Title:
bluetoothd freezes and cannot be killed
Status in “bluez” package in Ubuntu:
Confirmed
Bug description:
On oneiric, usage of bluetooth is quite problematic for me.
Every now and then, the bluetooth daemon stops working.
1) The bluetooth applet keeps showing a connection
2) System log is filled with some
11400.468174] INFO: task bluetoothd:1941 blocked for more than 120 seconds.
[11400.468190] bluetoothd D 0000000000000001 0 1941 1
0x00000000
3) Trying to restart the bluetooth service is useless
The bluetoothd daemon cannot be killed, even with kill -9
hcidump gives
HCI sniffer - Bluetooth packet analyzer ver 2.1
device: hci0 snap_len: 1028 filter: 0xffffffffffffffff
and hangs.
Bluetooth was (almost) fine in natty.
