The assumption is "this problem" is only one problem.  At last count, there's
been like 947 similar bugs with the i915 (possibly a slight exaggeration).
About all you can do here is turn on i915 debugging and dump the entrails
that result on the i915 maintainers and hope they can figure out what went
wrong *this* time....
