        System      : OpenBSD 3.0
        Architecture: OpenBSD.i386
        Machine     : i386
>Description:
my machine has crashed four (five and now six as i was writing this) times 
in the past hour with a varying amount of time between crashes. i have made 
no recent changes to my system. i am running -current as of Nov 17 or so, 
and a GENERIC kernel.

these crashes have appeared suddenly, the first came as i was not using the 
machine interactively at all. it's not clear to me where these crashes may 
be coming from; maybe a problem with my ethernet cards? i see "fxp" there, 
and both my nics are fxps.

i have disabled various daemons to see if they were the cause, as i had 
samba, krb5, route6d, and rtadvd running amongst others.

what other info may i supply?

here is the trace/where output from three of the crashes:
