[Intel-gfx] [2.6.39 regression] hard lock when GNOME starts

[Andrew Lutomirski]

Hi-

Something in the range ^8aa7500 40c7f2112ce18fa5eb ^b04d0a90908c
causes by Q67 Sandy Bridge box to lock hard about one second after I
start GNOME.  It locks so hard that the reset button doesn't work and
netconsole doesn't say anything.

I'm about to have trouble finishing the bisection because I've had
trouble running revisions that are older than 2.6.38 and the next bit
of bisection has merge conflicts if I merge in 2.6.38.  I can power
through it, but maybe one of you will recognize the bug from the fact
that there aren't that many revisions in there and there can't be many
ways to make the reset button stop working.
