Bug Description
I've had sporadic freezes on this system before since upgrading to Precise, but I haven't had the resources to try and ssh in prior to this, so I can't tell if this has occurred before. Now that I have an additional laptop I can hopefully catch this again if it occurs.
I screwed up with the logs first, but then managed to salvage dmesg with a Trace from terminal buffer. I'll attach it separately below.
I wasn't active on the desktop when the freeze happened (had my hands on the laptop). At least Chromium, Transmission and Google Music were running at the time.
(I'm not familiar with Traces so I'll just pick something from the first line as title. Feel free to change it if needed.)

I can't tell if you can see it from the Apport-attached files, so I'll add that I'm running Unity 2D here.
