2017 -0700

  xfs: Fix missed holes in SEEK_HOLE implementation
  XFS SEEK_HOLE implementation could miss a hole in an unwritten extent as
  can be seen by the following command:
  
  xfs_io -c "falloc 0 256k" -c "pwrite 0 56k" -c "pwrite 128k 8k"
 -c "seek -h 0" file
  wrote 57344/57344 bytes at offset 0
  56 KiB, 14 ops; 0. sec (49.312 MiB/sec and 12623.9856 ops/sec)
  wrote 8192/8192 bytes at offset 131072
  8 KiB, 2 ops; 0. sec (70.383 MiB/sec and 18018.0180 ops/sec)
  Whence  Result
  HOLE139264
  
  Where we can see that hole at offset 56k was just ignored by SEEK_HOLE
  implementation. The bug is in xfs_find_get_desired_pgoff() which does
  not properly detect the case when pages are not contiguous.
  
  Fix the problem by properly detecting when found page has larger offset
  than expected.

  The above commit fixes the generic/436 test, but generic/285 still FAILS.

  The generic/285 failure is reproducible on most P8/P9 systems.

Title:
  text VTs are unavailable on desktop after upgrade to Ubuntu 17.10

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Artful:
  In Progress

Bug description:
  After upgrading my laptop to Ubuntu 17.10, I am unable to access
  gettys on any of the text-mode VTs on my system.

  gdm3 is running on VT1, my user session is running on VT2.  I can
  switch between these.  If I switch to VT3, I know that the VT switch
  has happened in the kernel because the X cursor disappears; but the
  display retains the output of my X session, and the text console with
  getty never appears.

  Switching back to VT2 works fine.

  The same problem occurs with either Wayland or X.

  My laptop is docked with an external monitor, which could be a factor.
  (I also notice that during boot, plymouth is only rendered on the
  internal monitor, not the external monitor; this may be related).  I
  have not yet tested whether this problem is reproducible if I undock.

  The system is booting with vt.handoff=7, which I believe is still the
  default in Ubuntu 17.10.

Title:
  [patch included]Slow speed and dropped connections with Realtek
  RTL8192CU-based wifi

Status in linux package in Ubuntu:
  Triaged

Bug description:
  EDIT(other user): Some one fixed it in github, still works in at least in 
linux 4.4-4.11
  https://github.com/pvaret/rtl8192cu-fixes
  EDIT:

  I am using a D-Link DWA-131 USB wlan adapter to connect to my private wlan.
  The adapter works fine under Windows and I have no problems connecting to my 
wlan with other devices (e.g. my laptop running Linux Mint).
  However, the adapter, which is based on the Realtek rtl8192cu chipset, won't 
work correctly on any current Ubuntu machine (in my case Kubuntu 15.10 64bit):

  As also showcased by a myriad of other bug reports (most of which have 
expired by now), wlan-adapters based on the Realtek rtl8192cu chipset exhibit 
very slow connection speeds and frequently dropped connections with current 
Linux kernels.
  I have noticed this originally in Linux Mint 17 running kernel 3.19.x, in 
Kubuntu 15.10 up to 4.2.0.35 and can confirm that it is still present in a live 
session of Xenial Xerus (16.04).
  I have tried commonly mentioned "fixes" such as deactivating hardware 
encryption without success.

  The drivers available on the Realtek homepage are apparently intended
  for older kernels and won't install.

  There is, however, a fixed driver available via github 
(https://github.com/pvaret/rtl8192cu-fixes).
  I have followed the instructions found there and finally my wlan-adapter is 
working correctly.
  Apparently the issues caused by the broken driver in the linux kernels might 
be connected to power management.

  I am posting this bug here in the hope that some developer finally manages to 
incorporate the (obviously available) fixes found in the github-drivers into 
the drivers already included in the kernel.

