Reverting that whole patch on v3.17-rc5 is not as easy because then compile
fails.

Test for reverting the patch in question.

It's unlikely that the patch you mentioned causes such problems, but the patch
directly before this one could.

The attached patch (on top of Alex drm-fixes-3.17 branch) reverts this patch
and adds a few extra debug log lines.

So please test and report back with a new dmesg log.

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

Fix typo 'addr' -> 'entry' in rs400_gart_set_page

Does this patch fix the problem?

Please test it without Christian's patch, that one can't work correctly because
it doesn't set the correct GART page flags in all cases.
