Description Jaime Velasco Juan 2011-01-29 02:18:19 UTC
Created attachment 42685 [details] kernel log The computer often locks itself, the panel suddenly loses the image (it sometimes blooms, or get filled with a solid color or a pattern of vertical white and grey stripes). I don't know how to trigger the bug, it can happen anytime, even with an idle system. It has happened to me since I started using KMS, it was stable both with radeonHD and radeon drivers in UMS mode. The frequency of the problem has varied a lot; with the first KMS versions it happened a lot, then it seemed to be fixed with some kernel versions, but reappeared with others... As the problem is random, it can happen after a few minutes of uptime, or after some hours, or not happen at all. At first, I thougth the kernel was completely dead, but I recently found out that I can use SysRq+S and SysRq+T to get some logs. If I try to reboot with SysRq+B the system locks fully and doesn't react to anything, I always have to do a hard reboot. I'll attach lspci, one X log and three differen kernel logs.
