** Description changed:

My machine is solid state.
I updated the intel graphics driver
I update a few days ago via ubuntu udpater

- There is a subtle clicking noise coming near from the usb port. The machine
is solid state and the ubuntu is running from the sd card The noise happnes
with usb live boot too.
+ There is a subtle clicking noise coming from the left speaker.
+
The mint 17 usb makes the noise too and then warns me that that the graphics
gpu will not be used and then the clicking stops.
-
- Lubuntu installed on top of ubuntu still makes the noise.
- Lubuntu live usb does NOT make the noise.
+ ubuntu makes the noise.
+ Lubuntu 16.04 does not make the noise, until I installed pulseaudio.
+ before that, it would make the noise if I installed and ran, metacity and or
audacity.
+
Windows 10 does not make the noise.

- I suspect compiz, but ultimately I think it is a kernal problem.
+
+ I saw some comments on askubuntu.com
+ I think it is a conflict with the nouveau driver not loading properly. This
is why the soundcard and graphics affect the problem
+ Usually, this bug is caused by alsa automute (removed) and power-save for the
sound card. I was unable to set the settings so that the file changes would
"stick" the kernel keeps overwriting the files even if I mark them as nobody
can change.

This bug has been reported on ubuntu forums and ask ubuntu and no responses.
- I will be switching to Lubuntu in a few days unless I hear back from you. I
am technical and willing to help.
+ This bug still exists for Lubuntu 16.04 with the latest kernel 4.6-rc6
+ The bios has be downgraded to 1.09 from 1.12 since it did not fix the problem.

[Kernel-packages] [Bug 1493386] Re: IN CAR: SIM2 calls cann not be routed via car audio

Are there any news on this bug? How about the implementation progress on
supporting 2 SIM cards used with bluetooth?

Bug description:
  STEPS:
  Requirements: Aquaris E4.5 with 2 SIMs, 2nd phone, a car with blue tooth 
phone support (Seat Alhambra 2012 in my case)

  1. Connect the Aquaris to the car (with two SIM cards, car kid shows the 
provider of the 2nd SIM card in the display)
  2. From the second device call the number of SIM1
  3. Phone & car sound rings and call can be taken

  4. From the second device call the number of SIM2
  5. Phone does ring but car kit not.

  6. Call 2nd phone from Aquaris connected to the car with SIM1 (via the phone 
directly or using the car kit)
  7. Normal behaviour with in car phone & audio system

  8. Call 2nd phone from Aquaris connected to car with SIM2 (only possible 
dialling from the phone)
  9. No sound on the phone, no microphone support

  EXPECTED:
  I expect that calls from SIM2 can be taken and performed as from SIM1

  ACTUAL:
  SIM2 seems not to work when phone is connected to blue tooth of car whereby 
SIM1 works flawlessly

Bug description:
  After OTA-9 I started having trouble with my bluetooth connection to the car 
hands-free system (no sound, and incoming calls no longer displayed the 
number), so I have reset both the car and the phone connections (eg. forgot the 
devices).
  Now I can't even pair the phone with the car's system. 
  The car finds the phone, and then asks me to enter the code "" to pair 
the device, but after a few moments, it just says the connection failed and 
asks me to try again. Which fails again.

  It was working fine just before the update.

  Any logs I should post to help debug?

  PS - The car is a 2015 Honda Civic Tourer, if that matters.

[Kernel-packages] [Bug 1578141] Re: Predictable interface names partially broken with igb driver

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.6 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

  Predictable interface names partially broken with igb driver

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Note: I'm not sure whether this is really a kernel bug or something
  within systemd/udev, please advise how to further debug.

  On a system with two GE ports, instead of getting named eno1 and eno2,
  I am getting eno1 and renameN. Where N starts at 3 and increases by 2
  on every iteration of doing "rmmod igb;modprobe igb". The
  corresponding lines in dmesg look like this:

  [2.748429] igb :07:00.0: added PHC on eth0
  [2.748431] igb :07:00.0: Intel(R) Gigabit Ethernet Network Connection

  [2.748505] igb :07:00.0: eth0: PBA No: 106100-000
  [2.748506] igb :07:00.0: Using MSI-X interrupts. 8 rx queue(s), 8 tx 
queue(s)
  [2.802555] igb :07:00.1: added PHC on eth1
  [2.802557] igb :07:00.1: Intel(R) Gigabit Ethernet Network Connection

  [2.803618] igb :07:00.0 eno1: renamed from eth0
  [2.833208] igb :07:00.1 rename3: renamed from eth1

  What is even worse: Sometimes the naming changes and the second
  interface ends up as eno1 while the first interface is named renameN
  with an even N. The bad thing about this version is that when it
  happens while the installer is running, the installer will setup
  "rename2" as the primary network interface, which works fine for the
  installation itself, but after installation is finished and the first
  boot of the installed system happens, that interface will be gone,
  leaving the system without network connectivity.

