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

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

[Gottfried Haider]

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

I'm wondering if you are hitting what I was hitting a few days ago.. the 
commit below got things working over here:
(not sure if this is in the stable yet)
http://git.kernel.org/?p=linux/kernel/git/padovan/bluetooth-next-2.6.git;a=commitdiff;h=b99faf1b798d6d0e33526fd2cef55a405c08ff09;hp=58b6e124aac64bebb2e9e1a136cbd21a5ab0485a

hope this helps,

I checked: I have this commit in -rc3, so it must be something else here.

greetings,

hmm... seems to be working over here with the latest Mainline. one thing 
  I have notice though is the daemon is not starting during 
boot(systemd), manually starting bluetoothd gets me to connect.(system 
is fedora 15).

It was my fault after all:

I had based my kernel config on 2.6.39-rc2 from Ubuntu's
mainline-kernel PPA, and this doesn't have BT_L2CAP..

Case closed.


I am just wondering: is it possible to make BT_L2CAP (and SCO?)
default to yes when BT is compiled in or build as a module?

>From commit 6427451: "The L2CAP layer is needed by almost all
Bluetooth protocols and profiles. There isn't any real use case
without having L2CAP loaded." Yet when I am doing oldconfig from a
config that had L2CAP build as a module, I am getting these easily
overlooked lines:

L2CAP protocol support (BT_L2CAP) [N/y/?] (NEW)
SCO links support (BT_SCO) [N/y/?] (NEW)


cheers,

tweaking the kconfig can do this.

I guess strace of the pairing attempt would be helpful.
