Comment # 11 on bug 1119621 from David Rosky

Since this seems to be kernel-related, and the only logged error you see is
drm-related, it might be worth trying the development kernel from drm-tip.  In
case you weren't following it (I opened a new bug), this ended up solving the
problem I was having that I reported here a few comments back.  The symptoms
are different, but it might be worth a try.  Besides addressing newer
processors, it may be that some regressions were introduced in the DRM code
that are just now getting cleared up.

After a bit of searching, the DRM development kernel turned out to be pretty
easy to compile according to instructions in a post I found that is linked to
in the bug I opened (which I've since closed):