[Kernel-packages] [Bug 1328965] Re: 3.13.0-29 kernel includes backport of 3.14 16-bit app restrictions but not override method causing wine win9x to fail

The "/proc/sys/abi/ldt16" workaround was removed from the mainline Linux
kernel two years ago* so the method described in comment #17 is only
valid for older kernels.  "/proc/sys/abi/ldt16" will not be present in
recent or any future kernel versions.

For Ubuntu 15.10 or 16.04, the underlying problem with 16-bit apps
should have been resolved by other patches that came in the same
timeframe.  If that functionality itself isn't working, please file a
new bug report.

  Kernel 3.13.0-29 evidently contains a backport of the 3.14 kernel
  security workaround that disables 16-bit binaries from running.  This
  causes all wine Windows 95 and Windows 98 applications to fail.  The
  3.14 kernel also includes a feature to re-enable support for 16-bit
  binaries by providing the /proc/sys/abi/ldt16 interface.  This part of
  the kernel patch was evidently not backported, so this ability to
  override the 16-bit application prohibition is not available.

  For this reason, I cannot move forward to new kernel releases until
  this is fixed.

[Kernel-packages] [Bug 1577057] Re: zfs initrd script fails when rootdelay boot option is set

2016-05-04 Thread Sam VdE

Here are the test results:

- no datasets mounted when it breaks
- A delay of 1 second is not enough: breaks on first try
- Retested with 5 seconds delay: ok

- Retested with new zfs script: notok, again the pool is busy error.

I had a quick look at the script and I found the remaining problem: the
command ZFS_STDERR=$(zpool export "$ZFS_RPOOL" >/dev/null) will not
capture stderr messages. I adapted this to ZFS_STDERR=$(zpool export
"$ZFS_RPOOL" 2>&1  >/dev/null) and was able to boot correctly using
rootdelay=10. So I think that solves it.

Title:
  zfs initrd script fails when rootdelay boot option is set

Status in zfs-linux package in Ubuntu:
  Confirmed

Bug description:
  It looks like that, when booting off zfs (zfs holds /boot) with the
  rootdelay boot option set, the boot process fails in the initrd fase,
  asking to manually import the pool using zpool import -f -R / -N. I
  only had one system with that parameter set, which I seldom reboot.

  I did not find an upstream reference of this bug or behavior.

  The error is caused by the fact the pool is already imported: "zpool
  status" executed on the initramfs prompt will correctly list the pool
  and all devices online. To continue, one has to export the pool, re-
  import it and exit the initramfs prompt after which regular booting
  continues. Not exporting and reimporting it leaves the pool readonly
  leading to boot errors further down the road (systemd units failing).

  I noticed zfs_autoimport_disable is set to 1 in the initramfs
  environment, so looking at /usr/share/initramfs-tools/scripts/zfs this
  section might be the issue (zpool import succeeding, but $ZFS_HEALTH
  never returning with the correct status (I'm not a programmer but
  perhaps ZFS_HEALTH is a local variable in the zfs_test_import
  function)):

   delay=${ROOTDELAY:-0}

   if [ "$delay" -gt 0 ]
   then
    # Try to import the pool read-only.  If it does not import with
    # the ONLINE status, wait and try again.  The pool could be
    # DEGRADED because a drive is really missing, or it might just
    # be slow to be detected.
    zfs_test_import
    retry_nr=0
    while [ "$retry_nr" -lt "$delay" ] && [ "$ZFS_HEALTH" != "ONLINE" ]
    do
     [ "$quiet" != "y" ] && log_begin_msg "Retrying ZFS read-only import"
     /bin/sleep 1
     zfs_test_import
     retry_nr=$(( $retry_nr + 1 ))
     [ "$quiet" != "y" ] && log_end_msg
    done
    unset retry_nr
    unset ZFS_HEALTH
   fi
   unset delay

  
  Edit: to be clear: I removed the rootdelay parameter, regenerated the initrd, 
and was able to boot successfully afterwards.

[Kernel-packages] [Bug 1539158] Re: Unable to pair with in-car hands-free system after OTA-9 update

2016-05-04 Thread Konrad Zapałowicz

It seems that I know what is happening and why the pairing is denied. I
think that it is because the device when added to the internal data
structures is not yet fully initialized as the properties are gathered
asynchronously. In the same time the pin request is executed  that tries
to use the yet not valid device. As a consequence the pairing is denied
as the whole procedure is interrupted.

