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.
Comment 3 Peter Svensson 2010-07-24 10:26:02 UTC 
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.
Comment 4 Chuck Ebbert 2010-07-24 14:59:31 UTC 
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.
Comment 5 Dan Williams 2010-08-17 16:34:04 UTC 
This actually was a bug in NM, and was fixed in early May.
