Comment 2 for bug 289356

This happens for me as well, exactly the same. I had to put the ath9k driver in the modules blacklist in order to go a full day without a crash. As far as I can tell from the information on the web it looks like there is a problem with the 2.6.27 kernel and the ath9k driver that is causing a memory leak when in use.

Not sure if it is related but I can not connect to a Airport Express Wireless N device with WPA2 Personal security. Keeps giving me back a password prompt with a long series of numbers and letters in the password box :(