Now, just to confirm what is happening on the Ubuntu System Settings
side I would like to look at the Ubuntu System Settings log. You can
find somewhere in .cache/upstart/application [now I'm not sure] legacy
/ubuntu-system-settings.log It would be awesome if you could search for
it and paste here. Thanks in advance.

  After OTA-9 I started having trouble with my bluetooth connection to the car 
hands-free system (no sound, and incoming calls no longer displayed the 
number), so I have reset both the car and the phone connections (eg. forgot the 
devices).
  Now I can't even pair the phone with the car's system. 
  The car finds the phone, and then asks me to enter the code "" to pair 
the device, but after a few moments, it just says the connection failed and 
asks me to try again. Which fails again.

  It was working fine just before the update.

  Any logs I should post to help debug?

  PS - The car is a 2015 Honda Civic Tourer, if that matters.

[Kernel-packages] [Bug 1561830] Re: Hard disk writes fail in 16.04 daily on nForce 430

I built a Xenial test kernel with a revert of commit 64d513ac31.  The
test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1561830/

Can you test this kernel and see if it resolves this bug?

  Hard disk writes fail in 16.04 daily on nForce 430

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Xenial:

Bug description:
  I have an old PC I use for testing new operating systems.  It has
  previously had Ubuntu 15.10 installed and working.  The motherboard is
  an Asus M2NPV-VM, with Nvidia nForce 430 chipset and Nvidia GeForce
  6150 GPU.  I have installed an Nvidia GT220 card to use for more
  modern video support.

  When I attempt to install Ubuntu 16.04 beta (daily xenial-desktop-
  amd64.iso file downloaded 24/03/2016  18:17), it starts to write to
  the hard disk (Samsung HD103UJ), and after a short time the install
  got lots of disk write errors in kern.log.  After the errors, the disk
  was unable to be read either, with "fdisk -l /dev/sda" failing to read
  a sector, where it had worked before starting the install.  Unplugging
  the SATA cable to the drive and plugging it in again made the drive
  work again (on /dev/sdc), but another attempt to install failed with
  the same write errors.

  I noticed that the log had swap write errors also, so I rebooted the
  install DVD again, and this time did a "swapoff -a" command before
  attempting to install, but got the same errors again.  So I found my
  Ubuntu 15.10 install DVD and tried a new install from that, which
  worked just fine.

  On rebooting with my 16.04 daily DVD, I again did "swapoff -a" so that
  the DVD based system would run normally, then tried mounting the EXT4
  system partition I had just installed using the 15.10 install DVD.
  That worked, so I tried dd commands to do test writes to that
  partition.  The following commands worked:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=10k
dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=100k

  but when I did this command:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=1000k

  after a while errors started appearing in kern.log, just as with the
  attempts to install 16.04.

  It appears that with sustained write activity, the errors will start
  and then the drive will become unusable until it is unplugged and
  plugged in again.

  I have attached the kern.log and syslog files from the 15.10 install
  that worked, and the 16.04 install attempt that failed.  The first
  error message appears to be this:

  ata3: EH in SWNCQ mode,QC:qc_active 0x1FFF sactive 0x1FFF
  ata3: SWNCQ:qc_active 0x1 defer_bits 0x1FFE last_issue_tag 0x0
  dhfis 0x1 dmafis 0x0 sdbfis 0x0

  which leads me to suspect a problem with the handling of the SATA 
controller's interrupts.

[Kernel-packages] [Bug 1470250] Re: [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based Backups

@faulpeltz,

Yes, I did test a kernel with commit 6ad4874.  I tried this before
starting the bisect since it looked suspect.

I'm still testing dfbdac2e as well and will let it run for another 24
hours.

  This relates to the VSS "Windows Server Backup" process that kicks off at 
midnight on the host and finishes an hour and half later.   
  Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct 
kernel version we have.   We're currently running kernel version 
3.13.0-49-generic #83 on one system and 3.16.0-34-generic #37 on the other. -- 
We see the same errors on both.
  As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 
hyper-v system because of this.   We can stop the backup process and all is 
good, but we need nightly backups to image all of our VM's.   All the windows 
guests have no issues of course.   We also have some CentOS based guests 
running without issues from what we've seen.

  Problem Description
  ===
  ubuntu 14.04.4 installation on Firestone baremetal with "Guided - use entire 
disk and set up LVM" fails when ext3 is chosen as / file system. Below error 
message is displayed.

  
  ? [!!] Partition disks ?

