[Bug 986524] [NEW] radeon 0000:02:00.0: GPU lockup CP stall for more than 10000msec
You have been subscribed to a public bug: Often, the Xorg session freeze, go to black screen, and is display again. Most of the time Xorg stop to respond. I'm not sure what exactly is the cause of the problem, probably some instructions send to the GPU by compiz, which make the kernel GPU code to be locked. So my supposition is that the kernel code can have a deadlock situation. The only trace of error I have is in the kernel log (the kernel itself do not crashed): [ 808.804250] radeon :02:00.0: GPU lockup CP stall for more than 1msec [ 808.804255] GPU lockup (waiting for 0xA23F last fence id 0xA23E) [ 808.805394] radeon :02:00.0: GPU softreset [ 808.805398] radeon :02:00.0: GRBM_STATUS=0xB2703828 [ 808.805401] radeon :02:00.0: GRBM_STATUS_SE0=0x1C07 [ 808.805404] radeon :02:00.0: GRBM_STATUS_SE1=0x0807 [ 808.805407] radeon :02:00.0: SRBM_STATUS=0x20C0 [ 808.805422] radeon :02:00.0: GRBM_SOFT_RESET=0x7F6B [ 808.805526] radeon :02:00.0: GRBM_STATUS=0x3828 [ 808.805529] radeon :02:00.0: GRBM_STATUS_SE0=0x0007 [ 808.805532] radeon :02:00.0: GRBM_STATUS_SE1=0x0007 [ 808.805535] radeon :02:00.0: SRBM_STATUS=0x20C0 [ 808.806535] radeon :02:00.0: GPU reset succeed [ 808.832454] [drm] PCIE GART of 512M enabled (table at 0x0004).

My ATI card is an Sapphire Radeon HD 6850 1Go, and I use the free software driver. Using the previous version of Ubuntu I didn't have this error. I have almost no hope to have this bug fixed (too few infos, no one having it), but is there some method I can use to get more informations on this problem ? I will try a kernel debugging, but for a random bug, it will be more harder. Some day it crash, some it don't crash!
