It was a Marvell 9125 AHCI card (highpoint branded), and I've had
numerous problems with them locking up (the 9123s are worse), and have
scrapped all of the Marvell 9123s already, and gone back to using a
combination of Marvell's 88SX7042 (non-AHCI) cards, and Silicon Image
3132 etc. cards.

It's a shame, as Marvell's AHCI cards are readily available, cheap and
do both 6G SATA, and PCIe 2.0, whereas the earlier Marvell cards, and
the Silicon Image cards are all 3G SATA and (more importantly for me)
PCIe 1.0, which ends up being a bottle neck for modern spinning disks...

I wish Intel, Silicon Image (or someone else) would make a reliable SATA
PCIe 2.0 card!

Intel and Silicon Image publish their errata, whereas Marvell keep
their's secret, under NDA, and don't respond to hardware bug reports in
my experience.  Avoid.
