I would be very surprised if the Dell BIOS update changed anything. Actually this bug can now be closed. Good bluetooth work was done in the kernel, which made it into the 3.10 tree. So Ubuntu 13.10 installations won't have this bug.

Unfortunately there is an issue when such input devices are removed: - a battery status report is requested - this fails, because the device is being removed (communications with it are now down) - the failure results in a 5 second wait (the code has a 5 second timeout) - the bluetooth hci code has a race condition: the 5 second delay means one thread definitely loses the race - the race condition leads to devices in the sysfs tree being removed in the wrong order - this leads to udev events being sent out with 'truncated paths' - this leads to userspace programs like Xorg evdev ignoring the event, but then getting confused about what keyboard/mice are actually attached - this results in bluetooth keyboard/mice not working after a suspend/resume (because on resume the input devices are first removed, and then re-added) --- ApportVersion: 2.6.1-0ubuntu9 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: karl 2108 F.... pulseaudio DistroRelease: Ubuntu 12.10 HibernationDevice: RESUME=UUID=a82d4a59-432d-4d4b-9d27-557f669eb637 MachineType: Dell Inc.
