Description Richard Schwarting 2009-10-25 10:58:02 UTC 
Description of problem:
I'm running Fedora 12 Beta (via a USB stick) on an IBM Thinkpad X41t (has an Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)).  This behaviour did not occur in Fedora 12 Alpha.

Applications/System Tools/System Monitor, System/About this Computer, and resuming from Suspend all cause X to crash with a similar backtrace:

How reproducible:
Always

Steps to Reproduce:
1. Click on System Tools
2.
3.
  
Actual results:
X dies, I see a black terminal briefly, and then GDM comes back up.

Expected results:
System Tools should come up.

Additional info:
I'm running Fedora 12 Beta from a Live USB stick.

I'm not sure if it's relevant, but I also end up seeing this in dmesg

Comment 1 Richard Schwarting 2009-10-26 07:15:27 UTC 
I'll note that on another laptop, that opening System Tools (which I now realise is what About this Computer opens) does not crash X, but this other computer uses an AMD/ATI chipset.
Comment 2 Richard Schwarting 2009-10-26 07:53:48 UTC 
I'll note that it doesn't do it with Xephyr inside the same session.

Magic stacktrace

Here is a stacktrace that I obtained by doing this via SSH:
X :2
gdb --pid=<the PID of the above X session>
DISPLAY=:2 gnome-system-monitor

I couldn't do it locally because running gdb on X locally locks up my system (for some reason I don't understand).

If I could produce a more useful one with fewer values optimised out, I'll gladly do it.
Comment 4 Richard Schwarting 2009-10-26 08:45:50 UTC 
I take it that the two uxa_ functions are the ones earlier reported in intel_drv.so in the less-useful stacktrace?  I'll try with exa or xaa later, I guess.
Comment 5 Richard Schwarting 2009-10-26 12:04:38 UTC 
Using the "vesa" driver, I do not run into the same problem.  System Monitor appears as expected, no crash.

I tried to set 
Option "AccelMethod" "exa" 
and
Option "AccelMethod" "xaa"
and
Option "NoAccel" "True"
but from what I could tell from the Xorg.0.log, UXA was used anyway.

Xorg.0.log including crash with intel driver

This is the Xorg.0.log.old that's left behind after X crashes.  Intel and presumably UXA acceleration.
Comment 7 Richard Schwarting 2009-10-26 12:28:18 UTC 
I'll note that trying 
xorg-x11-drv-intel-2.9.0-3.fc12 
xorg-x11-drv-intel-2.8.0-16.20090909.fc12
from koji suffered the same issue.

(The beta comes with 
xorg-x11-drv-intel-2.9.0-2.fc12)
