I have a compaq nc8000 and get the same behavior. But not only that. When I'm using the WLAN, I experience random lockups that will only let go if I disable the WLAN (using the WLAN/Bluetooth button on the keyboard).
This is in the release version of Feisty, never happened in Edgy. It may be because of another driver (not madwifi anymore) or the network application running constant background scans? dmesg shows: [ 1367.528000] BUG: soft lockup detected on CPU#0!
