Seems to me like the best solution is to boykott Adaptec like OpenBSD did.
Actually, based on the thread going on on -stable right now, from ppl that
are talking to Adaptec, the issue is that the cards that use the iir(4)
driver, at least as far as I'm reading things, are no longer considered
supported ... Adaptec / ICP Vortex *is* coming out with newer cards, that
will be supported by FreeBSD, but they won't fall under the iir(4) driver
...
So the problem is more 'older cards with newer operating system' ...

'k, I finally got ahold of someone @ adaptec, and the official word seems
to be:
"FreeBSD 6 is not officially supported for the "GDT" based ICP RAID
controllers. Nevertheless the inbox driver should work."
Great, well, the inbox driver doesn't work with FreeBSD 6.x, and support
doesn't exist to get it fixed, mainly since, as most ppl here know, the
specs are closed, so even a non-Adaptec person can't do much to fix the
problem(s) ...
For those that haven't been following the discussion on this, the iir(4)
driver in FreeBSD 6.x appears to have a deadlock issue under medium to
heavy load, where the 'blocked' state just continues to rise until file
accesses just no longer work ...
So, if you are running a server that is using the iir(4) device driver and
are considering upgrading to FreeBSD 6.x and beyond, or are looking to
build a new machine using a device that relies on this driver, do so at
your own peril ...
Please note that this deadlock issue exists on *both* the ICP Vortex
cards, *and* the Intel based RAID controllers ...
If anyone from Adaptec is out there and is actually interested in seeing
this problem fixed, *please* let me know ... I have three servers, all
three exhibiting this problem, and one of them is fully loaded with the
kernel debug stuff so that I can (I think) give you almost *anything* you
want in the way of information concerning the problem ...
