After the crash, the following error occured:

[2429052.434009] [drm:i915_gem_do_execbuffer] *ERROR* Failed to pin buffer 2 of 3, total 67125248 bytes: -28

Only with hard reset you can restore the system.

What crash? There's nothing here to imply a crash, though you might find the system is spinning and appears to have frozen. In which case this a probable dup of 20152 or 24369 [and https://bugzilla.kernel.org/show_bug.cgi?id=15911].

It seems that the specific behaviour from X came by the "page fault of doom"
from firefox.

Marking as a duplicate as a reminder to get on and try and get the patches ready for 2.6.36...
