[Regression] Bluetooth pairing does not work anymore in 2.6.39-rc3 (works in 2.6.38.3)

Hello,

I am having problems pairing bluetooth devices in 2.6.39. Scanning
works fine (hcitool scan), but when I try to pair a device using
"bluez-simple-agent hci0 $MAC", I receive the following error message:
"Creating device failed: org.bluez.Error.Failed: Input/output error"

The same command reliably works on a 2.6.38.3 kernel with pretty much
the same config.

According to lsusb, I have a Broadcom Bluetooth Controller with ID
0a5c:217f. I don't see anything related in either of the dmesgs.
My lspci output is here: http://sukzessiv.net/x120e/
Userspace is an up-to-date Ubuntu 11.04 beta (with bluez 4.91).

If there are any debugging steps that I could do or patches to try or
revert, let me know. Unfortunately I can't do a proper bisect since
the machine is a netbook type.

cheers,
gohai
