As of a buildworld/installworld several hours ago CURRENT is constantly
crashing from underneath me:
[ output from uname -a ]----------
FreeBSD shadowmere.student.utwente.nl 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Mon Jul 10 14:33:42 CEST 2000 daeron@shadowmere.student.utwente.nl:/usr/src/sys/compile/ARSENIC i386
I managed to get one crash-dump (i don't know how to actually debug this
but if someone can give me directions i would like to help out)
i have attached dmesg output, as well as a kgdb-session taken as far as i
could from from the example in the Handbook ...
This has just started happening with this specific CURRENT.

Managers know it must be good because the programmers hate it so much.
