Pairing a bluetooth device hangs a computer

[Denys Rtveliashvili]

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.

Now I believe this is something related to IRQ.

When I change the IRQ settings in BIOS from "11" (the factory default) to "Auto" this symptom disappear.

[Andrew Fenn (andrewfenn)]

I am using a Samsung R55 with Ubuntu 8.04 and I am having the same problems. Nothing about IRQ in my BIOS settings.

I just encountered this same kind of lockup today. I have tried 2 different phones in combination with 2 different bluetooth adapters. The lockup only occurs on one of the phones, the HTC Tilt - AT&T 8925 (Win Mobile). The Sony Ericsson (Symbian) phone does not have this problem.

When I initiate bonding from the desktop, no problems. Can connect and browse the device. When I initiate bonding from the HTC Tilt, the system immediately and complete freezes everything.

I tried to catch an error message. I left open two terminal windows, one tailing /var/log/messages and the other tailing /var/log/dmesg and I initiated bonding from the HTC Tilt. It bonded then locked and there were no log messages issued. And when I reboot. There is no record of any errors that I can find.

It doesn't matter what preferences or services I have enabled on the Bluetooth Applet (0.25) the result is the same.

Using Ubuntu Hardy 8.04, kernel 2.6.24-16-generic, gnome 2.22.1 with all latest patches on Athlon machine with 512 MB RAM (non-descript e-machine).

Bluetooth devices: no-name class 1 device and IOgear gbu221 (class 2).

Phones: HTC Tilt - AT&T 8925 (Win Mobile) <- the problem phone and Sony Ericsson (Symbian) <- the no problem phone.

This is NOT a random lockup. It happens every single time I initiate bonding from the HTC Tilt and the lockup occurs immediately after "bonding completed" message displays.

Have the same problem over here...pairing freezes everything and Caps,Num and Scroll lock keep blinking...
Denys Rtveliashvili said something about IRQ, make sense. Maybe Ubuntu/Bluetooth/Linux is trying to use an bad IRQ for pairing? Is there anyway to set which IRQ pairing will use?
Maybe a patch to probe for a proper one?

I get the same problem on a Sony Ericsson C702.

[Alan Hartless (harty83)]

I have this exact problem pairing my compaq presario v3000 and my tilt (htc 8925). I have all the latest updates installed for Hardy. This sucks!

[vikhyath (vikhyath-gmail)]

Exact same problem for me as well. Please let me know what I can do to help solve this bug.

Cellphone: Motorola A1200R
Notebook: Dell Inspiron 9300

[RTSAnime (rtsanime)]

Exact same problem on 2 of my laptops

Cellphone: LG CU720 (tested with both laptops)
Notebook1: Dell Vostro 1400 - Hardy 2.6.24.19-generic
Notebook2: Thinkpad T60p - Hardy 2.6.24.19-generic

[RTSAnime (rtsanime)]

An Update: Initiating pairing from computer seemed to work on my t60p. Phone and computer are now paired no crash:
From bluetooth menu choose browse device.
Select phone.
enter passkey on both.
pairing goes through no crash.

Will try similar procedure on my Vostro later

[RTSAnime (rtsanime)]

Worked for my Vostro as well.

[Simeon Walker (simbloke)]

Same problem with LG KU990 Viewty, pairing initiated from the phone.

Laptop: HP 6510b, Intel chipset, built-in bluetooth
Desktop: Intel DQ35JO motherboard, Belkin USB bluetooth

No problem with other phones: Nokia N95 8GB, Samsun U600, Sony Ericsson K750i.

[vasilis34 (vmanolop)]

Pairing my laptop (Ubuntu Hardy 8.04) with Sony Ericsson C702 makes the cellphone restart. I have tried all the different combination such as initiating the pairing from the laptop or the phone but always the same problem.

[Jamie Bullock (jamie-postlude)]

Same problem here:

Ubuntu Hardy 8.04, Ericsson C902

Initiating pairing from phone crashes the laptop
Initiating pairing from the laptop causes a soft reboot of the phone

However, pairing works fine with other phones e.g. Ericsson w810i

[Lembitu Ling (snakeman)]

Confirmed pairing with SE C702 crashes cellphone (soft reboot).

ThinkPad R61i & Sony Ericsson C702

Ubuntu 8.04: mouse cursor is frozen, keyboard does not work and the "caps lock" indicator is blinking.

Ubuntu 8.10: soft reboot of cell phone.

[rudinger (vjorda)]

Standard PC & Sony Ericsson V640i

Ubuntu 8.04: mouse cursor is frozen, keyboard doesnt work and the caps lock indicator is blinking.
Ubuntu 8.10: it works fine.

[Florian Demmer (fdemmer)]

MSI BlueToe & SE C702, 8.10

strangely this has worked yesterday. i could browse files via nautilus and send files from phone to pc.
today browsing causes a reboot of the phone and the pc is not found when trying to send files.

pairing goes through (initiated from pc, enter passcode, success, ...), but then again reboots or pc not found.

in case it's due to a recent update my updates from yesterday evening (after it had worked):

OS: Ubuntu Hardy 8.04 64-bit
Cell Phone: LG CU515
BT Adapter: CompUSA Bluetooth adapter P/N: UBTBR1E-N-WWM S/N: 05092701361

Trying to pair my phone, and immediately after I enter the PIN # or freezes the machine, leaving all the blue LEDs on my computer blinking like a retarded display in a retail store.

I really hope there is a fix for this, because I hate to have to reboot into vista just to copy photos from my phone.

[vikhyath (vikhyath-gmail)]

any updates on this bug? Is it fixed in Jaunty?

The same problem with 8.04 and
2.6.24-24-generic #1 SMP Wed Apr 15 15:11:35 UTC 2009 x86_64 GNU/Linux

and wm5 mobile phone
Is there fix?

[Josiah Yoder (yoder2)]

I had a similar problem the second time I tried to connect to my phone. Every time I typed the four-digit pin on both the phone and the computer, it would connect and then immediately hang. I ended up not connecting with the bluetooth panel applet, and proceeding straight to the following commands. Perhaps it is somehow still connected despite rebooting?

#!/bin/sh
ADDRESS=00:19:A0:A2:70:55
sudo hcitool cc $ADDRESS &&
sudo hcitool auth $ADDRESS &&
( sudo rfcomm connect 0 $ADDRESS 16 </dev/null >/dev/null & )
sleep 2
sudo chmod 666 /dev/rfcomm0

which worked, even though it was a bit finicky.
