Bug #2311: Xorg crash having something to do with drm

The panel hid and would not come out. I started another panel so that I could continue working. While the browser was loading a webpage, it froze. I switched to my Linux box, which was shelled into my DFly box, with the KVM switch, and found an Xorg.core file, which I copied to /var/crash and tarred. I killed kdm, then logged in. As the session was restoring, the whole machine crashed, but did not dump a kernel core. I uploaded the Xorg core to leaf.

Core was generated by `Xorg'.
Program terminated with signal 6, Aborted.
