Subject:   FreeBSD 9 on an AMD64 with an LSI SAS controller

Greetings all,

Roughly a week ago I sent to this mailing list a question about
problems with installing FreeBSD 9 on an AMD64 system.
It seems that I now know the reason why booting from the install CD
failed. When buying the system I had not paid enough attention to
the fact that the SAS controller on the motherboard is a new LSI
SAS2008-IR which would need the mps driver. I had been assuming
that since there is an LSI controller on the motherboard the older
mpt driver should work.
The mps driver, which would be needed for the SAS2008 series is
still relatively new work in progress, is apparently not part of
the GENERIC kernel used for the install kits.

The next obvious question in my mind is: "Are these new SAS2008
series controllers now becoming common as the default SAS chips
on motherboards?"
If so, until the mps driver matures enough it might be better for
everybody to check before selecting a motherboard that the SAS
controller on it will work with the older mpt driver.