[Kernel-packages] [Bug 1697450] Re: Gnome Shell hangs at startup

[Daniel van Vugt]

OK, we're going to need to analyse the hung gnome-shell process. Please
try to do this:

1. Install openssh-server:
   sudo apt install openssh-server
2. Using a second machine, log into the offending machine via SSH:
   ssh @ 
   where  is your username, and  is either hostname or the 
machine's IP address.
3. Reproduce the hang.
4. From your ssh login, run:
   killall -TRAP -u $USER gnome-shell
5. Look in /var/crash for a newly created file, something like 
'_usr_bin_gnome-shell.1000.crash'
6. Upload the crash file using this command or similar:
   ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash
7. Tell use the new bug ID that was created.

  I'm not sure how to debug this further, but I had similar issues with the 
installer from Zesty as well (see

  With Artful, at least it gets past the splash screen but then it hangs.

  Note that the system is currently running Yakkety with no issue.

[Kernel-packages] [Bug 405294] Re: A2DP Bluetooth audio skips terribly ["Skipping NNN us (= MMM bytes) in audio stream"]

[Daniel van Vugt]

> FYI this problem sits high on the Pulseaudio bug list, but...

For Ubuntu users yes this is the "hottest" bug in the pulseaudio
package:

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bugs?orderby=-heat=0

However, upstream have been mostly silent on this bug since January
2015:

https://bugs.freedesktop.org/show_bug.cgi?id=88827

Any solution here will likely come from upstream so if you continue to
experience this bug in Ubuntu 17.10 (and soon 18.04) please comment on
the above link.

[Kernel-packages] [Bug 1723680] Re: GPU Hang in Xorg rcs0 drm/i915

[Aun]

I am unable to get useful debug info from the kernel for a bug report.
It hangs at a black screen and will not respond to any of the magic
sysreq commands.  I tried the intel drm-tip too and same result.  Fully
hung, can't ssh in, no console, nothing, completely wedged.  Don't want
to send bug report without details.

I'm building some tags between working and not working and will try a
bisect after I narrow it down.  linus v4.10 tag build works fine.

Any suggestions?

[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

[George Mathioudakis]

** Description changed:

- I recently bought the following laptop: 
+ I recently bought the following laptop:
  Asus VivoBook X542UQ-DM148T - 15.6" (i7-7500U/8GB/256GB/GT 940MX 2GB)
  
  It came pre-installed with Win10 and I did a fresh install of Ubuntu
  16.04 LTS. The screen was flickering for some reason and installing
  Ubuntu 17.04 fixed the issue.
  
  The real problem is that when I'm booting the laptop, the following
  error is being shown on my screen:
  
  [   12.866073] pcieport :00:1c.5: can't find device of ID00e5
  [   12.898481] pcieport :00:1c.5: AER: Multiple Corrected error received: 
id=00e5
  [   12.898488] pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, id=00e5(Receiver ID)
  [   12.898491] pcieport :00:1c.5:   device [8086:9d15] error 
status/mask=2041/2000
  [   12.898492] pcieport :00:1c.5:[ 0] Receiver Error (First)
  [   12.898493] pcieport :00:1c.5:[ 6] Bad TLP
  
  I know that this error can be hid with one of the following kernel boot 
arguments:
  pci=nomsi / pci=noaer / pcie_aspm=off / pci=nommconf.
  
  The weird thing is that the above output is only being shown when the
  laptop is on AC Power (charging). When the laptop is not connected to AC
  (battery-mode), it has performance issues (slow boot and slow
  application launching). I was trying all day long to fix the problem. I
  removed everything that had to do with power-saving, reinstalled, re-
- tweaked for performance but had no luck. While diagnosing, I had the
- idea to benchmark the "M2 SATA-3 SSD" that my laptop had. The results
- are:
+ tweaked for performance, tried different kernels but had no luck. While
+ diagnosing, I had the idea to benchmark the "M2 SATA-3 SSD" that my
+ laptop had. The results are:
  
  * On AC Power: 522MB/s (READ) | 416MB/s (WRITE)
  * On Battery Power: 32MB/s (READ) | 31MB/s (WRITE)
  
  This explains everyting. That's why I'm having a slow boot and slow
  application launching!
  
  Commands "lspci" and "dmesg" say that the error comes from the following 
device:
  00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port 
#6 (rev f1)
  
  I will attach lspci and dmesg output on a tar.gz file.

