Repeated Xorg crashes with intel driver

[Tom Evans-3]

Hi all.

I'm getting repeated crashes in Xorg. It works fine (well, no crashes.)
for a long period before dieing (15 days, then 1 day). The annoying
thing is that after the crashes, it appears the hardware is left in an
unusable state, and I have to reboot to bring X back.

I've uploaded pertinent config files and log files to a server, as I've
never had much luck getting them through the mailing list :)

http://87.194.39.182/fbsd/xorg_crashes/

I'm not running quite the latest versions of the driver, as it gave me
significant performance degradation as an (enforced) non DRI user.

> $ egrep drm\|xorg-server\|intel /root/xorg_crashes/pkg_info.txt
libdrm-2.3.0        Userspace interface to kernel Direct Rendering
Module servi
xf86-video-intel-2.2.1 Driver for Intel integrated graphics chipsets
xorg-server-1.4.2,1 X.Org X server and related programs

So, the first thing I will do is update to the latest versions, and see
if crashes are still reproduced. I may also try Robert Noland's proposed
DRM changes for RELENG_7.

Any other ideas?

Cheers

Tom

Following up my own email, these infuriating, unpredictable crashes
still happen. I can't reproduce them on demand, either. Sometimes it is
hours between crashes, sometimes days.

I have updated the driver and libdrm to the latest versions:
libdrm-2.3.1        Userspace interface to kernel Direct Rendering
Module servi
xf86-video-intel-2.4.2 Driver for Intel integrated graphics chipsets

This is with RELENG_7 from 15/9/08.

I'm rebuilding now with the latest RELENG_7, with Robert Noland's DRM
patch from
http://people.freebsd.org/~rnoland/drm-update-7-100308.patch.bz2 .

If this doesn't work, I will be reverting to 7.0 release, which worked
perfectly. I cannot have this machine crashing out of X whenever it
feels a little shaky.

Cheers

Tom
