I flip to tty19 and get this:

I figure the system is locked hard so I grab my trusty binder and start
writing the oops down. I get about halfway through when suddenly the
system flips over to my syslog console (which I'd tried to switch to with
no response earlier), and I see this come by:

I'm running 2.1.40 with the pre-2.1.41 patch that was posted by Wolfram
Kleff earlier, the ext2 compression patches, and the Pentium memcpy patch.
When the system came back, everything seemed okay.
The system *looks* okay now, though. It seems to be running fine, and at
the very least there are no wacked out values in the "shift-scroll-lock"
kernel readout. I don't know whether that means much of anything, though.
