You might have more luck with answers to your problems on the hardware
list, and failing that you could ask sos@ regarding metadata problems.
Changing the metadata format between BIOS updates seems pretty scummy
and obviously if FreeBSD expects one format and you have some other
format, it won't work :-( However, I believe the sil3112 has problems
beyond this and is just a bad controller.
Here's a reference from sos@ who wrote the driver and knows what he's
