>Environment:
NetBSD chapichapo.cimaxonline.fr 5.0.1 NetBSD 5.0.1 (HP) #1: Mon Nov 16 10:13:00 CET 2009  vincent@chapichapo.cimaxonline.fr:/usr/src/obj/sys/arch/i386/compile/HP i386
>Description:
Under some unknown conditions (but it happened twice in a week), ICMP6 crashes the machine. The bug is in m_copym0, called from icmp6_input, and the rest of the stack is ip6_input, ip6_intr, softint_dispatch and Xsoftintr (as far as DDB shows). The reason is a supervisor page fault trap in m_copym0.

The network interface is a sip:

sip0 at pci1 dev 2 function 0: NatSemi DP83815 10/100 Ethernet, rev 00
sip0: interrupting at ioapic0 pin 18
sip0: Ethernet address 00:a0:cc:77:da:46
nsphyter0 at sip0 phy 0: DP83815 10/100 media interface, rev. 1

>How-To-Repeat:
It just happens while pinging (ping6) or trying to fetch some mail through pop3s.

Responsible-Changed-Why:
not related to i386

also, if the issue was indeed in ICMPv6 (and not in the driver), it is
very likely already fixed
