System: NetBSD beefcake.babymeat.com 1.6Q NetBSD 1.6Q (BEEFCAKE) #31: Mon Apr 7 01:28:01 PDT 2003 dogcow@beefcake.babymeat.com:/usr/src/sys/arch/i386/compile/BEEFCAKE i386
Architecture: i386
Machine: i386
>Description:

the panic happened when I was attempting to fg a backgrounded pthreads-using
xmms. I can upload the core somewhere if need be.

>How-To-Repeat:
You can often cause a reboot by doing this:
phoenix (or some other pthreads-using program)
^Z
fg
