Xorg hangs..., part II
... and it could be Mozilla. At least it happened while I was running Firefox. Then I got this in dmesg:
kernel BUG at mm/rmap.c:483!
There's a sort of stack trace after that. What does one do with that?

Perhaps this has something to do with the flaky behavior of the BIOS when the printer is plugged in over USB. I had to reboot, and the printer was causing trouble. I handn't noticed it was on before.
Here's the full message:
