Does this happen all the time ? yes - could this be sideport related? (In reply to comment #3) > yes - could this be sideport related? > Not likely. I tried to bisect this and found that 2.6.32 also has this issue (I got this system a few weeks ago only). 2.6.31 shows "ring test failed" and I guess support for rs785 was not added earlier. So this chip seems to never have worked with KMS. I also tested the kernel from fredora 13a to see if I have a problem with my config, but it also shows fence errors. Other failed tests: Sideport -> UMA, limit memory from 4G to 2G. As this bug happens on a released kernel and also crashes X sometimes, I changed the severity to critical. tried with nosmp, mem=2G (out of 4) and NO_HZ, NO_PREEMPT - no change. below is the log with glisse drm-radeon-next tree (grr - again slow chip clock default): [ 7.940041] [drm] Initialized drm 1.1.0 20060810 [ 8.479532] [drm] radeon defaulting to kernel modesetting.

Unfortunately, I cannot test the GPU reset patches alone, as they do not apply to 2.6.33. Jérôme, could you please supply something relative to 2.6.33?
Thanks!
Created attachment 34022 [details] [review] backported patch This bug report looks like a soliloquy. Anyway, I backported "drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4" myself to 2.6.33 and it fixes this problem. Can this be forwarded to upstream->stable? Is it possible that bug 32662 is related to this one? |
