dmesg output showing fcrash in i915 driver

Description of problem:

  Upgrading an MSI Wind U100 clone from kernel 4.2.8-300 to 4.3.3-300
  breaks video output.  I attached the dmesg output which contains a
  kernel stackdump.

  After searching for this effect on the net I found this related
  issue on freedesktop.org:

    https://bugs.freedesktop.org/show_bug.cgi?id=92655

  and a matching patch

    https://bugs.freedesktop.org/attachment.cgi?id=119541

  Is it possible that this fix is missing in 4.3.3?

Version-Release number of selected component (if applicable):

  kernel-4.3.3-300.fc23.i686

How reproducible:

  Install aforementioned kernel on a MSI Wind or clone thereof with F23
  Reboot

Actual results:

  Garbeled video output

Expected results:

  Working video

Yes.  There are many patches marked for stable that are not in a stable release because the upstream maintainer is very behind.  This happens to be one of them.  It was only added into 4.4-rc6.

Please test this scratch build when it completes and let us know if it helps:

Hi Josh,

the test kernel you provided works as desired in terms of the
video problem on i915.


Thanks a lot,
Corinna
Comment 3 Alex Villacís Lasso 2016-01-14 15:44:27 UTC 
Also occurs on an Acer Aspire One ZG5. In my case the screen corruption affects the plymouth splash screen and leaves a black rectangle with random garbage filling 3/4 of the screen horizontally.

Thanks for testing!

Comment 8 mm19827 2016-01-19 20:39:02 UTC 
Had the same problem on a Dell Latitude D620 with i945GM
With kernel-4.3.3-301.fc23 no garbage on screen, but the GNOME desktop is _very_ slow (not really usable), top shows gnome-shell consuming 100% CPU.

KDE and Xfce run fine.
Same with With kernel-4.3.3-302.fc23
possibly the same as reported in Bug 1299933

dmesg log on Acer Aspire One ZG5 with kernel-PAE-4.3.3-301.fc23.i686

The bug is only partially solved for me. I don't get the screen corruption anymore but backtraces still appear in the kernel log.

dmesg kernel.4.3.3-303.fc23.i686+PAE with multiple drm backtraces

Still having bad behaviour from the GNOME desktop with kernel-PAE-4.3.3-303.fc23.i686
Just displaying the Activities menu takes 10 secs.

A number of drm backtraces are seen in the kernel log, which has no backtraces with kernel 4.2.8.
FWIW, note that my CPU does not support PAT - switch from MTRR to PAT has been a major change for kernel 4.3

Despite the backtraces, xfce and KDE behave properly.

dmesg attached for both 4.3.3.303 and 4.2.8
Comment 15 Fedora Update System 2016-01-26 18:22:43 UTC

Comment 16 Richard Henwood 2016-01-31 22:36:54 UTC 
One data point:

I am using a Compaq Presario v6000, i686. Had very slow video with 4.3.3-30{1,2,3}.

I've booted into 4.4.0-1.vanilla.knurd.1.fc23.i686 from
https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories
it's not great, but machine feels much more responsive and I consider it usable.
