[Bug 211157] [NEW] Pairing a bluetooth device hangs a computer

[Launchpad Bug Tracker]

I have tried to install Ubuntu 8.04 before the release and here is a
problem I see: pairing my phone via bluetooth hangs the computer
completely.

The bug reproduces every time I do the following:

- I try to pair my phone (NEC e949) to my computer, pairing is initiated from the phone.
- Phone asks for a PIN and I tell it "1234"
- Computer says "Pairing request.."
- I click "Enter passkey" and enter the same PIN in the dialog. And I press "OK"
- Ubuntu says "Created bonding ..."

After that the mouse cursor is frozen, keyboard does not work and the
"caps lock" indicator is blinking.

Hardware: Lenovo Thinkpad T61.

Note: This bug reproduces only on an installed Ubuntu 8.04 with all the
patches installed. The LiveCD works just fine.

I would be happy to do more research into this but at this point of time
I do not know what can be done. The /var/log/messages does not show
anything interesting. Perhaps, that's because the computer freezes so
quickly that the messages do not get onto disk. By the way, there are
numerous messages about transactions being replayed during the
ReiserFS's file system check.

I suspect that the problem can be caused either by one of the software
updates or a conflict of drivers. The LiveCD obviously does not have
nVidia's proprietary driver and there can be other differences too.

One more thing. There is a bug #103365 which looks a bit similar. The
difference is that in my case the computer hangs exactly after the
pairing.
