icmp6 LOR on freebsd6-beta2/sparc64

[Peter van Dijk]

Hi,

on my fresh 6.0-BETA2 upgrade (from 5.4), I got (just once) the
following LOR:

Aug 13 15:39:05 onion kernel: lock order reversal
Aug 13 15:39:05 onion kernel: 1st 0xfffff8003377fd68 inp (raw6inp) @ /usr/src/sys/netinet6/icmp6.c:1895

Aug 13 15:39:05 onion kernel: fork_trampoline() at fork_trampoline+0x8

This is in the middle of bootup; dhclient had already ran; I gather
from the messages log that it happened after sysctl.conf was parsed
but before getty tried to open consoles (which didn't work as I forgot
syscons).

peter at onion$ uname -a
FreeBSD onion.home.dataloss.nl 6.0-BETA2 FreeBSD 6.0-BETA2 #1: Fri Aug 12 03:09:54 CEST 2005
peter at onion.home.dataloss.nl:/usr/obj/usr/src/sys/ONION  sparc64

The machine speaks IPv6 on two (vlan) interfaces; no tunnels.

Cheers, Peter