  Steps to Reproduce
  =
  1. Start netboot installation on Firestone baremetal machine from

?? [!!] Partition disks ???
? ?
? The installer can guide you through partitioning a disk (using  ?
? different standard schemes) or, if you prefer, you can do it?
? manually. With guided partitioning you will still have a chance later   ?
? to review and customise the results.?
? ?
? If you choose guided partitioning for an entire disk, you will next ?
? be asked which disk should be used. ?
? ?
? Partitioning method:?
? ?
?  Guided - use entire partition, SCSI5 (0,0,0), partition #2 (sdk)   ?
?  Guided - use the largest continuous free space ?   ?
?  Guided - use entire disk and set up LVM?   ?

Bug description:
  I'm working on an Lubuntu 15 machine. It was chosen because it
  supports VIA C7-D processor and the VIA PM400 chipset without crashing
  (also see ). Lubuntu 15 uses the 4.2 kernel:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 15.10
Release:15.10
Codename:   wily

  And:

$ uname -a
Linux via 4.2.0-30-generic #36-Ubuntu SMP Fri Feb 26 00:57:19 UTC 2016 i686 
i686 i686 GNU/Linux

  When running a particular program (details below), it hangs in syscall
  248 and results in the following dmesg/syslog output. The process
  cannot be killed, the machine does not respond to a 'shutdown -r now',
  and the machine requires a hard reset.

  The process details is this is a failed self test for the upcoming

  $ ps -A | grep afalgtest

  And:

Bug description:
  Guys,

   I'm facing an issue here with both "ethtool" and "ip", while trying
  to manage black-listed by DPDK PCI VirtIO devices.

   You'll need an Ubuntu Xenial KVM guest, with 4 VirtIO vNIC cards, to
  run those tests

   PCI device example from inside a Xenial guest:

  ---
  # lspci | grep Ethernet
  00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:04.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:05.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:06.0 Ethernet controller: Red Hat, Inc Virtio network device
  ---

  Where "ens3" is the first / default interface, attached to Libvirt's
  "default" network. The "ens4" is reserved for "ethtool / ip" tests
  (attached to another Libvirt's network without IPs or DHCP), "ens5"
  will be "dpdk0" and "ens6" "dpdk1"...

  ---
   *** How it works?

   1- For example, try to enable multi-queue on DPDK's devices, boot
  your Xenial guest, and run:

   ethtool -L ens5 combined 4
   ethtool -L ens6 combined 4

   2- Install openvswitch-switch-dpdk configure DPDK and OVS and fire it
  up.

   https://help.ubuntu.com/16.04/serverguide/DPDK.html

   service openvswitch-switch stop
   service dpdk stop

   OVS DPDK Options (/etc/default/openvswitch-switch):

  --
  DPDK_OPTS='--dpdk -c 0x1 -n 4 --socket-mem 1024 --pci-blacklist 
:00:03.0,:00:04.0'
  --

   service dpdk start
   service openvswitch-switch start

   - Enable multi-queue on OVS+DPDK inside of the VM:

   ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=4
   ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0xff00

   * Multi-queue apparently works! ovs-vswitchd consumes more that 100%
  of CPU, meaning that it multi-queue is there...

   *** Where it fails?

   1- Reboot the VM and try to run ethtool again (or go straight to 2
  below):

   ethtool -L ens5 combined 4

   2- Try to fire up ens4:

   ip link set dev ens4 up

  
   # FAIL! Both commands hangs, consuming 100% of guest's CPU...

   So, it looks like a Linux fault, because it is "allowing" the DPDK
  VirtIO App (a user land App), to interfere with kernel devices in a
  strange way...

  Best,
  Thiago

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

2016-05-04 Thread Ethan

Kernel 4.4.8  solved my issues completely! I can plug any monitor before
or after boot using DP or HDMI. I also have multiple window managers
working flawlessly.

Title:
  Plugging HDMI screen in causes system hang

Status in linux package in Ubuntu:
  Fix Committed

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1470250] Re: [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based Backups

2016-05-04 Thread faulpeltz

@jsalisbury
We have 3.13.0-34.60 already running for about 22hours straight, no problems 
yet, as well as dfbdac2e, which also runs fine for now.
I'll just keep it running for a few days
Also, unfortunately, our result for 5e6cf71 might be invalid because the test 
machine ran out of disk space on the host because of excessive snapshot disks 
piling up. I had to add a delay of a couple of minutes after each backup to 
prevent this from happening, this caused basically the same error (kernel error 
message, readonly remount, disk i/o hang) as the real crash
So if things are stable with those two versions I will rerun 5e6cf71 and 
83215219 to make sure the result can be trusted
You already tested a kernel with 6ad4874 reverted, right? Are we sure this is 
not the culprit?

