I have a similar problem but my clients are Linux FC2. When I close
my connection from Linux clients the server has to be rebooted as it
freezes. I also tried shutdown the the following in sequence and the
server also freezes.

ifconfig bnep0 down
ifconfig bnep1 down
brctl delif br0 bnep0
brctl delif bro bnep1
hciconfig hci0 down ................

My server is Fedora Core 2 with kernel-2.6.8.1-mm4. It is
also a bridge-router-firewall (firewall = www.shorewall.net).
I also tried patching my server with patch-2.6.8-mh2 with the
same results. Can anyone help ?

there is no need to have bluez-sdp and bluez-pan installed. Remove them
and only use latest bluez-libs and bluez-utils.

I have re-installed bluez. The setup works well as
before until a client bluetooth is downed or is temporarily
out of range. The server, then freezes with the console
going blank.

I tried using Bluetooth on Windows/XP Professional with the
same results.

Is there an older version of bluez that does not do this ?


Thanks.

I made more tests. I put the results here hoping it
might assist point to the problem.

I found the ff:

1. Installed bluez NAP server on another Linux-2.6.8.1-mm4-mh2
with nobridge-router-nofirewall-bluez. Result: When client
disconnects the server does NOT FREEZE.

2. Installed bluez NAP server on various versions of
Linux-2.6.8.1-mm4-mh1 && mh2; Linux-2.6.8.1-mh1 && mh2 on
bridge-router-firewall-bluez.

When client disconnects the server FREEZES in any combination.

3. Using any setup in item 2, I can disconnect a client without
freezing the server if I disable bluetooth by "rmmod" up till
uhci_hcd at the server first. Then, I reloaded the modules
to restart pand server so I get the client reconnected
successfully.

With these processes, I got the following logs on the server:

I think this is a problem in the Linux bridge code. Please report this
to the bridge mailing list or the netdev mailing list.

Stephen, do you have an idea or a patch for it?

Marcel

linux kernel to compile bluez

[Massimiliano Cuccia]

Hi all
I installed linux suse 9.1 professional
it ships the kernel 2.6.4-52

I can't compile bluez (other message posted to the
users and developer's list), so I'm thinking that the
problem could be the kernel version 

Have I to update the kernel to version 2.6.5-7.108
(from suse archive)?

Or other patch/versions are available?


thanks

(other version of OS)
After I installed Fedora core 2, the bluetooth stuff worked out of the
box. The latest kernel FC2 has is 2.6.8

Also someone there on the list told he installed fresh RedHat9. Not very good
move, unless there were some other important reasons why RH9. RH9 is not
supported by RedHat anymore and most of the rpm-packaging volunteers
has changed to Fedora and "supports" it.

go for the upcoming SuSE Linux 9.2 release, because this will have the
latest Bluetooth kernel and userspace code.
