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

I trying now with a diferent PC to see what happend.
I hope this infromation help, pls tell me if you need more information
Yes the information (especially dmesg) helps.
Build your kernel with DDB, INVARIANTS, and WITNESS and -g. When you get a panic collect a stack trace from the ddb prompt and, if possible, a crash dump. Also, if you have an 11a AP try using this machine as a station and load the network with tools like netperf and see if you crash.. Also, if you have different NIC's, try replacing the RealTek with something else. I typically use fxp or em devices with an Intel Pro/1000 my favorite NIC.
Finally, I notice you have ipfw+divert configured. I don't know if it is being used but if so remove it. In general try to reduce the system configuration to the minimum you need to run tests.
Attached is a typicaly kernel configuration I use for debugging. I'm providing it solely so you can see how to enable the stuff above.
