System: FreeBSD helium.verweg.com 7.1-STABLE FreeBSD 7.1-STABLE #58: Tue Mar 17 14:39:08 CET 2009 root@helium.verweg.com:/usr/obj/usr/cvsup/7-stable/src/sys/HELIUM-SMP i386
>Description:
Still having WITNESS enabled since kern/132404 I've spotted the following ifnet
related LOR's during bootup. the pf related one is also visible in that pr.
Same configuration applies to the system, sources are of Tue Mar 17 15:43:48
CET 2009
If required, I can generate a textdump of this state.
