re: port-sparc/40629: kernel panic under high network load using pf (and ipv6)

[matthew green <mrg%eterna.com.au@localhost>]

can you build a kernel with DDB and make sure ddb.onpanic is set to 1?
also, please build the kernel with:

        makeoptions DEBUG="-g"

going on your crash point, it is somewhere in pf_modulate_sack().

perhaps try disabling net.inet.tcp.sack.enable and the
inet6 version of the same.
