In the -CURRENT list I've been told that the new driver was introduced into
8-STABLE at revision 230921.
I reverted to that revision but the problem was still apparent.

So I've now tried:

- Previous BIOS
- Updating the controller firmware from phase 7 to phase 11
- Going back to the old (pre LSI authored) mps driver

But all to no avail.

What has worked is to move the single SATA 3 (6 Gbps) drive (the other 7
drives are SATA 2) to the onboard SATA 2 Intel controller.

So it seems that both the old and new mps driver have a problem with the
Western Digital WD20EARX SATA 3 drive on a SuperMicro AOC-USAS2-L8i (SAS
6G) controller (flashed with -IT firmware).

I'll continue this in the -CURRENT list in the thread about the new driver
as that's where the main discussion has been.
