[Bug 794033] [NEW] bluetoothd randomly dies on Alienware M15x

[Jeff Lane]

Public bug reported:

Binary package hint: bluez

I have an Alienware M15x that is running Natty, upgraded from Maverick,
upgraded from Lucid...

Bluetoothd seems to die at random intervals.  It just quietly goes away
and doesn't generate a crash, so apport doesn't fire to let me know.
Usually this happens after it's sat idle for a while, it never seems to
happen when I'm actually on the machine using it.

The only thing I use bluetooth for is a bluetooth Magic Mouse.  I don't
use it for keyboard or audio.

Here's some info from my system:

This appeared on console while running bluetooth-properties when I discovered the failure this morning:
bladernr at klaatu:~$ bluetooth-properties 
** Message: adding killswitch idx 3 state KILLSWITCH_STATE_UNBLOCKED
** Message: killswitch 3 is KILLSWITCH_STATE_UNBLOCKED
** Message: killswitches state KILLSWITCH_STATE_UNBLOCKED
** Message: killswitch 3 is KILLSWITCH_STATE_UNBLOCKED
** Message: killswitches state KILLSWITCH_STATE_UNBLOCKED
** Message: RFKILL event: idx 3 type 2 (BLUETOOTH) op 2 (CHANGE) soft 0 hard 0

** Message: killswitches state KILLSWITCH_STATE_UNBLOCKED
** Message: killswitch 3 is KILLSWITCH_STATE_UNBLOCKED
** Message: killswitches state KILLSWITCH_STATE_UNBLOCKED

If you look at Syslog, you'll see a series of tracebacks where
bluetoothd dies.

I have to do a full reboot to get bluetooth working again.
