1. It crashes after about 2 hour. I don't know why it crash.
2. Once the AP reboot, after a while the bridge crash.

Comment (by mrenzmann):
1. It looks like you're blindly loading all MadWifi-related modules,
including all rate control modules. This just calls for trouble, and you
should change that. Load Madwifi via {{{modprobe ath_pci}}}, and let
modprobe do the job of resolving the dependancies.
2. You provided an opaque oops dump, which is of not much use to anyone
not working with your system (virtually everyone). Please provide a
"decoded" oops instead, instructions can be found on
[wiki:DevDocs/KernelOops].
