>Description:
I have compiled bridge and pf in kernel. I configure and enable bridge. Then I enable pf with minimal set of rules (block all). After few seconds with really low traffic, kernel panics with following information:

fatal kernel trap (cpu 0):

    trap vector = 0x1e (Unaligned Reference)
    cr.iip      = 0xe000000004104930
    cr.ipsr     = 0x1210080a6018 (ac,mfl,ic,i,dt,dfh,rt,cpl=0,it,ri=1,bn)
    cr.isr      = 0x20400000000 (code=0,vector=0,r,ei=1)
    cr.ifa      = 0xe00000003d03566e
    curthread   = 0xe00000003e700c80
        pid = 12, comm = swi1: net

[thread pid 12 tid 100005 ]
Stopped at      pf_addrcpy+0xa1:        [M1]    ld4 r14=[r33]

I have tried with several different network-drivers.
>How-To-Repeat:
On IA64 hardware, Compile kernel with BRIDGE and pf. Configure and enable bridge. Enable pf and generate some traffic thru bridge.
