I wonder if you can recreate this with 2.6.34? Or 2.6.35-rc1 (or later)? Unfortunately this is double fault.
First problem is a corrupted assignment to AP inside ATH5k. I did a desperate loop that attempted to connect to AP many times.
And a second problem is a crash in a kernel.
When the first problem gets fixed, second one might be hidden.

I have re-created this issue with 2.6.34 kernel and compat-wireless-2010-06-13. So it means that this bug is still present. =========================================================================== Jun 19 10:37:31 dvouramenna kernel: [335515.969962] ------------[ cut here ]------------ Jun 19 10:37:31 dvouramenna kernel: [335515.970015] kernel BUG at kernel/workqueue.c:302!
