oops output from dmesg
Ever since switching to drm-intel-nightly to test some patches a while back, my
IVB MBA has been oopsing on a regular basis when running piglit quick.tests in
a gnome-shell session.
Oops will be attached, but an excerpt:

Apparently at some point my kernel config rotted and lost debugging symbols;
I've found the knob to reenable and built a new one so next time I'll be able
to get line info.
Kernel commit:

Merge remote-tracking branch 'drm-upstream/drm-next' into drm-intel-nightly
Note that I was also experiencing this problem without kwg's stuff -- it
started when I was trying to get a patch tested for Ben.</pre>
