You are seeing the same symptom, but that does not necessarily mean that
it is the same problem.  See
http://nouveau.freedesktop.org/wiki/TroubleShooting#Igetthe.22EQoverflowing.22error
for more explanations.

 I use a kernel 2.6.39-2 .
 I attach a xorg-log which contain the crash.

Thanks.  This looks somewhat odd to me:

 [   113.586] Segmentation fault at address 0x3393938

 Fatal server error:

 Please consult the The X.Org Foundation support

 [   142.490] [mi] EQ overflowing. The server is probably stuck in an infinite 
 loop.

How come that the X server tries to continue after the segfault?

 Is there any news about upstream fixes for this bug?
 Do you need any logs?

You could try to debug the problem yourself, please see
http://pkg-xorg.alioth.debian.org/howto/use-gdb.html for instructions.
Trying different kernels might also be useful.

In any case, please open a new bug if you find out anything
interesting.  The current one is already unusable.

Cheers,
   Sven

Sven, thanks a lot for your help.

 Please send any further followups to bug #610987 instead.

  01:00.0 VGA compatible controller [0300]: nVidia Corporation GT218 [NVS 
  3100M] [10de:0a6c] (rev a2)

 You may want to try kernel 2.6.39-rc5 from experimental.  If you run
 into http://bugs.debian.org/625279, wait for 2.6.39-rc6 to become
 available. 

I am running 2.6.39-rc6 since about 5 days and the lockups have disappeared so 
far.

Stefan.

 My kernel version and hardware differ from those of the original reporter, 
 but symptoms are the same.

This does not necessarily mean that it's the same problem.

This is one of the cards that suffer from
https://bugs.freedesktop.org/26980 aka http://bugs.debian.org/610987.

You may want to try kernel 2.6.39-rc5 from experimental.  If you run
into http://bugs.debian.org/625279, wait for 2.6.39-rc6 to become
available.  In the meantime, disabling acceleration should work around
the hangs, e.g. boot with nouveau.noaccel=1 kernel parameter.

Regards,
Sven

Bug#578056: EQ overflowing. The server is probably stuck in an infinite loop.

2011-05-06 Thread Stefan Schwarzer
Package: xserver-xorg-video-nouveau
Version: 1:0.0.16+git20110411+8378443-1
Followup-For: Bug #578056


I am posting this hoping to supply additional info. 
My kernel version and hardware differ from those of the original reporter, 
but symptoms are the same. About 1 - 10 min into a session, the interface
freezes (cursor still ok), mostly associated with some activity on the 
system (browsing, DVD burning, moving windows around, etc.)
The lockup is random and concerns X11 only, Rest of the system is ok.
Login from the network shows Xorg busy.
After killing the server (-9), there is a message left on the console: GPU 
lockup
probably just before the kernel does what is necessary to (re)start nouveaufb 
(??? I am guessing). Also the 'positioning' cursor cross is stuck in the middle 
of the console.

My system is a Dell laptop E6410, BIOS A06. I do not think that there is a HW 
issue
since with the vesa driver the system is mostly ok (backlight issue on resume).
