[Kernel-packages] [Bug 1938999] Re: External displays not working on Thinkpad T490 with ThinkPad Thunderbolt 3 Dock

2021-08-16 Thread Bin Li

@aaron,

Tried the 5.11.0-26.28-lp1938999-generic kernel, it works fine. You
could check more about it from this log. Thanks!

Title:
External displays not working on Thinkpad T490 with ThinkPad
Thunderbolt 3 Dock

Status in linux package in Ubuntu:
Confirmed

Bug description:
I have two external displays chained via Display port connected to the
ThinkPad Thunderbolt 3 Dock.

They are working with kernel 5.8.0-63 but not with the new 5.11.0-25
kernel.

I could reproduce this behavior several times for both kernels, as
follows: I booted up with disconnected dock, logged in, then I
connected it, disconnected it, and connected it again.

With the 5.11.0-25 kernel the external displays go black; the main
screen turns off and on several times. Sometimes the main screen
remains working, but UI is lagging.

I'm attaching the logs. Two separate boots for each variant are marked
'a'/'b'.

Bug description:
  [Impact]
  To support AMD Radeon Pro W6600/W6700 graphic card, we need some new firmware.

  [Fix]
  AMD suggests us to include below 2 commits, and to avoid conflicts I cherry 
pick sienna cichlid firmware from the beginning when it's been added. Impish 
already have both commits.

  amdgpu: add initial dimgrey cavefish firmware from 21.20

  [Test]
  Verified on AMD Radeon Pro W6600 graphic card.

  [Where problems could occur]
  This series of patches introduce dimgrey cavefish and sienna cichlid 
firmware. The 2 GPUs are still new and have little chance to affect old 
platforms, should be safe to include them.

[Kernel-packages] [Bug 1940154] Re: Xorg freeze (nouveau/ttm use-after-free with full-screen video)

2021-08-16 Thread Daniel van Vugt

Thanks for the bug report. That's a kernel crash in the nouveau driver.
But that driver is not well supported so we would usually recommend the
official Nvidia driver instead. Unfortunately:

1. Your GeForce 310M GPU requires the Nvidia 340 driver only. Newer
drivers don't support that GPU; and

2. The Nvidia 340 driver is no longer supported by Nvidia and no longer
shipped in Ubuntu 21.04.

I suggest using only Ubuntu 20.04 on this machine, which has a working
version of the Nvidia 340 driver that you can install via the
'Additional Drivers' app.

Status in linux package in Ubuntu:

Bug description:
  Since upgrading to Ubuntu 21.04 yesterday, I've noticed several hangs
  during full-screen video playback (watching Youtube videos in
  Chromium). Often, it happens just after or during the switch to full-
  screen.

  The system stays running and I can connect via ssh, but restarting
  gdm3 has no effect and most of the time I've had to reboot. The latest
  hang recovered automatically when I left the machine alone for about 2
  minutes, and produced the following messages in dmesg (I'll attach a
  more complete log):
