bisected and first bad commit is: 8696e33f06b0c52195152cc6a0e3d52233f486c1 commit 8696e33f06b0c52195152cc6a0e3d52233f486c1 Author: Alex Deucher alexander.deucher@amd.com Date: Thu Dec 13 18:57:07 2012 -0500
drm/radeon: bump version for CS ioctl support for async DMA Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
That just enables the use of DMA by the 3D driver, so the issue is in mesa. This looks like a duplicate of bug 60236.
You are right, that's what I thought about the bad identified commit.
I don't have the same symptoms as in bug 60236, but I'll have a look anyway. Otherwise, I'll use kernel 3.8-rc7 and I'll bisect mesa to track the bug down.
