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) @ pci/if_rl.c:1485
2nd 0xc0766280 bridge (bridge) @ net/bridge.c:777
Stack backtrace:
lock order reversal
1st 0xc0768540 ifnet (ifnet) @ net/bridge.c:424
2nd 0xc379307c radix node head (radix node head) @ 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
