>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.
