[This bug has initially being reported against Debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=587149 ; this is mostly
copy/paste of what has been told there]

Hi,

I face X crashes (bug #1) and kernel oops (bug #2) when displaying
large images.

This might be two separate bugs, but since they share a common cause
I join them in a single report.  I am not sure either whether this is
the correct package to report the bug against, please feel free to
reassign it if I am wrong.

Bug#1:

This first time it happened, I was trying to display a 2200x1200 px png
image using qiv, a few days ago.  X crashed and I got back to gdm login.

Today, I tried to display a 3000x3000 px jpg image[1] in Iceweasel.  It
first crashed as above.  I got a backtrace in Xorg.log featuring calls
to the nouveau driver, but cannot be more precise since I sadly lost the
trace in subsequent crashes (see below) and have not been able to
reproduce it since then.  dmesg did not contain anything relevant about
this crash (see /var/log/syslog below @ 12:41:31 - gdm error message).

Bug #2:

I tried to load again the above-mentioned image and got a kernel oops;
a few seconds later, a second oops occurred and froze the machine.

After a reboot, I have been able to reproduce the bug:
- load the above image in Iceweasel,
- while it is loading (it takes some time), move the Iceweasel window
  and resize it.  [I am using Xmonad, so this basically boils down to
  open new terminal windows and change the layout.]
- some parts of the image become dark, you see a kernel oops in your
  terminal window, the image continues to load slowly, the second oops
  happens and then the screen becomes black. It always takes two oops to
  freeze.

Since I have a way to reproduce the bug, I can try to get more
information if you tell me precisely what you expect (I have no
experience of any kind with kernel/X debugging).

See the attached files syslog-2.6.32 (look for "Oops") and Xorg.log (nothing
relevant I fear).

Yes.  See the attached file syslog-2.6.34.


Note that this bug is very similar to a bug reported on the dri-devel ML:
http://www.mail-archive.com/dri-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org/msg46220.html
But this bug has been corrected:
http://www.mail-archive.com/dri-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org/msg47752.html
And the fix is included in linux-2.6_2.6.34-1~experimental where I can still
reproduce the problem, so this is likely a different issue (although similar).

You might also be interested by a similar bug reported by a Fedora user:
http://bugzilla.redhat.com/show_bug.cgi?id=595203

Gabriel Kerneis
