'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 ...
