since I've got no replies, I'm going to close this bug report for
now. Feel free to file a new one if you're still having issues:

thanks for the hint. I can't reproduce it though, all I'm getting is:
| i915_program_error: Exceeded max nr indirect texture lookups (5 out of 4)

Are you still getting this with the X stack from squeeze/sid (or from
experimental if you have a chance to test that)?

In that case, http://pkg-xorg.alioth.debian.org/howtos/use-gdb.html
might be useful to get some info from the crash.

I've investigated a little bit more and realized that the responsible of
crashings is actually a compiz extension : when alpha_blur is enabled to
any windows, it makes X crahing.
I think that severity can be decreased to low, as problem can be worked
around just disabling an extension.

Please upgrade to 2.6.32-4 currently in sid.

If the problem still happens, we need the backtrace of the crash (see
the end of Xorg.0.log, or (better) get it with gdb).

Please try with -4 instead of -3, plenty of bugfixes.

Mraw,

Description :
System freezes, crashes and comes back to gdm screen as soon as I'm
handeling some fullscreen windows with compiz enabled.
It's a fresh install of debian SID (less than 2 weeks), problem appears
for the first time this morning (19 april 2010), after the latest
upgrade of Xserver-xorg paquets.

Workaround :
Disabling compiz

Thank you
