Created attachment 30104 [details] Kernel log I've got this BUG twice in the last couple of days. I'm running the latest git kernel (rc3), xf86-video-ati, mesa and libdrm. This happens in KMS mode in the middle of the night. After the BUG happens the machine kept running and it is only in the morning, when I exit the screensaver, that the machine hangs.
