bnep module in 2.6.27 fails to provide bnep0 device

This used to work for me but after some system updates is now broken.

I'm using the following combination on gentoo:

 linux-2.6.27 (64-bit)
 bluez-libs-3.36
 bluez-utils-3.36

Restarting bluetooth, with the usb bluetooth dongle in, gives in the
system log:

[hcid] Bluetooth HCI daemon
[hcid] Parsing /etc/bluetooth/main.conf failed: No such file or directory
[hcid] Starting SDP server
[hcid] Unix socket created: 11

[hcid] HCI dev 0 already up
[hcid] Device hci0 has been added
[hcid] Starting security manager 0
[hcid] Device hci0 has been activated


Then running "pand -c XX" I get:

[pand] Connecting to 00:19:63:14:8C:6C
[hcid] link_key_request (sba=00:10:60:D1:7C:31, dba=00:19:63:14:8C:6C)
[pand] bnep0 connected

[/etc/init.d/net.bnep0] Ensure that you have loaded the correct kernel module for your hardware
[/etc/init.d/net.bnep0] ERROR: net.bnep0 failed to start


It seems pand connects through the bnep0 device, and indeed the mobile
phone i'm connecting to registers the connection and itself connects to
the 3g network, but the kernel complains and the connection is quickly dropped...

I have googled around without any luck at all.
The bnep module is definitely loaded, i have tried reloading it, and
restarting the system. And recompiling the kernel with modules built-in
instead.

I'm quite lost here and hoping anybody can help, or instruct what more
information is required.

ps this was original posted to http://gmane.linux.network which i
presumed, too late, is an advanced development list. I gather this is
the right list as it is the conglomeration of the previous bluez.users
and bluez.devel lists.

Works in 2.6.26, broken in 2.6.27 & 2.6.28 [WAS: Re: bnep module in 2.6.27 fails to provide bnep0 device]

The problem exists the same after an upgrade to kernel-2.6.28

Downgrading to 2.6.26 everything works well.
The same environment is being used so the userspace seems not at fault.

Working on 2.6.26 gives the kernel logging:

Ok, 6 months down the track i lose my phone and buy a new Sony Ericsson
C901. I get the same behaviour but have found by luck a work around.

If i "Browse files on device..." (using gnome's bluetooth-applet) and
connect to my phone (creating a obex connection) then run
pand -c <bdaddr>

everything works fine, and it played well with NetworkManager.


The successful system log looked like:
