Someone just suggested to me (by their own admission on a hunch) that a
microcode update might help with this sort of issue. That probably means
updating to the latest BIOS as a first step (which will probably include
a microcode update), then if that doesn't help messing around with the
runtime microcode update tools (since there will undoubtedly be
something newer than what the BIOS contains).