@emsi
We experienced that too, but weirdly trying to crash it by creating snapshots 
in a loop only caused one crash on one machine and wasnt reproducible any more

  Customers have reported running various versions of Ubuntu 14.04.2 LTS
  on Generation 2 Hyper-V Hosts.On a random Basis, the file system
  will be mounted Read-Only due to a "disk error" (which really isn't
  the case here).As a result, they must reboot the Ubuntu guest to
  get the file system to mount RW again.

  This relates to the VSS "Windows Server Backup" process that kicks off at 
midnight on the host and finishes an hour and half later.   
  Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct 
kernel version we have.   We're currently running kernel version 
3.13.0-49-generic #83 on one system and 3.16.0-34-generic #37 on the other. -- 
We see the same errors on both.
  As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 
hyper-v system because of this.   We can stop the backup process and all is 
good, but we need nightly backups to image all of our VM's.   All the windows 
guests have no issues of course.   We also have some CentOS based guests 
running without issues from what we've seen.

Title:
  Hard disk writes fail in 16.04 daily on nForce 430

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Xenial:
  Confirmed

Bug description:
  I have an old PC I use for testing new operating systems.  It has
  previously had Ubuntu 15.10 installed and working.  The motherboard is
  an Asus M2NPV-VM, with Nvidia nForce 430 chipset and Nvidia GeForce
  6150 GPU.  I have installed an Nvidia GT220 card to use for more
  modern video support.

  When I attempt to install Ubuntu 16.04 beta (daily xenial-desktop-
  amd64.iso file downloaded 24/03/2016  18:17), it starts to write to
  the hard disk (Samsung HD103UJ), and after a short time the install
  got lots of disk write errors in kern.log.  After the errors, the disk
  was unable to be read either, with "fdisk -l /dev/sda" failing to read
  a sector, where it had worked before starting the install.  Unplugging
  the SATA cable to the drive and plugging it in again made the drive
  work again (on /dev/sdc), but another attempt to install failed with
  the same write errors.

  I noticed that the log had swap write errors also, so I rebooted the
  install DVD again, and this time did a "swapoff -a" command before
  attempting to install, but got the same errors again.  So I found my
  Ubuntu 15.10 install DVD and tried a new install from that, which
  worked just fine.

  On rebooting with my 16.04 daily DVD, I again did "swapoff -a" so that
  the DVD based system would run normally, then tried mounting the EXT4
  system partition I had just installed using the 15.10 install DVD.
  That worked, so I tried dd commands to do test writes to that
  partition.  The following commands worked:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=10k
dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=100k

  but when I did this command:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=1000k

  after a while errors started appearing in kern.log, just as with the
  attempts to install 16.04.

  It appears that with sustained write activity, the errors will start
  and then the drive will become unusable until it is unplugged and
  plugged in again.

  I have attached the kern.log and syslog files from the 15.10 install
  that worked, and the 16.04 install attempt that failed.  The first
  error message appears to be this:

  ata3: EH in SWNCQ mode,QC:qc_active 0x1FFF sactive 0x1FFF
  ata3: SWNCQ:qc_active 0x1 defer_bits 0x1FFE last_issue_tag 0x0
  dhfis 0x1 dmafis 0x0 sdbfis 0x0

  which leads me to suspect a problem with the handling of the SATA 
controller's interrupts.

Bug description:
  Guys,

   I'm facing an issue here with both "ethtool" and "ip", while trying
  to manage black-listed by DPDK PCI VirtIO devices.

   You'll need an Ubuntu Xenial KVM guest, with 4 VirtIO vNIC cards, to
  run those tests

   PCI device example from inside a Xenial guest:

  ---
  # lspci | grep Ethernet
  00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:04.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:05.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:06.0 Ethernet controller: Red Hat, Inc Virtio network device
  ---

  Where "ens3" is the first / default interface, attached to Libvirt's
  "default" network. The "ens4" is reserved for "ethtool / ip" tests
  (attached to another Libvirt's network without IPs or DHCP), "ens5"
  will be "dpdk0" and "ens6" "dpdk1"...

  ---
   *** How it works?

