Description Ben Gamari 2008-12-10 11:21:55 UTC 
GEM intermittently causes the kernel to go into deadlock. While this has happened several times, I've only managed to get a single backtrack as this requires a serial console. The kernel is apparently racing between two spin locks in the file system subsystem. Eventually the soft lockup watchdog notices the deadlock and dumps out a backtrace.

With the leak fix, I'll be interested to know if this happens any more.
Comment 3 Ben Gamari 2009-01-12 14:07:32 UTC 
I haven't seen this recently. Do you think we should call it fixed?
Comment 4 Jesse Barnes 2009-01-12 15:20:11 UTC 
I guess we can take that as confirmation. :)  Thanks Ben.
