This kernel is quite old. You really should upgrade the kernel...

I had similar problems with a very similar setup.
The problem is that when the bnep0 interface enters the bridge, the bridge's
"mac address" changes. You can see that happening doing a "ifconfig pan0" before
the bnep0 joining the bridge and after, to see the hardware address of the pan0
interface.
I tried to solve this by issuing "arping's" so that other machines on the
network would be warned about the new hardware address, but unfortunately never
got this to work properly... :(
It has been quite a while since i've tried this, though. So maybe in recent
versions the bridging layer doesn't change the hardware address anymore?
If you have better luck than me, please let me know.
