[Pkg-bluetooth-maintainers] Bug#531976: bluez: Occasionally the kernel freezes while connecting bluetooth mouse

[George Kiagiadakis]

Package: bluez
Version: 4.40-2
Severity: critical
Justification: breaks the whole system

Hi,

I have a logitech bluetooth mouse which I connect using hidd --connect $MAC_ADDRESS.
Before I upgrade to bluez 4.40 in unstable, it had always been working fine.
Since I upgraded to bluez 4.40, I am experiencing strange behavior and
occasional kernel freezes.

My usage scenario is this:
First I turn on the mouse and then I run a script on a console, which runs
"sudo hidd --connect $MAC_ADDRESS", to connect the mouse.
When I want to disconnect it, I simply turn off the mouse.

Before the bluez 4.40 upgrade I had no problems with that. Since 4.40 though,
every time I run this script, I first get an error message saying "No route to host"
and then I have to try once again and the mouse connects fine. Sometimes though,
the second time it does not succeed either, and hidd does not return.
After a few seconds, the kernel freezes completely. Keyboard/screen are dead
and I can't ping the machine. Only alt+sysrq+b works, which reboots the machine.

This has happened to me twice, one time with a custom 2.6.27 kernel and the second
time with debian's 2.6.29-2 kernel. The logs don't write anything about it.
Ask me if you need any further information.

Regards,
George
