Looks like my ath9k AP locked up over the weekend. This is spewing on the console every so often. The tainting comes from a non-wireless related module that is very unlikely to be related to this bug. I had around 200 stations trying to connect, and probably getting resarted every few minutes due to idle timer. BUG: soft lockup - CPU#1 stuck for 22s!
