I've been following this ticket and attempting to poke around a bit. I
just tested my hardware with various points in the 3.6, 3.7, and 3.7-rc
kernels, and all of those still gave me a non-responsive screen with
messages like the following after resume. e.g., on Linux 3.6:
[ 161.192867] [drm] nouveau 0000:01:00.0: Failed to idle channel 2.
[ 164.355897] [drm] nouveau 0000:01:00.0: Failed to idle channel 4.
or on Linux 3.7.9:
[ 336.337207] nouveau E[ 3134] failed to idle channel 0xcccc0000
None of these builds give me a PAGE_NOT_PRESENT error, though. This
makes it hard to bisect, as I can't find any working point to test...
