kern/121955: [ipfw] [panic] freebsd 7.0 panic with mpd

[Alexander Shulikov]

After I set net.isr.direct=0 and others:
net.inet.ip.fw.one_pass=0
net.inet.ip.fw.autoinc_step=1
net.isr.direct=0
net.inet.ip.intr_queue_maxlen=1024
net.inet.ip.dummynet.hash_size=256
net.inet.ip.dummynet.expire=0
net.inet.ip.dummynet.max_chain_len=64
net.graph.maxdgram=128000
net.graph.recvspace=128000
net.inet.tcp.sendspace=131070
net.inet.tcp.recvspace=131070
kern.ipc.somaxconn=8192
kern.ipc.maxsockbuf=2097152
server panic after 10-15 minutes, against 3-5.
But in kernel dump now:

Previous frame inner to this frame (corrupt stack?)

In ipfw I use tables, that then added to pipe, that configured with mask 0xffffffff.
I have similar server with load much smaller under FreeBSD 7.0-RC3, but with similar configuration (used ipfw+tables+pipes, pf, mpd5), but in mpd I don't using ng_car. May be using ng_car and dummynet together is corrupt?
