Thanks for testing and providing this information.
I see that CONFIG_LOCKUP_DETECTOR is enabled in Precise(12.04) and Quantal(12.10) as well as Raring(13.04). Do you also see this bug on those releases?
However, I do see that Raring is the only release that has CONFIG_HARDLOCKUP_DETECTOR enabled.
I'll build a Raring test kernel with CONFIG_HARDLOCKUP_DETECTOR disabled and post a link to it.
