I have a 4.2-STABLE machine which had been running fine until a recent
cvsup and make world. The previous version was from around early
December.
FreeBSD 4.2-STABLE #0: Sun Jan 7 23:03:17 SAST 2001
The machine catches a trap 12 now and then, but I seem to be able to
raise the chances significantly by running gimp-1.2 (installed from
ports) - very strange.
I'm running a vinum mirror volume with softupdates _disabled_ on the
vinum volume.
Here's the output from a crash dump:
(kgdb) symbol-file kernel.debug
Reading symbols from kernel.debug...done.

Any ideas?
I've included /var/run/dmesg.boot and my kernel configuration file as
