I have a Logitech Dinovo Edge keyboard which I am able to pair, connect and then use. Every once in a while I get this kernel oops and it drops to text. Its possible to get back to X with Ctrl+Alt+f1 and the C-A-f7. However, the bt keyboard then no longer works. Rebooting the machine results in a hang. The only recourse so far seems to be to hard reboot. --- ApportVersion: 2.9.2-0ubuntu8.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: uv 2336 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=e26f02d0-0462-4873-88bb-9a582b4cfbb8 InstallationDate: Installed on 2013-04-27 (89 days ago) InstallationMedia: Kubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Dell Inc.
