[Kernel-packages] [Bug 1208993] Re: Ubuntu slows down and hangs while copying file from/to USB

[Merlijn Sebrechts]

I feel like this is a lot better on Ubuntu 20.04. Anyone else have the
same experience?

  Ubuntu slows down and hangs while copying file from/to USB

Bug description:
  Hi

  While copying many and large files to and from a USB drive, the system
  becomes incredibly slow and sometimes hangs. I watched the system
  monitor while it was running slowly but cpu was not above 50% at any
  time, the same for memory.

  I'm using the "WD my passport" HD with a USB3 port of my "ASUS K55VD"
  laptop.

[Kernel-packages] [Bug 1208993] Re: Ubuntu slows down and hangs while copying file from/to USB

[Merlijn Sebrechts]

Thanks @peterrus!

I can confirm that using swapoff completely removes the hanging and
stuttering during heavy disk IO.

I don't see this only during file copy. Extracting archives, for
example, or saving virtual machine state to disk cause the same kind of
stuttering and hanging. It was impossible for me to import an .ova image
into VirtualBox when swap was on because my system became unresponsive.
After turning swap off, I can use virtualbox again!!

[Kernel-packages] [Bug 1759628] Re: bluez regression: Bluetooth audio fails to reconnect after resume

[Merlijn Sebrechts]

I've been using the bluez ppa for a while now and I haven't had any
issues with it. Before, I'd regularly have connection issues to my bose
qc 35. Now, I can always connect immediately, haven't had an issue
since.

I also noticed that my headset now connects a lot quicker than with the
stock 18.04 bluez.

So I'm really hoping that this can get included in mainline 18.04 as
soon as possible, this will make many users happy :)

Bug description:
  STEPS TO REPRODUCE:
  1. Connect to Bluetooth audio device
  2. Suspend & Resume
  3. Reconnect to Bluetooth device.

  This regression in bluez 5.48 has already been identified and fixed
  upstream. Report is here  and patch is here
  
.

  Syslog reports messages as follows when this issue is happening (I have 
replaced my device's MAC address with [MAC]):

  [regression] Kernel crash in bluetooth with Bose QC35

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Bose QC35 with latest firmware
  Ubuntu 17.10

  This is a regression from 17.04 Ubuntu Gnome. In 17.04, you had to
  temporarily disable `le` mode to pair but after pairing, everything
  worked flawlessly. In 17.10, pairing works out of the box, but the
  following issue appears:

  After a few hours of being connected, the connection between bose qc35
  and Ubuntu seemingly breaks: the headphones don't play any sound
  anymore. re-pairing fails and restarting the headphones doesn't fix
  the issue. It seems bluetoothd crashed conmpletely since
  `bluetoothctl` doesn't work anymore.. Restarting Ubuntu fixes the
  issue.


  
  syslog contains a bunch of kernel stacktraces including a nullpointer 
dereference..

  [regression] Kernel crash in bluetooth with Bose QC35

Bug description:
  Bose QC35 with latest firmware
  Ubuntu 17.10

  This is a regression from 17.04 Ubuntu Gnome. In 17.04, you had to
  temporarily disable `le` mode to pair but after pairing, everything
  worked flawlessly. In 17.10, pairing works out of the box, but the
  following issue appears:

  After a few hours of being connected, the connection between bose qc35
  and Ubuntu seemingly breaks: the headphones don't play any sound
  anymore. re-pairing fails and restarting the headphones doesn't fix
  the issue. It seems bluetoothd crashed conmpletely since
  `bluetoothctl` doesn't work anymore.. Restarting Ubuntu fixes the
  issue.

  Bose QC35 with latest firmware
  Ubuntu 17.10
  
  This is a regression from 17.04 Ubuntu Gnome. In 17.04, you had to
  temporarily disable `le` mode to pair but after pairing, everything
  worked flawlessly. In 17.10, pairing works out of the box, but the
  following issue appears:
  
  After a few hours of being connected, the connection between bose qc35
  and Ubuntu seemingly breaks: the headphones don't play any sound
  anymore. re-pairing fails and restarting the headphones doesn't fix the
  issue. It seems bluetoothd crashed conmpletely since `bluetoothctl`
  doesn't work anymore.. Restarting Ubuntu fixes the issue.
  
  
  
  syslog contains a bunch of kernel stacktraces including a nullpointer 
dereference..

This is the dmesg output before a crash. I'll add another dmesg output
when I get the next crash.

@joseph

I have not found a reliable way to replicate this bug so I cannot test
if it is still present in the latest upstream kernel.

I have attached the full syslog of multiple days + multiple crashes in
the second message in this thread. Does it give any hints as to how to
replicate this issue?

I can confirm that this issue is fixed in 17.10 daily image. Bose
QuietComfort 35 headphones now pair without issues.

It has been a while since I experienced this bug. It is possible that it
has been fixed during one of the OTA's.

[Kernel-packages] [Bug 1399611] Re: 8086:0046 [Acer Aspire 5742] Screen brightness not working

[Merlijn Sebrechts]

Hi Christopher. Apparently the problem is now fixed in the mainline
kernel. Even if I test it now with the 3.18 rc7 kernel, it is fixed. The
problem is still there if I use the 3.14 kernel, however.

I do not know how this happened. I suspect that after upgrading the
bios, I did not check with the 3.18 kernel, and the combination of new
bios + new kernel fixed it...

1) Do I email the acpi mailinglist to let them know the problem is fixed?
2) Will this fix ever be backported to the trusty kernel?

[Kernel-packages] [Bug 1399611] Re: Screen brightness not working acer aspire 5742

[Merlijn Sebrechts]

Thanks. I updated my bios using freedos (which was surprisingly easy to
do!).

sudo dmidecode -s bios-version  sudo dmidecode -s bios-release-date
V1.30
08/13/2012

This does not fix the problem. If I restart my laptop without the
workaround, the effect is still the same. When I change brightness, I
see the slider changing, but the brightness stays the same.

Title:
  Screen brightness not working acer aspire 5742

Status in linux package in Ubuntu:
  New

Bug description:
  My laptop does not respond to the screen brightness control after default 
Ubuntu install. The following workaround worked: http://askubuntu.com/a/450594
  It adds a config file to /usr/share/X11/xorg.conf.d/

  adding acpi_backlight=vendor to boot params did nothing
  adding acpi_osi=Linux to boot params only fixed the keyboard shortcuts, but 
the screen indicator and the brightness settings dialog stopped working.

  Please let me know if this is not the right package, or if you need
  more info.

[Kernel-packages] [Bug 1399611] Re: Screen brightness not working acer aspire 5742

[Merlijn Sebrechts]

removing the workaround (intel.conf file in
/usr/share/X11/xorg.conf.d/) and booting with the latest vivid kernel
(3.18.0-031800rc7-generic #201411302035) did not fix the problem.

Can someone explain me why the workaround works? Is the brightness
normally handled by the kernel and does my workaround tell the intel
driver to handle it?


Kind regards.

This is the first version of Ubuntu I installed. I do not know if this
