using the 20100210.f0d760bf version of xorg. i get random crashes. 

also tracked on https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/525032 

see there for some attached files including lspci dmesg etc. 

uploading the XorgLogOld file here however. not sure how to diagnose this, will be happy to test in whatever way you guys suggest.

    drm/i915: Handle ERESTARTSYS during page fault
    
    During a page fault and rebinding the buffer there exists a window for a
    signal to arrive during the i915_wait_request() and trigger a
    ERESTARTSYS. This used to be handled by returning SIGBUS and thereby
    killing the application. Try 'cairo-perf-trace & cairo-test-suite' and
    watch X go boom!
    
    The solution as suggested by H. Peter Anvin is to simply return NOPAGE and
    leave the higher layers to spot we did not fill the page and resubmit
    the page fault.
