Hi everyone,

I get a kernel oops on 2.6.32.10 when I use an rt73usb WLAN stick with hostapd 
0.6.10. It's bridged with one of my ethernet (r8169) interfaces. When I have 
the stick plugged in without hostapd, the kernel oops doesn't happen. It's not 
easily triggered, it usually happens within a few hours of use with hostapd. I 
have about a dozen of those from while tracking this bug down, if needed.

Everything seems to work fine (before and after the oops), but at least on one 
occasion I had a large delay on my ssh line when the oops happened.

I have no idea what is causing this, but will happily test any patches that 
are handed in my direction :)

Kernel oops, .config and hostapd.conf are attached. Please tell me if anything 
else is needed to hunt down this bug.

Regards,
Lee
