Description Paul Menzel 2011-10-06 02:06:39 UTC
Created attachment 52032 [details] Photo of monitor displaying Kernel messages like call trace This report is a follow up for my message sent to the mailing list . Unfortunately the Bugzilla instance of Linux  is still down due to the security breach in August and therefore I am reporting this issue here in the FreeDesktop Bugzilla . Having a lot of windows open using the Awesome window manager  the X server crashed printing the following to the monitor. Please see the attached image for the complete message.

Comment 1 Michel Dänzer 2011-10-06 03:28:11 UTC
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.

(In reply to comment #1) > [...] 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.
