Package: linux-image-2.6.24-1-amd64
Version: 2.6.24-4
Severity: normal


Freaks out when trying to use my bluetooth headset. Seems to be related
to bug #444603 obviously. It didn't do this with 2.6.22-6.
Kernel log is included below.

What I did is:
*) Set up bluetooth-alsa according to
   http://bluetooth-alsa.sourceforge.net/build.html with alsa device
   types set to "sco"
*) started headsetd
*) tried to "aplay" something
*) entered pin in pin helper app

headsetd then said "unable to open SCO channel to headset: Connection
timed out"

Same behaviour with old snd-bt-sco kernel module and btsco daemon.
