System: NetBSD vr.l.nxs.se 2.0_BETA NetBSD 2.0_BETA (HUMMEL) #0: Sun Apr 18 20:48:43 CEST 2004 lha@nutcracker.stacken.kth.se:/sources/netbsd/2-0/i386/kernel/HUMMEL i386
Architecture: i386
Machine: i386
>Description:
machine sitting at home have started to crash now and then
after I updated it to 2.0_BETA
the machine have IPF configured but not IPSEC configured.
the first time in hang in a thight loop inside kame ipsec
somewhere
I use "plenty" of IPv6 on the machine, in fact, most traffic
is ipv6.
I'll let it crash a couple of more times, and after that I'll
turn of IPF and see if it goes away.
I have kernel built with debug symbols
