Would it be possible for you to test the Oneiric kernel, to see if the issue exists there as well:

https://launchpad.net/~canonical-kernel-team/+archive/ppa/+build/3211482

[Lars Noodén (larsnooden)]

Does testing the Oneiric kernel involve just pulling in the kernel package and installing it? Or must I install Oneric first?

[Brad Figg (brad-figg)]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Lars Noodén (larsnooden)]

This lockup hasn't happened now for a while, so it seems to have been fixed.

I forgot to say, it's happened using:

linux-image-3.2.0-24-generic
and
linux-image-3.2.0-25-generic

either within xen or without (booting directly the kernel)

[Ovidiu-Florin BOGDAN (ovidiu-florin)]

this still hapenes with 3.2.0-39-generic.

[Mikko Rantalainen (mira)]

I've hit this multiple times during last week. The cause for me might be either graphics adapter driver (i915) or VirtualBox kernel driver (vbox*). Here's a portion of /var/log/kern.log (hostname replaced with "localhost"):