Title:
  PCIe BUS Error causing really slow laptop performance

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I recently bought the following laptop: 
  Asus VivoBook X542UQ-DM148T - 15.6" (i7-7500U/8GB/256GB/GT 940MX 2GB)

  It came pre-installed with Win10 and I did a fresh install of Ubuntu
  16.04 LTS. The screen was flickering for some reason and installing
  Ubuntu 17.04 fixed the issue.

  The real problem is that when I'm booting the laptop, the following
  error is being shown on my screen:

  [   12.866073] pcieport :00:1c.5: can't find device of ID00e5
  [   12.898481] pcieport :00:1c.5: AER: Multiple Corrected error received: 
id=00e5
  [   12.898488] pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, id=00e5(Receiver ID)
  [   12.898491] pcieport :00:1c.5:   device [8086:9d15] error 
status/mask=2041/2000
  [   12.898492] pcieport :00:1c.5:[ 0] Receiver Error (First)
  [   12.898493] pcieport :00:1c.5:[ 6] Bad TLP

  I know that this error can be hid with one of the following kernel boot 
arguments:
  pci=nomsi / pci=noaer / pcie_aspm=off / pci=nommconf.

  The weird thing is that the above output is only being shown when the
  laptop is on AC Power (charging). When the laptop is not connected to
  AC (battery-mode), it has performance issues (slow boot and slow
  application launching). I was trying all day long to fix the problem.
  I removed everything that had to do with power-saving, reinstalled,
  re-tweaked for performance but had no luck. While diagnosing, I had
  the idea to benchmark the "M2 SATA-3 SSD" that my laptop had. The
  results are:

  * On AC Power: 522MB/s (READ) | 416MB/s (WRITE)
  * On Battery Power: 32MB/s (READ) | 31MB/s (WRITE)

  This explains everyting. That's why I'm having a slow boot and slow
  application launching!

  Commands "lspci" and "dmesg" say that the error comes from the following 
device:
  00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port 
#6 (rev f1)

  I will attach lspci and dmesg output on a tar.gz file.

[Kernel-packages] [Bug 1572698] Re: [patch included]Slow speed and dropped connections with Realtek RTL8192CU-based wifi

[Patrick Then]

I'm currently not using the adapter since I've moved to a new apartment where 
it's easily possible to connect via cable to the lan.
I don't remember there being any errors though.
Seriously guys, the solution is available on github, I linked it over one year 
ago, all the necessary information should be there.

  [patch included]Slow speed and dropped connections with Realtek
  RTL8192CU-based wifi

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  EDIT(other user): Some one fixed it in github, still works in at least in 
linux 4.4-4.11
  https://github.com/pvaret/rtl8192cu-fixes
  EDIT:

  I am using a D-Link DWA-131 USB wlan adapter to connect to my private wlan.
  The adapter works fine under Windows and I have no problems connecting to my 
wlan with other devices (e.g. my laptop running Linux Mint).
  However, the adapter, which is based on the Realtek rtl8192cu chipset, won't 
work correctly on any current Ubuntu machine (in my case Kubuntu 15.10 64bit):

  As also showcased by a myriad of other bug reports (most of which have 
expired by now), wlan-adapters based on the Realtek rtl8192cu chipset exhibit 
very slow connection speeds and frequently dropped connections with current 
Linux kernels.
  I have noticed this originally in Linux Mint 17 running kernel 3.19.x, in 
Kubuntu 15.10 up to 4.2.0.35 and can confirm that it is still present in a live 
session of Xenial Xerus (16.04).
  I have tried commonly mentioned "fixes" such as deactivating hardware 
encryption without success.

  The drivers available on the Realtek homepage are apparently intended
  for older kernels and won't install.

  There is, however, a fixed driver available via github 
(https://github.com/pvaret/rtl8192cu-fixes).
  I have followed the instructions found there and finally my wlan-adapter is 
working correctly.
  Apparently the issues caused by the broken driver in the linux kernels might 
be connected to power management.

  I am posting this bug here in the hope that some developer finally manages to 
incorporate the (obviously available) fixes found in the github-drivers into 
the drivers already included in the kernel.

