Package: bluez
Version: 4.66-3
Severity: normal
rfcomm crashes with kernel bug (see dmesg trace below).
Needs reboot to clear situation.
Post crash the rfcomm process hangs and cannot be killed.
I tried kill <pid>, kill -9 <pid>.
No more rfcomm connections can be made. Further "rfcomm connect X"
create hung processes as well.
rfcomm is called from a bash script (fetch-s0), stripped down:
while [ 1 ]; do
rfcomm connect 0 &
sleep 5
if [ -c "/dev/rfcomm0" ]; then
stty -F /dev/rfcomm0 115200 raw
echo command > /dev/rfcomm0
read -t 1 response < /dev/rfcomm0
fi
rfcomm release 0
sleep 100
done
The loop executes successfully for a few times, then it crashes.

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.0 / Wheezy with a severity
less than important.
We don't have the ressources to reproduce the complete backlog of all older
kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with
Debian Wheezy
