ath(4) panic: bus_dmamap_load_sg: no mbuf packet header!

[Pawel Jakub Dawidek]

Hi.

I configured NAT (using pf(4)) on my laptop:

MacOSX (Tiger) <-----> ath0[my laptop]bge0 <-----> local machine

When I started downloading few files on Mac from "local machine" via FTP
in parallel I got this panic after few minutes (I was able to reproduce it):

panic: bus_dmamap_load_sg: no mbuf packet header!

And the backtrace:

panic()
bus_dmamap_load_sg()+0x2a
ath_start()+0x2ae
taskqueue_run()+0xaf
taskqueue_swi_run()+0x13
ithread_loop()
...

Any ideas?
