Public bug reported:

I have a laptop and keyboard plugged into my Ubuntu desktop PC.  I have
Synergy installed on this PC and a laptop so that I can use the same
keyboard an mouse on both.  While I was working on my laptop I heard the
HDD of the PC grind up then saw the Ubuntu machine drop out to the login
screen.

As you can see from the above I am running a very recent Kernel image.
This was to diagnose if Bug #1453029 was present in the latest Kernel or
not (happily the answer seems to be that it is not).  I have manually
report this bug because it happened at the same time as Bug #1477566 so
the details from one might be helpful for the other.
