I forgot to point out that I am not running current but FreeBSD topaz 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #13: Sun Feb 26 20:58:16 PST 2006 It also occurs on RELENG_5 but that machine is my gateway and firewall. It may be trying to confuse me but I have to use the NIC in XP before it will panic on the FreeBSD boot. My sacrificial machine only runs 6-stable and it is much harder to make panic. I have 3 280+KB images of the panic and traceback. They are http://owt-207-41-94-232.owt.com/panic-0.jpg panic http://owt-207-41-94-232.owt.com/panic-1.jpg 1st page of trace http://owt-207-41-94-232.owt.com/panic-2.jpg 2nd page of trace This is a 128Kb DSL line on the upload so it won't be fast. Even cropped, the originals were 10MB+. So, they have been made more lossy for size.
