** Description changed: Linux kernels after 3.2 introduced battery status reporting for devices such as bluetooth keyboards and mouse. 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.