   1- For example, try to enable multi-queue on DPDK's devices, boot
  your Xenial guest, and run:

   ethtool -L ens5 combined 4
   ethtool -L ens6 combined 4

   2- Install openvswitch-switch-dpdk configure DPDK and OVS and fire it
  up.

   https://help.ubuntu.com/16.04/serverguide/DPDK.html

   service openvswitch-switch stop
   service dpdk stop

   OVS DPDK Options (/etc/default/openvswitch-switch):

  --
  DPDK_OPTS='--dpdk -c 0x1 -n 4 --socket-mem 1024 --pci-blacklist 
:00:03.0,:00:04.0'
  --

   service dpdk start
   service openvswitch-switch start

   - Enable multi-queue on OVS+DPDK inside of the VM:

   ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=4
   ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0xff00

   * Multi-queue apparently works! ovs-vswitchd consumes more that 100%
  of CPU, meaning that it multi-queue is there...

   *** Where it fails?

   1- Reboot the VM and try to run ethtool again (or go straight to 2
  below):

   ethtool -L ens5 combined 4

   2- Try to fire up ens4:

   ip link set dev ens4 up

  
   # FAIL! Both commands hangs, consuming 100% of guest's CPU...

   So, it looks like a Linux fault, because it is "allowing" the DPDK
  VirtIO App (a user land App), to interfere with kernel devices in a
  strange way...

  Best,
  Thiago

  ---
  # lspci | grep Ethernet
  00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:04.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:05.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:06.0 Ethernet controller: Red Hat, Inc Virtio network device
  ---

  Where "ens3" is the first / default interface, attached to Libvirt's
  "default" network. The "ens4" is reserved for "ethtool / ip" tests
  (attached to another Libvirt's network without IPs or DHCP), "ens5"
  will be "dpdk0" and "ens6" "dpdk1"...

  ---
   *** How it works?

   1- For example, try to enable multi-queue on DPDK's devices, boot
  your Xenial guest, and run:

   ethtool -L ens5 combined 4
   ethtool -L ens6 combined 4

   2- Install openvswitch-switch-dpdk configure DPDK and OVS and fire it
  up.

   https://help.ubuntu.com/16.04/serverguide/DPDK.html

   service openvswitch-switch stop
   service dpdk stop

   OVS DPDK Options (/etc/default/openvswitch-switch):

  --
  DPDK_OPTS='--dpdk -c 0x1 -n 4 --socket-mem 1024 --pci-blacklist 
:00:03.0,:00:04.0'
  --

   service dpdk start
   service openvswitch-switch start

   - Enable multi-queue on OVS+DPDK inside of the VM:

   ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=4
   ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0xff00

   * Multi-queue apparently works! ovs-vswitchd consumes more that 100%
  of CPU, meaning that it multi-queue is there...

   *** Where it fails?

   1- Reboot the VM and try to run ethtool again (or go straight to 2
  below):

   ethtool -L ens5 combined 4

   2- Try to fire up ens4:

   ip link set dev ens4 up

  
   # FAIL! Both commands hangs, consuming 100% of guest's CPU...

   So, it looks like a Linux fault, because it is "allowing" the DPDK
  VirtIO App (a user land App), to interfere with kernel devices in a
  strange way...

  Best,
  Thiago

[Kernel-packages] [Bug 1570195] Re: Net tools cause kernel soft lockup after DPDK touched VirtIO-pci devices

2016-05-04 Thread Launchpad Bug Tracker

This bug was fixed in the package dpdk - 2.2.0-0ubuntu8

---
dpdk (2.2.0-0ubuntu8) xenial; urgency=medium

  * d/p/ubuntu-backport-[36-37] fix virtio issues (LP: #1570195):
- don't let DPDK initialize virtio devices still in use by the kernel
- this avoids conflicts between kernel and dpdk usage of those devices
- an admin now has to unbind/bind devices as on physical hardware
- this is in the dpdk 16.04 release and delta can then be dropped
- d/dpdk-doc.README.Debian update for changes in virtio-pci handling
- d/dpdk.interfaces update for changes in virtio-pci handling
  * d/p/ubuntu-backport-38... fix for memory leak (LP: #1570466):
- call vhost_destroy_device on removing vhost user ports to fix memory leak
- this likely is in the dpdk 16.07 release and delta can then be dropped
  * d/p/ubuntu-fix-vhost-user-socket-permission.patch fox (LP: #1546565):
- when vhost_user sockets are created they are owner:group of the process
- the DPDK api to create those has no way to specify owner:group
- to fix that without breaking the API and potential workaround code in
  consumers of the library like openvswitch 2.6 for example. This patch
  adds an EAL commandline option to specify user:group created vhost_user
  sockets should have.

  Guys,

   I'm facing an issue here with both "ethtool" and "ip", while trying
  to manage black-listed by DPDK PCI VirtIO devices.

