I got my first oops ever when upgrading from .24 to .25 :-( Just after
rebooting I was using the console in text mode (which I almost never
do, I'm always in X) when the machine apparently froze. This happened
twice. A third lockup happened, and this time I noticed that the mouse
still worked, though I could do no console switches. I logged in from
the net, everything looked normal but I couldn't reboot, and finally
had to do a hard reset :-(. Here's the output of the first oops. I ran
it in another machine, but ksymoops segfaults at the end!

Using `System.map-2.0.25' to map addresses to symbols.

I hope I did the reporting right...
