Created attachment 153761 [details] dmesg after GUI freezes up Several times per week, attempting to play a video through XBMC causes the entire X session to freeze upon starting the playback. The last known state of the GUI is frozen on the screen with no evidence of video playback. The bug is inconsistent to trigger in that there is not a particular video file that causes crash. Rather, it seems to happen randomly. After the crash, connecting via ssh is possible, but the system will not go down on its own. The only way to recover is to reset the machine via the hardware switch. Attached is the entire dmesg output. The crash started at 19817.84 with the line, "BUG: unable to handle kernel NULL pointer dereference at 0000000000000008." I am glad to provide additional details upon request.
