This report is a follow up for my message sent to the mailing list [1].

Unfortunately the Bugzilla instance of Linux [2] is still down due to the
security breach in August and therefore I am reporting this issue here in the
FreeDesktop Bugzilla [3].

Having a lot of windows open using the Awesome window manager [4] the X server
crashed printing the following to the monitor. Please see the attached image
for the complete message.

Unfortunately for debugging this issue this is the first time it happened and
the issue is not reproducible.

Debian Wheezy/testing is running on this system with Linux 3.0.0-3 [5] and the
(non-free) firmware for the graphics card.

There is no direct evidence that this is related to drm/radeon. The oops
happens in the shmdt system call, most likely called by the X server MIT-SHM
extension code.

Unless you can also reproduce an oops with the MIT-SHM extension disabled (add
-extension MIT-SHM to the X server command line, verify with xdpyinfo|grep
SHM), I'm afraid you'll have to report it to the kernel bugzilla or maybe the
linux-kernel mailing list for now.

Or against the Debian kernel package.

I can’t remember having seen this, so I close this as invalid.
