Bluetooth audio driver causing kernel oops with alsa-driver-hg20070206

Bluetooth audio driver causing kernel oops with alsa-driver-hg20070206

[Allyn, Mark A]

[-- Attachment #1.1: Type: text/plain, Size: 640 bytes --]

Hello:
 
I have tried the snapshot, alsa-driver-hg20070206, on a system running
Red Flag and that has a sigmatel 2202 Codec on the Intel-hda device. The
kernel is 2.6.17.
 
The enclosed dmesg output shows a kernel oops that happened when I tried
to run the alsaconf command. It appears that the problem is in the
snd_bt_sco_volume_get function (which is within the btsco driver). 
 
I am wondering, can this be due to a structure mismatch between the
btsco driver and the Alsa tree? I tried searching for btsco within alsa
and could not find it. 
 
Who is responsible for the btsco audio driver?
 
Thank you
 
Mark Allyn
