The SAS 2008 chip (SAS 6G) is the one that the FreeBSD mps driver has
problems with when used with port expanders. It's the older SAS 3G chip
that works OK with FreeBSD I think.
I had crossed some wires earlier on in our discussion.
We do have a SAS 2008 chip in the system already, but it's

Can you connect an enclosure to the SAS 2008 chip card you have now
and test? I thought I had read about problems like yours with that
chip on FreeBSD when using such enclosures.
The SAS 2008 chip we have is built in to the motherboard; it does not have any
external connectors.
I don't know what's out there having chosen only one such card for
home use. So you'll need to do your own research. Start with looking
at any card with the right chip and then look for evidence that people
have used said card with FreeBSD.
LSI has the SAS 9200-8e, which is based on the SAS

I'm not sure what cards you can get now with the LSI 1068E chip. As
LSI branded cards cost more, I went for for the LSI SAS2008 based
Supermicro AOC-USAS2-L8i as I new I wasn't going to use port expanders.
It could be hard to get cards with the older chip now (you might have
to get something

Advice is:
Use -STABLE and not -RELEASE
Upgrade firmware
Avoid port multipliers

If not, look at paying a small (say $1k) bounty to get it fixed. :)
Unfortunately, our budget situation would not allow this sort of thing right
now. :\ Buying hardware is a lot easier than paying for something like this.
Helping to fix the driver is a thing that Tim is in the unusual

As I mentioned earlier, I was looking around on the LSI site and they have
