Hussein, I've looked a bit closer at the batchbuffer dump and it doesn't
look like any of the typical problems that we have in 945GM. It also
probably won't be fixed by the kernel patch I mentioned, since the bugs
it's supposed to fix have PGTBL_ER: 0x00000010 and you have a 0x0 (i.e.
not a page table error).

Before we send this upstream, I would like you to check if the bug still
is there is you run with the xorg-edgers PPA [1]. This will bring in the
newest version of xserver-xorg-video-intel, mesa, and libdrm so that we
know this bug has not been fixed there.

If the bug is still present with xorg-edgers (it probably is) we should
send this upstream with a set of consistent logs. That is, Xorg.0.log,
dmesg output, /var/log/dmesg (which is dmesg at boot, since this will be
missing from dmesg output due to the verbosity of drm.debug=0x02), and
/sys/kernel/debug/dri/0/i915_error_state from the _same_ run with kernel
2.6.34 with drm.debug=0x02 option. This should be with the xorg-edgers
packages installed as well. Please upload the files here for now.

In addition, since you seem to be able to reproduce this quite easily,
it could be useful with a couple of i915_error_state from different
crashes, so we can see if the batchbuffer where something goes wrong is
the same every time, and if not, what they have in common. Actually, you
may run intel_error_decode to get the decoded version of
i915_error_state and upload the decoded information directly.