Title:
  text VTs are unavailable on desktop after upgrade to Ubuntu 17.10

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Artful:
  In Progress

Bug description:
  After upgrading my laptop to Ubuntu 17.10, I am unable to access
  gettys on any of the text-mode VTs on my system.

  gdm3 is running on VT1, my user session is running on VT2.  I can
  switch between these.  If I switch to VT3, I know that the VT switch
  has happened in the kernel because the X cursor disappears; but the
  display retains the output of my X session, and the text console with
  getty never appears.

  Switching back to VT2 works fine.

  The same problem occurs with either Wayland or X.

  My laptop is docked with an external monitor, which could be a factor.
  (I also notice that during boot, plymouth is only rendered on the
  internal monitor, not the external monitor; this may be related).  I
  have not yet tested whether this problem is reproducible if I undock.

  The system is booting with vt.handoff=7, which I believe is still the
  default in Ubuntu 17.10.

[Kernel-packages] [Bug 1715552] Re: VMWare does not start

[Daniel]

This occurs also with Kubuntu 17.10 RTM and VMware Workstation Pro 
12.5.7-5813279.
I remember that on 17.04 it didn't occur.
I used to install the same version of VMWare Workstation in Kubuntu 17.04, 
running inside a virtual machine (just for testing purposes).

[Kernel-packages] [Bug 1690085] Re: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks

[AS]

I can confirm the issue with a week 33 Ryzen 1700 on Asus Prime B350 Plus.
I had segfaults with my previous 1700 (week 22 iirc). No more segfaults with 
the week 33 CPU but still random crashes on (long time) idle.

  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Here is kern.log entry when happening :

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  
  Thanks

[Kernel-packages] [Bug 1724639] Re: Graphics problem - 80% of the Left hand side of screen solid black

[Eduard]

@kaihengfeng;

I have tried both kernels you proposed, and can confirm what has been stated in 
the opensuse-Forum:
Both Kernels 4.11 and 4.12 SEEM to be working and show no graphic glitches.

So the first idea would be that something happend within the Kernel transition 
from 4.12 to 4.13, , but not too easy. 
Trying to open differnet Applications with 4.12 shows that there is already 
something fishy going on with the graphics, e.g. LibreOffice will not start 
with Kernel 4.12 and I believe it must have to do with the graphics.

This is in accordance with the errors / logs / exceptions posted in the
opensuse bug-report.

So for Computers / Laptops / Netbooks using the Intel Mobile 945
Chipsets and Ubuntu 17.10, I would personally recommend the 4.11 Kernel,
for I found it to be most stable and all applications I have tested so
far do work.

I can help with logs and dmesg if needed, please just tell me what logs
you need.



For everyone who has this error, I will show you a workaround so you can still 
use your computer even after the update to 17.10.
The workaround consists of installing kernel 4.11 and using it.

Enter Grub (which is the startup manager) by holding down the shift key while 
booting.
If you have Grub showing up on every boot (e.g. if you have a multi OS and also 
have Win 7/8/10) installed, even better. 
Now select Ubuntu ... enhanced options and then select starting up with the  
4.10 Kernel (which still should be installed if you have updated from 17.04). 
If the option to start up with the 4.10 kernel is not available, select 
recovery mode (which should also work fine, but you have to work with a low 
resolution then)

In the 4.10 Ubuntu (recovery mode) open your browser and go to this directory: 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11/

under "Build for i386 succeeded" download these 3 files:

linux-headers-4.11.0-041100_4.11.0-041100.201705041534_all.deb
linux-headers-4.11.0-041100-generic_4.11.0-041100.201705041534_i386.deb
linux-image-4.11.0-041100-generic_4.11.0-041100.201705041534_i386.deb

After the download, put those 3 Files in a new, seperate folder, and
open the directory with the terminal (right click on the folder --> open
in Terminal).

In the Terminal post:

sudo dpkg -i *.deb

Press enter and wait. The 4.11 Kernel will be installed, it takes a while.
After that, you can reboot your computer and in Grub in the enhanced options 
you can now start your computer with the 4.11 generic kernel, which works fine 
for me.

