Let's wait for the intel and acpi folks. It would be interesting what
the new intel toy says to your BIOS.

Not much because it doesn't know about my processor. About all I could
get out of it is that my MSRs are inconsistent, SMI latency is bad, and
the round-trip latency via MWAIT test gives elapsed time = 285ms with
229 iterations/ms.


Looks like the Toshiba NB305 has an Intel Atom processor in it. bits-327, released today, now detects Intel Atom processors, and no longer shows them as unknown. We don't have any processor-specific tests for Atom yet, though we may add some in the future. All of the general tests should work, however.

Can you provide more details on which MSRs show up as inconsistent on your system? They might represent actual bugs in your BIOS, but we might just need to add a few more entries to the Atom CPU-specific MSR blacklist as expected inconsistencies.
