Title:
Null pointer dereference in drm_debugfs_remove_files
Status in “linux” package in Ubuntu:
Expired
Bug description:
Launching Firefox (from the KDE panel) sporadically causes a kernel Oops
(Null pointer dereference) in drm_debugfs_remove_files (output is attached).
The system continues to run, and after returning to the desktop session by
switching away from the vt and back again, Firefox is actually running.
EDIT: The bug appears since the upgrade to oneiric, both with Firefox
7 and now 8.
