Works for a few seconds
Non Network Manager related components work as exprected:
running the following gets the connection running flawlessly:
pand --conncect BTADDRESS -n
This is a kernel driver and/or Bluez issue and possibly related to crappy hardware (which is still a kernel driver issue), not an NM issue.

If you read the Additional info section, you will see that I already nailed it on NetworkManager.
I have the same issue on Fedora 13. Starting the network with "pand" works. If I start it from NetworkManager the network goes down after a few seconds with the same messages as in the inital report.
How is this a kernel bug when pand works and NetworkManager does not? If the hardware is "crappy" it should not work in either case.
This actually was a bug in NM, and was fixed in early May.
