I've seen panics with pf(4) for some weeks (see -current's archive for one
report from me).
But at that time I couldn't get a gdb backtrace because of a bug in the
binutils...

The last reports where with -current sources of that time.
Should be the latest rev of nd6.c

BTW: Disabling 'options INET6' fixes the panics as well as
switching back to ipf(4), so I'm using pf(4) now since this morning...
