Chris, please see comment #19 in this bugzilla entry, or, for a complete description, see bug #37450. In essence, it seems that stale DPMS properties (kernel bug 24982), which normally just result in a blank screen, can in some situations result in a crash/hang. When I originally reported it I could only trigger it after suspend/resume; nowadays I can reproduce it just by repeatedly enabling and disabling an output a few times. The only workaround that works for me is modifying the xf86-video-intel driver to force page flipping off.
