mpt(4) iuCRC errors

[Joshua Boyd]

Just an update. I replaced the drive, and continued to see the same errors.

I reseated the cable for that drive into the backplane, and it appears
that the errors have gone away. ZFS is resilvering the drive now, so
we'll see.

I really should hotglue all of these connectors into the backplane!
