Hi all,
Earlier today I suffered a kernel panic while the system was coming back up
from "shutdown -r now".
This is an SMP system running 4.6-PRERELEASE from May 1st. Here's uname -a :
FreeBSD rhadamanth.private.submonkey.net 4.6-PRERELEASE FreeBSD 4.6-PRERELEASE #0: Wed May 1 21:59:38 BST 2002 setantae@rhadamanth.private.submonkey.net:/usr/obj/usr/src/sys/RHADAMANTH i386
Attached is the output from a script session of gdb; I tried following Michael
Lucas' hints from Big Scary Daemons, but it seems to have hit a bit of a dead
end.
Also attached is the output of dmesg.
Any further information can be provided if you give me instructions on how to
get it.
Thanks,
Ceri
