BlueZ 4.60-1 works great and after a week it segfaults and won't start

Giorgio · 04-27-2010, 07:16 AM

Hi all,

I have been using a ARM device with 512MB ram and flash to send messages via Bluetooth to everyone in the proximity. I am doing this with OpenProximity (Python) and it worked for the last week, it did stop for two times but since I didn't have time to find the cause, I just rebooted it (Windows style

) and it worked again, but suddenly it stopped working again last Saturday.

When I did /etc/init.d/bluetooth restart it did not say it failed or something, but when I did /etc/init.d/bluetooth status it said "bluetooth is not running ... failed!".
This is what I got in the syslog:

Code:

Now this is not much help, so I started it manually with "bluetoothd -n -d" and I got a segfault:

Segmentation fault

You'll probably note that the first message is version 4.60 and the second one 4.63, this is because I tried to upgrade, but that did not work completely, but the error above is the same as first before the upgrade.

Don't know if it matters, but I am using Debian Squeeze and the output of uname -a is: Linux debian 2.6.32.2 #1 PREEMPT Fri Dec 18 22:54:28 MST 2009 armv5tel GNU/Linux

Hope someone know how this could happen suddenly, and even better, knows how to fix it

EDIT: Forgot to say, I am using a SENA Parani UD100 Bluetooth USB Adapter which uses the Toshiba Bluetooth stack.

UPDATE: It won't crash until the Bluetooth stick is inserted, so it should be a driver problem?

Anyone? Also tell me please if there's more info needed or if I'm in the wrong forum.

Bluez works again! It seems that it was a sort of kernelmodule incompatibility since it works with another dongle, the one that doesn't work, still works in another computer. How do I find out what module I need for a certain dongle?
