Maarten, Sorry for the delay! On Sun, Jun 09, 2013 at 08:58:44AM +0200, Maarten Lankhorst wrote: > Hey, > > Op 06-06-13 09:28, Fengguang Wu schreef: > > Hi Maarten, > > > > Thanks for the patch!

Booted 1000 kernels with the patch, I no longer see the mutex_trylock() warning. However there is one single occurrence of this warning. Not sure how relevant it is.

At that point I no longer trust anything to be sane. I don't know much about the panic handling in drm, but it's definitely not related to your original issue.

The locking in the current drm panic handler is pretty much terminally broken. At best we're trying not too flood dmesg too badly when it happens. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