   You'll need an Ubuntu Xenial KVM guest, with 4 VirtIO vNIC cards, to
  run those tests

   PCI device example from inside a Xenial guest:

  ---
  # lspci | grep Ethernet
  00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:04.0 Ethernet controller: Red Hat, Inc Virtio network device
  00:05.0 Ethernet controller: Red Hat, Inc Virtio network device

[Kernel-packages] [Bug 1573062] Re: memory_stress_ng failing for IBM Power S812LC(TN71-BP012) for 16.04

Can you test the 4.1 kernel next?  It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-wily/

We may also want to test the latest mainline kernel to see if this bug
is already fixed there.  If it is, we can perform a "Reverse" bisect to
find the fix.  The mainline kernel is available from:

2016-05-04 Thread thom

Maybebut it is not supposed to cause such weird side effects

I ended up doing a git bisect myself on this issue:

https://bugs.freedesktop.org/show_bug.cgi?id=87682
(because it's an upstream bug)

Anyone any tips how to continue ?

Bug description:
  Ubuntu-Mate 14.04.2

  This is what I get if I run a kernel newer than 3.13: 
https://www.youtube.com/watch?v=nx2-Fvihzxg
  sorry for the link, I just don't know how to describe these artefacts 
verbally.
  (a storm of small horizontal moving blips from right to left ??)

  Those artefacts appear as soon as new kernel is selected in GRUB, and
  remain during the whole session.

  The lastest kernel (from the main repository that is) working without
  artifacts is v3.13.0.59. All later kernels have artifacts. All later
  kernels also are either "-utopic" or "-vivid" instead of "-trusty",
  but I do not know if it is related.

  
  GPU: Mobility Radeon HD 3200 (RS780M)
  System: Ubuntu Mate 14.04.2  32-bit

  Kernels tested: 3.13.0.59 (and earlier) , 3.16.0.45 , 3.19.0.25 
  Only  3.13.0.59 (and earlier) are without problems.

@faulpeltz,

I am continuing to test the next test kernel up to commit:

Are you testing 3.13.0-34.60 or would you be wiling to do that?  Just to
confirm it does not contain the bug and the bisect was started at the
correct versions.

midnight on the host and finishes an hour and half later.   
  Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct 
kernel version we have.   We're currently running kernel version 
3.13.0-49-generic #83 on one system and 3.16.0-34-generic #37 on the other. -- 
We see the same errors on both.
  As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 
hyper-v system because of this.   We can stop the backup process and all is 
good, but we need nightly backups to image all of our VM's.   All the windows 
guests have no issues of course.   We also have some CentOS based guests 
running without issues from what we've seen.

[Kernel-packages] [Bug 1568865] Re: [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] ERROR CPU pipe B FIFO underrun

2016-05-04 Thread Simon Ransome

I see the same FIFO under-run issue in Kubuntu 16.04. The manifestation
appears to be either the laptop display remaining totally blank (but not
disabled - the pointer appears to travel through it) on boot-up, resume
from lid-open or resume from screensaver, or the display going blank
when the mouse pointer enters the laptop screen and resuming when the
pointer exits - but always in the presence of a second display connected
over HDMI. Temporary "fixes" have so far included closing the lid and
opening (often seems to resolve the blank state from screensaver) and
unplugging and re-plugging HDMI, which sometimes sorts the blanking on
mouse pointer problem.

sample errors:

[   90.483130] [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU

Bug description:
  Running Gnome-Shell on ubuntu 16.04 on my Dell XPS 15 9550 laptop
  using Intel graphics (Nvidia card turned off), I get this error in
  syslog when plugging in an external monitor (HDMI).

  Meanwhile both screens flash and show corruption. Most of the time
  this has caused a hang that needs a hard power off to get out of, but
  occasionally removing the external monitor is enough to get going
  again and so I've been able to find this message in the logs.

  Note that when using Nvidia (proprietary) drivers and Unity DE I do
  not have this problem; so it seems to be related to the intel drivers,
  or possibly Gnome Shell's use of them.

  Happy to help if I can (would like to be able to use external
  monitors!)

Bug description:
  The following patch has been submitted upstream in response to
  investigation of customer issues with network connections hanging
  under high load.

  On the consumer side, we have interrupt driven flow management of the
  producer. It is sufficient to base the signalling decision on the
  amount of space that is available to write after the read is complete.
  The current code samples the previous available space and uses this in
  making the signalling decision. This state can be stale and is
  unnecessary. Since the state can be stale, we end up not signalling
  the host (when we should) and this can result in a hang. Fix this
  problem by removing the unnecessary check.

  I would like to thank Arseney Romanenko 
  for pointing out this bug.

