making H5550+bluetooth more stable, some interesting observations

Hello,

like many others I have struggled with
bluetooth on the h5550.

Bluetooth seems to be even more unstable when the machine
is under load. I found that
running hciattach with realtime prioritiy (SCHED_RR scheduling policy) makes
bluetooth usable. That was with bluez-utils 2.3rel-hh9 and kernel hh36.

My favourite bluetooth restart script:

#!/bin/sh
/etc/init.d/hcid stop
sleep 3
hciconfig hci0 down
sleep 3
killall hciattach
sleep 3
rr-enable /etc/bluetooth/hciattach &
sleep 3
hciconfig hci0 up
sleep 3
/etc/init.d/hcid start

Perhaps that is somehow useful for someone.

Greetings
Andreas Kemnade
