I've now had yet another crash under FreeBSD 5.1 (RELENG_5_1, cvsupped 5-6
days ago) and it looks almost the same as the crash I posted about
yesterday (or was it the day before?
Here's some output from DDB:

I tried creating a crash dump by issuing the commands "panic" and then
"continue" but everything seemingly stopped then and nothing was dumped to
disk.
Can anyone suggest what I do next to find out about this crash?
