setting sysctl net.inet6.ip6.fw.deny.unknown.extension.headers off crashes R51

[Wolfgang Lausenbart]

Hello List,

Now using FreeBSD 6.0-STABLE.
If I disable net.inet6.ip6.fw.deny_unknown_exthdrs,
then Thinkpad R51 crashes. 
Has this been fixed in HEAD?

using standard "ip6fw allow from any to any" rules...

net.wlan.debug had before set been to 1
then this causes the os to freeze:
sysctl net.inet6.ip6.fw.deny_unknown_exthdrs1->0

any ideas?
