The top priority is to root cause this, so that we can stop the
problem from happening as fast as possible, and I'm still waiting for
the SHA1 ID that was used for the last kernel Dave booted before the
problem occurred which is pretty damn critical for making forward
progress here.

It could even be some PCI or x86 layer change that caused the corruption,
we don't even know yet.
