Hi,
I've also seen lockups in the intel DRI driver since about 1-2 weeks.
The responsible upgrade might have been some time before that since I
(didn't use to) reboot daily but use suspend.
I first thought it were 2.6.29 to blame, but I've now had comparable
lockups with 2.6.26, so that is ruled out.
Today, the lockup occured when switching to a tab in epiphany that had
an embedded gnome-mplayer (i.e. xvideo). I believe I can relate other
crashes to xv as well. Today it was just a plain lockup, with an
completely unusable X server, not doing any screen refresh (I believe
sometimes the mouse still worked, not sure about today).
I then used SysRq+K to kill the processed on the current terminal, which
caused GDM to restart the X server to recover. In other situations I've
had to reboot, and I can also remember the keyboard LEDs flashing (which
indicates a kernel panic).
Anyway, my Xorg.0.old log file shows:
exaCopyDirty: Pending damage region empty!

Fatal server error:
Caught signal 11. Server aborting
[... Unloading modules ...]
(II) AIGLX: Suspending AIGLX clients for VT switch
The last line sounds like a bad idea, since one of the unloading lines
before read (II) Video Bus: Close
I will install libdrm-intel1-dbg now, so maybe I'll be able to provide a
more detailed backtrace sometime. Of course I can't tell whether the
segfault in above logfile was before I had pressed SysRq+K or triggered
by that. However I had the impression that Xv triggered the crash, and
indeed the backtrace contains ProcXvDispatch and XvdiPutImage
Note that I have some packages from experimental installed, so my system
is not a plain "sid".
best regards,
Erich Schubert
