Comment:
I'm running an IA32 system with 2.6.16 and desktop (ie voluntary)
preemption.
I have found the changes in spin_locks-20050331.diff to eliminate the oops
I was seeing when the interface is up - I have seen the AR5212 chip lockup
and reset (below) a number of times, but the host system is rock-solid:

My kernel has debug features enabled and I have a serial connection for
harvesting a clean backtrace - I'll test for the bringup/teardown oops I
was seeing in the unpatched code and post my results in the next day. Oh,
I'll jackup the SSID broadcast rate to check for another race in the
unpatched code too.
