--- Comment #2 from Alexandre Demers alexandre.f.demers@gmail.com 2011-12-11 09:00:57 UTC --- More info about this bug: I have both kernel 3.1.0 and 3.2.0-rc4 installed right now (compiled from kernel.org). I had 3.2.0-rc3 installed, before moving to rc4 to test if the bug had been solved.
Have I updated other components? Of course, I'm testing with latest versions of both mesa and xf86-video-ati (I'll have to test today's versions though). But then, it shouldn't be a problem since I'm testing the same components with both kernels.
I'll bisect kernel's commits in the next couple of days to find which one is breaking things.
