After updating to kernel 3.3-rc1 I have experienced a lockup of my GPU. I left my KDE desktop running until the screensaver turned off the monitors. But on key presses it would not turn back on. Ctrl+Alt+F1 to switch to another virtual console also did not work. Alt+SysRq magic still worked, so I was able to force the syslog to disk and restart the system. >From the log: Jan 21 19:30:01 thoregon cron[3960]: (root) CMD (test -x /usr/sbin/run-crons && /usr/sbin/run-crons) Jan 21 19:39:41 thoregon kernel: [ 6364.620131] radeon 0000:07:00.0: GPU lockup CP stall for more than 10000msec Jan 21 19:39:41 thoregon kernel: [ 6364.620139] GPU lockup (waiting for 0x0003F1F2 last fence id 0x0003F1F1) Jan 21 19:39:41 thoregon kernel: [ 6364.636341] radeon 0000:07:00.0: GPU softreset Jan 21 19:39:41 thoregon kernel: [ 6364.636348] radeon 0000:07:00.0: R_008010_GRBM_STATUS=0xA0003028 Jan 21 19:39:41 thoregon kernel: [ 6364.636354] radeon 0000:07:00.0: R_008014_GRBM_STATUS2=0x00000002 Jan 21 19:39:41 thoregon kernel: [ 6364.620131] radeon 0000:07:00.0: GPU lockup CP stall for more than 10000msec Jan 21 19:39:41 thoregon kernel: [ 6364.620139] GPU lockup (waiting for 0x0003F1F2 last fence id 0x0003F1F1) Jan 21 19:39:41 thoregon kernel: [ 6364.636341] radeon 0000:07:00.0: GPU softreset Jan 21 19:39:41 thoregon kernel: [ 6364.636348] radeon 0000:07:00.0: R_008010_GRBM_STATUS=0xA0003028 Jan 21 19:39:41 thoregon kernel: [ 6364.636354] radeon 0000:07:00.0: R_008014_GRBM_STATUS2=0x00000002 Jan 21 19:39:41 thoregon kernel: [ 6364.636359] radeon 0000:07:00.0: R_000E50_SRBM_STATUS=0x200000C0 Jan 21 19:39:41 thoregon kernel: [ 6364.636370] radeon 0000:07:00.0: R_008020_GRBM_SOFT_RESET=0x00007FEE Jan 21 19:39:41 thoregon kernel: [ 6364.651219] radeon 0000:07:00.0: R_008020_GRBM_SOFT_RESET=0x00000001 Jan 21 19:39:41 thoregon kernel: [ 6364.667212] radeon 0000:07:00.0: R_008010_GRBM_STATUS=0x00003028 Jan 21 19:39:41 thoregon kernel: [ 6364.667217] radeon 0000:07:00.0: R_008014_GRBM_STATUS2=0x00000002 Jan 21 19:39:41 thoregon kernel: [ 6364.667223] radeon 0000:07:00.0: R_000E50_SRBM_STATUS=0x200000C0 Jan 21 19:39:41 thoregon kernel: [ 6364.668226] radeon 0000:07:00.0: GPU reset succeed Jan 21 19:39:41 thoregon kernel: [ 6364.673142] [drm] PCIE GART of 512M enabled (table at 0x0000000000040000).
