The new release detects the Atom processor okay, but in bits-327 the
system resets during the SMI frequency/latency test, whereas it didn't
with bits-316.

Here's what it says:

  (MSR 0x39 consistent): FAIL
  (MSR 0x199 consistent): FAIL
  (MSR 0x1a0 consistent): FAIL
  Summary: 7917 passed, 3 failed

I have 3 systems with this same processor, and they all report the same
thing here.
