I think Mario's patch is good overall for the stability. It looks to me
that we are catching some weird state inside firmware where we don't
have direct visibility. Or this is my guess at least.

Used to validate crb_cmd_ready responses.
The patch failed at 201 hours, on the ninth drop into S3. While this
represents an all-time high for uptime, the failure demonstrates that
the Intel PTT can still enter a corrupt state.
Where do we go from here?
