In my mind that is a Vendor A problem not a generic OS or driver issue. Now after saying that if there is a class of issues that require a configuration I'm happy to look at providing that. > 150 systems is a not a large enough sample. > Agreed even if they are all different chip sets and controllers. On a side note: I am impressed with the serial ATA and the couple of products that I've seen so far. I think that this could remove the last barrier for ATA drives in larger systems and wait to see what products people come up with in the near future. > 500 ++ w/ various add-in cards * (the number of drive models per vendor) * > the number vendors eek stop .... > > Add in ATAPI devices, CFA, etc ... > > You see the combination are of a scale unchecked. > > I started at one point trying to have a single drive vendor with at least > 1000 or more systems in one lab to test their product over the host > hardware base, to run kernel checks.
