Bluetooth device connecting freezes system

[tehpola]

This has happened twice to me since I've updated to Karmic. My system has been kept fully up to date.

I use bluetooth headphones to listen to music on my system. This morning, after bringing my computer back from hibernation, I turned on my headphones. The computer instantly froze up: the mouse wouldn't move and as far as I can tell, it was totally unresponsive (I tried ctrl+alt+f1 and various other key combinations). The last time this happened was exactly the same situation, about a week or two ago; that time I tried sshing into my system and had no response.

I tried finding any sort of information in /var/logs regarding bluetooth but had no luck.

Since I don't know whether this is a bug in the kernel, the bluetooth stack, or userspace (like pulseaudio), it may be helpful to know that I use my headphones with pulse and module-bluetooth-discover. I can provide any pulseaudio configuration if it would be helpful.

This will likely be difficult to reproduce as I have so little information on it, and its only happened to me twice when I've used my headphones practically every day since I've upgraded to Karmic. However, I'd really like to see this resolved because nothing ruins your morning like your system freezing up and needing a cold reboot.

This is my first time using ubuntu-bug, so hopefully all the information required is there, but if not, let me know and I'll post anything required to figure this one out. I appreciate your time and the good work you guys are doing!

This continues to be a sporadic issue. In some instances, my system or my headphones enter a state such that the connection with my headphones is not created. I've even had a total lock up of my n900 once when trying to pair my headphones (they seem to behave similarly: mostly work, but occasional issues). So it seems like its definitely an issue upstream in the kernel since it seemingly affects other distros and even architectures.

Hi tehpola,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 490874

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
