Some customer Power 6 systems this time last year had problems with
these, but haven't seen it lately.  Every one was running RAID in the
CEC and required the card to be replaced, although if memory serves,
none of them crashed or suffered any degraded performance while
waiting for an outage opportunity to replace.

Played the PTF game with those as well, no help.
