IPF & IPFW & DUMMYNET ,System PANIC

[Deadman-s]

Sorry for my poor english.

I have used a box with router and traffic shaping
Like m0n0wall, I have Build ipfilter in kernel, ipfw and dummynet with modules,
I tested built it on 8.1 and 8.2,but it panic in 100mb fttb, other 2m adsl and 10mb fttb no problem.
Because we build all in the mfsroot, I can't enable coredump..

Please view this image. The console tips : "dummynet: fast io: pkt chain detected!"
Thanks all.

Don't enable 2 firewalls (IPF and IPFW). Use one or the other, not both.

Thank you sir.
But I've found another problem.

The most common cause of these panics are memory errors.
