It's happened again doing the same thing. I've installed a newer kernel with
the debugging options following Kris Kennaway's advice. The new kernel (which I
compiled a while ago but never installed) is:
FreeBSD number6.magda.ca 4.9-STABLE FreeBSD 4.9-STABLE #3: Wed Mar 17 16:24:30
EST 2004 dave<at>number6.magda.ca:/usr/obj/usr/src/sys/MYKERNELE i386
Here's the output of starting gdb and of running 'bt':
number6:/usr/obj/usr/src/sys/MYKERNELE# gdb -k kernel.debug /var/crash/vmcore.6

Again, this was a result of running star 1.4.3 to backup my /home onto DDS3
tapes. The tapes are kind of old so I though I'd run one more backup on them
for archival purposes before putting in new ones.
Anything else I can do to help things out?
