Here's a "me too" message. AMD Athlon / FreeBSD 6.2-PRERELEASE i386

This works: FreeBSD 6.2-PRERELEASE #0: Thu Dec 14 11:34:36 CET 2006
This doesn't: FreeBSD 6.2-PRERELEASE #0: Sat Dec 30 11:27:11 CET 2006

Between those all that has changed is the source (via cvsup)

Panic messages:

with samba disabled it happens with ntpd:

I'm not sure it that's all that matters, I can supply more information
if needed.
