[Intel-gfx] KMS issues on lid close v2.6.32-rc6

[Gary Trakhman]

Hey all,
I've got a GM45 thinkpad sl300 running 2.6.32-rc6 in an attempt to get
latest and greatest drm.  I've noticed similar behavior in past
releases as well.  Basically, if I close the lid on my laptop, it
either works properly, turns the screen black and I have to ctl-alt-f1
ctl-alt-f7 to get back to X, or it will hang the gpu and kill gdm.
Gdm will then restart but on virtual terminal f8.  How do I go about
testing this meaningfully to file a good bug report, or is there a fix
already?

Here's some seemingly relevant lines from dmesg after multiple lid closes.
