I don't see that we resolved that one... It looks like drm_open is
returning "no such file or directory".  Check the permissions on the drm
device.  That said, it still shouldn't panic,  I'm suspicious that it
may be related to copyin/copyout with locks held.  See if the following
patch still applies cleanly.
