Public bug reported:
With my linux-generic package at 3.8.0.27.45 I had a lockup while
running eight KVM instances; the soundcard continued to loop the little
tiny sample of audio it was on.
The only lines that made it to /var/log/kern.log:

I've had ten or twelve KVM instances running before, it's a workload I
know works.
I was watching 'top' at the moment of the hang, and I still had over a
gigabyte of cached and over a gigabyte of buffered memory available, so
it wasn't as simple as running out of memory.
Thanks
