--- Comment #7 from Pekka Paalanen <[email protected]> 2009-09-14 11:48:01 PST --- >From what has been reported here, this looks like a race in a completely irrelevant (to nouveau) part of the kernel. It happens randomly, more often when nouveau.ko KMS is loaded early, and less often when nouveau.ko loads later. AFAIK no-one has yet managed to hit it completely without Nouveau, which is somewhat concerning. My guess is that nouveau alters the kernel code execution timings and makes a race elsewhere a lot more failure prone. Some suggestions: - search kernel mailing lists for CFQ bug reports (since it seems to happen in CFQ code) - try to reproduce it without nouveau, e.g., try an old FB driver - try enabling heavy debugging features in the kernel config, like kmemcheck or kmemleak I'm trying to steer this away from Nouveau first, because it looks very difficult to debug. In the future, please provide full kernel logs from boot, and set attachment type to text/plain. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
