[Bug 564270] [NEW] Toshiba NB305 Wireless Crashes when lossing signal to WPA2 PSK network

[Matthew Roy]

Public bug reported:

Using NB305 generates crash reports from kernel loops whenever a WPA2
PSK wireless network signal becomes weak. This may be related to
wireless adapter power-saving features (eg turning off the wireless
adapter)
