I upgraded to the new kernel. At this point it does appear that the fix
in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1346917 has
addressed the issue; I've been running now for ~38 hrs on that kernel
with no issues.

Marking the bug as a dup of 1346917. If something changes (note: the
problem has always manifested itself faster than this before) - I'll
note that.

Title:
  [Supermicro X9DR3-F] Virtual machines hang in kernel 3.13

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Multi-cpu systems are experiencing guest kernels hanging/crashing
  (both windows & linux guests) in kernel 3.13. (Windows guests are
  getting bluescreens, linux guests just seem to be locking up).

  Downgrading to 3.12 eliminates the problem.
