Hi!
I've had the same problem. It seems to be with the new ircomm module.
Dag has been taking a look at it, but from the logs he couldn't see what
was causing this.
The problem occurs when /dev/ircommX is opened, the phone, according to
Dag, gets a speed change command and then for some reason goes silent.
I've tried to modify the kernel code so that the speed change is not to
115200 but to 9600,
but it didn't help.
