--- Comment #7 from Anisse Astier anisse@astier.eu 2012-09-18 16:46:05 --- After about 180 reboots, I can confirm that this bug isn't present anymore on drm-next-3.7-wip. But I wasn't able to find commit 375849ce878f1a2dfac12ea2a62b361ab6b7f9a5 . Which commit do you think contains the fix ?
I still have a seemlingly unrelated "screen off/lockup on reboot" problem (that shouldn't be a regression). But this is a story for another bug report.
