** Description changed:
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.)
