You've got several occurences of the following in the logs:
bluetoothd[25721]: connect(): Connection timed out (110)

I'm pretty sure that's coming for the SCO socket and I recall there being
a related kernel bug which got fixed some time back. You might want to try
with the latest 2.6.30-rc kernel or one of Marcel's git trees (e.g.
bluetooth-testing). Those should have the issue fixed.
