Description:
After one of the udpates (can't say for sure, cause I've done plenty of them and haven't noticed an issue at once) Apple Magic Trackpad connected with bluez4 using bcm2045 based dongle stopped working.

Reconnection attempts are usually unsuccessful: device seems to be paired and connected, though nothing happens.
dmesg shows
[code]
[ 2321.231905] Bluetooth: Frame is too short (len 1)
[ 2395.461838] Bluetooth: hci0 corrupted ACL packet
[ 2395.461855] Bluetooth: hci0 ACL packet for unknown connection handle 16
[/code]
When reconnection attempt is succesfull, system gets stuck in several seconds after connection is established due to kernel panic.

Also tried bluez5, device just shown as paired and connected in bluetoothctl, though nothing works and same entries in dmesg appear.

Additional info:
* package version(s)
linux 3.11.6-1
bluez4 4.101-3
bluez-firmware 1.2-7

Steps to reproduce:
* perform several disconnect/connect cycles until connection is eventually established
This task depends upon
