dmesg for linux-3.17_rc5 with
0001-Revert-drm-radeon-Remove-radeon_gart_restore.patch

I used a fresh version of 3.17-rc5 and applied your patch.
As you can see, your patch did not fix the bug.
I can't see new debug messages you mentioned.
Do I have to tell dmesg to be more verbose? How?

I'd like to test a revert of the commit that my bisect said it is bad.
But as I wrote, my first try ended in compilation fail. (undefined things).
What part of
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/radeon?id=77497f2735ad6e29c55475e15e9790dbfa2c2ef8
should I try to revert?

Tia