If you want Ubuntu to start up everytime with the 4.11 Kernel, you can
use the "Grub Customzier" for that. Here is how you install the grub
customizer:

http://ubuntuhandbook.org/index.php/2014/04/install-grub-customizer-
ubuntu-1404/


Let's hope that someone in this Linux world can make the Intel Mobile Graphics 
card work again in a de-bugged 4.13 kernel =)

Cheers and Kudos everyone !

Title:
  system hangs during boot when using a USB Keyboard

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My USB Keyboard consistently turns off as soon as the boot process
  gets past the GRUB menu. The system then hangs - indefinitely, unless
  I plug the keyboard in again.

  This behaviour was present in Beta 2 and manifests itself in the
  official release - freshly installed - both in default and recovery
  mode.

  Dmesg reports:
  watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [swapper/0:0]
  watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [swapper/3:0]
  (Obviously, the number of seconds depends on the time it takes me to plug the 
keyboard in again). 

  And well before those lines comes:
  pci :00:12.1: OHCI: BIOS handoff failed (BIOS bug?) 0184

  When I watch the boot messages roll off the screen, I see the system indeed 
get halted on a message about OHCI:
  ohci-pci :00:12.1: irq 16, io mem 0xfe02d000

  I doubt this is actually a BIOS bug because I have been using this
  same board without a glitch for six or seven years now.

[Kernel-packages] [Bug 1725948] [NEW] system hangs during boot when using a USB Keyboard

[Jay S.]

Public bug reported:

My USB Keyboard consistently turns off as soon as the boot process gets
past the GRUB menu. The system then hangs - indefinitely, unless I plug
the keyboard in again.

This behaviour was present in Beta 2 and manifests itself in the
official release - freshly installed - both in default and recovery
mode.

Dmesg reports:
watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [swapper/0:0]
watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [swapper/3:0]
(Obviously, the number of seconds depends on the time it takes me to plug the 
keyboard in again). 

And well before those lines comes:
pci :00:12.1: OHCI: BIOS handoff failed (BIOS bug?) 0184

When I watch the boot messages roll off the screen, I see the system indeed get 
halted on a message about OHCI:
ohci-pci :00:12.1: irq 16, io mem 0xfe02d000

I doubt this is actually a BIOS bug because I have been using this same
board without a glitch for six or seven years now.

[Kernel-packages] [Bug 1724639] Re: Graphics problem - 80% of the Left hand side of screen solid black

[Eduard]

I can confirm the bug too.
After the Xubuntu update from 17.04 to 17.10, the intel mobile graphics is 
broken.

Moreover, the issue seems to be a little bigger.
The bug here is the same one as bug #1720703 , so Mods please merge the two 
bugs.
(https://bugs.launchpad.net/ubuntu-mate/+bug/1720703)
It seems to have nothing to do with the Ubuntu distro, as is is present in 
Ubuntu Mate,
Ubuntu, Lubuntu und Xubuntu, all Versions 17.10 -- > so this indicates that it 
is Kernel 4.13
related.


And it seems to affect other distros as well.
The bug also affects OpenSuse, with Kernel 4.13:
https://bugzilla.opensuse.org/show_bug.cgi?id=1058870

So there seems to be something wrong with Kernel 4.13 with the Intel
Graphics 945.

In the openSUSE Bug Report, users state that Kernels 4.11 and 4.12 are
still working.

I will test that right now and report back.

Thank you Community for all the efforts.

  The problem also appears with proposed 4.4.0-97.

  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to

Title:
  No graphical boot with 4.4.0-96 and NVIDIA GeForce 840M

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My computer (using XUbuntu 16.04) boots and works normally with kernel
  4.4.0-92 but upgrading to 4.4.0-96 prevents lightdm from starting. In
  fact, the GPU detection service fails.

  The problem also appears with proposed 4.4.0-97.

  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to
  wifi with this kernel).

  GPU is GEForce 840M with proprietary nvidia 475 drivers (purged and
  reinstalled once).

Title:
  No graphical boot with 4.4.0-96 and NVIDIA GeForce 840M

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My computer (using XUbuntu 16.04) boots and works normally with kernel
  4.4.0-92 but upgrading to 4.4.0-96 prevents lightdm from starting. In
  fact, the GPU detection service fails.

