100% repeatable.

Yes, once they have changed to the bad value, they don't move again that
I've seen (done several trials over the past few days).

I'll test to see if they actually change values, but I can say for
certain that they are still invalid checksum, i.e. once I stop the array
I have to assemble it with -U resync to get it back online. (and it of
course rebuilds)

I'm starting to suspect the card's BIOS; it might either be bad or be
some version which interacts strangely with the sata_sil driver.  I am
going to hunt for a flash update for it soon.

Thanks for the reply!
