I see, thanks.
Support for this GPU seems to have been added by
cc22a938fc1d drm/i915: add Ivy Bridge GT2 Server entries
which was merged in 3.4-rc2.

Can you get a trace of the crash using a serial console[1] or
netconsole[2]?
If so, please report this to bugs.freedesktop.org, following
instructions from "http://intellinuxgraphics.org/how_to_report_bug.html";,
and let us know the bug number so we can track it.
Hope that helps,
Jonathan
