>Description:
The system panicked on input from a USB keyboard.
X was running. The system had been idle, so the monitor was off.
I have a habit of hitting Ctrl to make it "wake up"; that's probably
what I did this time, but I'm not certain. It didn't respond, so I
hit a few more keys (Num Lock, Ctrl-Alt-F1, etc). Eventually, I hit
Ctrl-Alt-Delete, and it rebooted. Most likely, the system had just
finished dumping core and rebooted on its own, and the timing was
just a coincidence.
I've been running this setup for nine months, and this is the first
instance of this panic. One might suspect it's a timing issue.
