Comment 5 for bug 839157

To add some info, with a 3.1.0 kernel, I have BT working on an old thinkpad with karmic and my 3 android phones. I can browse with obex no problems.
With the same 3.1.0 kernel on my now upgraded oneiric laptop (where things used to work with lucid and maverick), I am able to pair with my phones, I have a custom app that's able to talk bluetooth once with my phone, but after that, I see:

connect(4, {sa_family=AF_BLUETOOTH, sa_data="*\177\2037Z<\31\0\0\0\0\0\0\0"}, 10) = -1 ECONNREFUSED
(Connection refused)

And again, phone and laptop are paired, unpairing/repairing works but only helps my app working once, after which it fails (and it used to work just fine with older ubuntus, and still fine with karmic), and browsing with obex fails reliably (while it works with karmic too).
browse files with bluetooth-applet still gives me: Failed to mount OBEX volume: Connection refused for my 3 devices that are otherwise paired fine.
