n900 reboots after auto connect bluetooth
 

i am encountering a rather big problem. i bought a bluetooth steeringwheel remote for my n900. when it is not set to automatically and i do a manual connect everything works perfect. but when selected as trusted device and connected on powering up the remote the n900 shows it is connected and then it reboots....

does anyone know what could cause this problem? when i do the same thing on my nokia X6 it works perfect. so it must be a problem in the n900 or the new custom firmware.
