The current 2.6.16.xx sata_mv drivers is known buggy.
Don't rely on it for anything important.

The attached patch is an untested backport of the latest sata_mv,
which should be more reliable than what you've been using.

If you could give it a try and report back,
it would help advance things a bit.
