Ath0 Crash the PC

Hi There.
With the debug on in hte kernel "ZABU" I found this when my Atheros card 
crash:

lock order reversal
 1st 0xc36c1e84 rl0 (network driver) _at_ pci/if_rl.c:1485
 2nd 0xc0766280 bridge (bridge) _at_ net/bridge.c:777
Stack backtrace:
lock order reversal
 1st 0xc0768540 ifnet (ifnet) _at_ net/bridge.c:424
 2nd 0xc379307c radix node head (radix node head) _at_ net/route.c:544
Stack backtrace:


looks like is a Bridge problem, I have the option BRIDGE in my kernel 
may be I need try another way to make the bridge work?

any idea.
thanks