[Kernel-packages] [Bug 1559576] Re: Ubuntu GNOME boots to black screen when using proprietary Nvidia drivers on a laptop with Optimus

2016-05-04 Thread Tassos

I upgraded the following packages on 2016.5.3:

nvidia-common:amd64 (1:0.4.17, 1:0.4.17.1), ubuntu-drivers-common:amd64
(1:0.4.17, 1:0.4.17.1)

And the black screen showed up again. I had to switch back to lightdm to
login. Hope this information help...

  Regular Ubuntu works absolutely fine on the same machine with the same driver

  Bug is affecting more than just me. We were talking about workarounds

[Kernel-packages] [Bug 1567418] Re: intel_modeset_check_state+0x88e/0x8a0 [i915_bpo]

I had this issue too with a new Dell Precision 5510 and 16.04 (also
Skylake).

I found setting  i915_bpo.preliminary_hw_support=1 seems to help -- any
chance that works for you too?

[Kernel-packages] [Bug 1578022] Re: dmidecode fails to output smibios 3.0 info

2016-05-04 Thread Colin Ian King

Can you supply some more information:

1. Which kernels were being used?  (RH 7.2 and Ubuntu)

2.  Can you tar up the /sys/firmware directory on both systems so I can
see if there any obvious differences at the interface level.

You will need to do that as root to be able to read the data.

Thanks

[Kernel-packages] [Bug 1578022] Re: dmidecode fails to output smibios 3.0 info

2016-05-04 Thread Jeff Lane

We found this during certification testing of a couple models from one
OEM that apparently use SMIBIOS 3.0.

The failed test shows this in the output:

mmap: Can't map beyond end of file /sys/firmware/dmi/tables/DMI
Table is unreachable, sorry.
*** Incorrect or unknown server chassis type!

Failed 1 test (see above)

We also capture output of dmidecode in the test logs, on the 3.0 system
this is all we get in output:

  After OTA-9 I started having trouble with my bluetooth connection to the car

number), so I have reset both the car and the phone connections (eg. forgot the 
devices).
  Now I can't even pair the phone with the car's system. 
  The car finds the phone, and then asks me to enter the code "" to pair 
the device, but after a few moments, it just says the connection failed and 
asks me to try again. Which fails again.

  It was working fine just before the update.

  Any logs I should post to help debug?

  PS - The car is a 2015 Honda Civic Tourer, if that matters.

[Kernel-packages] [Bug 1578178] [NEW] Caller ID not displayed using in-car bluetooth system when recieving a call

Public bug reported:

When the phone is connected to the in-car hands free bluetooth system and I 
receive a call, I expect the caller ID to be displayed in the car's 
infotainment system. This was working until OTA9, which has made the system 
display "Unknown" when receiving a call.
I can use the phone's contacts from the car, so no everything is broken in that 
respect.

Would a verbose bluetooth log be helpful
(https://wiki.ubuntu.com/DebuggingBluetooth), or would something else be
required to help further investigate?

With a lot of effort and million monkeys on the keyboard I was finally able to 
get Xenial to access Windows 10 printer.
Yakkety Yak same problem all over again.  
I'll flail around a bit and open another bug if necessary.
Conclusion, Ubuntu developers don't have a Windows 10 on their network to check

[Kernel-packages] [Bug 1578176] Re: Cannot place or recieve calls when using in-car bluetooth system

I should also add that *before* OTA9 the entire system worked
flawlessly, so this is likely related to the update to Bluez5.

  After working around bug
  https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1539158 I was
  able to pair the phone (BQ Aquaris E4.5) with the car hands-free
  system.

  However, thing don't quite work as expected.
  I can use the car's system to place a call using the phone, but The audio is 
not getting properly routed. After placing the call, I can't hear any sounds 
(not even the "ringing" noise), I don't get any feedback after the other person 
has answered the phone, and the other person can't hear me either.

  Furthermore, Long after the other person has hung up the call, the
  phone still looks like the call is ongoing (I have to manually
  disconnect it).

  I can also use the system to answer an incoming call, but the
  sympthoms are the same. No audio on either end.

  Would a debug log be helpful in this situation 
(https://wiki.ubuntu.com/DebuggingBluetooth)?
  Or is something else required?

[Kernel-packages] [Bug 1568865] Re: [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] ERROR CPU pipe B FIFO underrun

FWIW I still have this issue without Unity and Compiz running, so I
don't think it has anything to do with those. I don't see any relevant
logging from X even after starting it with -logverbose 6.

Assuming this is what's responsible for the issue, to me this is quite a
major bug as it prevents use of external display together with the
laptop screen.
