OK thanks. Just for clarify Intel state that for that particular erratum "no functional failures have been seen due to this issue" - "Status: No Plan To Fix". Are you saying there are functional failures and it will have to be fixed?

I've not heard of anyone having stuttering problems with the 510. You say that the 510 stuttered on 15 different occasions resulting in an unsafe shutdown count being recorded each time by SMART? That is repeatable on all P67, Z68, and H67 boards?