  The problem also appears with proposed 4.4.0-97.

  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to
  wifi with this kernel).

  GPU is GEForce 840M with proprietary nvidia 475 drivers (purged and
  reinstalled once).

Title:
  No graphical boot with 4.4.0-96 and NVIDIA GeForce 840M

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My computer (using XUbuntu 16.04) boots and works normally with kernel
  4.4.0-92 but upgrading to 4.4.0-96 prevents lightdm from starting. In
  fact, the GPU detection service fails.

  The problem also appears with proposed 4.4.0-97.

  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to
  wifi with this kernel).

  GPU is GEForce 840M with proprietary nvidia 475 drivers (purged and
  reinstalled once).

[Kernel-packages] [Bug 1722269] Re: No graphical boot with 4.4.0-96 and NVIDIA GeForce 840M

[YS1]

apport information

** Description changed:

  My computer (using XUbuntu 16.04) boots and works normally with kernel
  4.4.0-92 but upgrading to 4.4.0-96 prevents lightdm from starting. In
  fact, the GPU detection service fails.
  
  The problem also appears with proposed 4.4.0-97.
  
  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to wifi
  with this kernel).
  
  GPU is GEForce 840M with proprietary nvidia 475 drivers (purged and
  reinstalled once).

  text VTs are unavailable on desktop after upgrade to Ubuntu 17.10

Status in linux package in Ubuntu:

Status in linux source package in Artful:

Bug description:
  After upgrading my laptop to Ubuntu 17.10, I am unable to access
  gettys on any of the text-mode VTs on my system.

  gdm3 is running on VT1, my user session is running on VT2.  I can
  switch between these.  If I switch to VT3, I know that the VT switch
  has happened in the kernel because the X cursor disappears; but the
  display retains the output of my X session, and the text console with
  getty never appears.

  Switching back to VT2 works fine.

  The same problem occurs with either Wayland or X.

  My laptop is docked with an external monitor, which could be a factor.
  (I also notice that during boot, plymouth is only rendered on the
  internal monitor, not the external monitor; this may be related).  I
  have not yet tested whether this problem is reproducible if I undock.

  The system is booting with vt.handoff=7, which I believe is still the
  default in Ubuntu 17.10.

[Kernel-packages] [Bug 405294] Re: A2DP Bluetooth audio skips terribly ["Skipping NNN us (= MMM bytes) in audio stream"]

[GPratique]

@Konrad: thanks for taking the time to explain the situation details.

However I have to report that when switching to Windows 10, on the exact
same PC (just a drive swap), Bluetooth performs flawlessly with both my
speakers (JBL Flip 3 and UE Miniboom).

This suggests that it is not a hardware problem but a software one.

FYI this problem sits high on the Pulseaudio bug list, but...

  As I upgraded to the Karmic alpha, bluetooth audio (via a2dp) stopped

  My headphones are detected and configured by pulse, but the audio

  happens with whatever player I use) the audio continues until it's
  caught up.

[Kernel-packages] [Bug 1690085] Re: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks

[Franck Charras]

Ryzen CPUs manufactured before week 24 of this year were known to have
issues (especially the segfault issue). It was officially fixed for all
ryzen manufactured after week 30. All my ryzen are pre-24 CPUs and they
all have this silent crash issue. Does it also happen with the post week
30 ryzen ? (@tgui what is yours ?)

  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  
  Thanks

Can you try to boot under 4.4.0-92?
Probably a cpu-manager/bbswitch issue instead of a kernel one.

Title:
  No graphical boot with 4.4.0-96 and NVIDIA GeForce 840M

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My computer (using XUbuntu 16.04) boots and works normally with kernel
  4.4.0-92 but upgrading to 4.4.0-96 prevents lightdm from starting. In
  fact, the GPU detection service fails.

  The problem also appears with proposed 4.4.0-97.

  I tested with mainline kernel 4.13. It boots to lightdm but it is
  difficult to exactly tell what happens as some modules for my hardware
  were not found/compiled/installed (as a result, I cannot connect to
  wifi with this kernel).

  GPU is GEForce 840M with proprietary nvidia 475 drivers (purged and
  reinstalled once).
