It's also hard to find because the people buying the 7000-series cards
for use under GNU/Linux finding their new toy doesn't work are
requesting 6000 "downgrades".  After spending a week wrestling with the
7000, we were _refused_ the downgrade option, despite the fact that we
were willing to eat the price difference on the card (7k being rather

The issue appears to be hardware compatibility related.  Our ASUS mobo
(details not immediately available) doesn't like the 7000, or so it
would seem.  It's not listed on 3Ware's compatibility list.  We also

disk and anaconda detection.  Or as identical as we could establish --
linuxiso.org was the cited source, and our md5 sums matched theirs.

FWIW, I also tried the installation under Debian with similar errors.

We're currently downgrading to an 8-port card we're harvesting from
another system, that's known to work.

Our experience with both the card and the company suggest exploring
