on bug 85204
from Johannes Hirte
Same problem with a Mobility Radeon HD 5470 Cedar here. But I first noticed with 3.18 kernel. 3.18-rc1 seems to be fine. I've never seen a lockup with this version. Bisect points at least to 3.18.0-rc1-00005-g031d705. I've stopped bisecting here, cause this doesn't make sense. All commits here are from v4l tree and don't look like affecting graphics. Maybe 3.18-rc1 is bad too and I only didn't hit the bug with this version. the log shows me this with linux-3.18: Jan 5 18:16:13 acer kernel: radeon 0000:01:00.0: ring 0 stalled for more than 10020msec Jan 5 18:16:13 acer kernel: radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000450cf last fence id 0x00000000000450ea on ring 0) Jan 5 18:16:13 acer kernel: radeon 0000:01:00.0: failed to get a new IB (-35) Jan 5 18:16:13 acer kernel: [drm:radeon_cs_ib_fill] *ERROR* Failed to get ib !
