Re: [IMPORTANT] Adaptec no longer supporting iir(4) driver ...
A quick follow up on this email ... please note that I have not, in this email, pointed to anything but the iir(4) driver, and, more specifically, the GDT controller card ... I have been using Adaptec products since the early 90's, and, until upgrading to FreeBSD 6.x, *never* had a complaint with them ... this email was meant to be a 'caveat emptor' for anyone looking to use the iir(4) driver, and is not meant to apply to *all* Adaptec cards, as they don't all use the iir(4) driver ... Apologies to all who took this as a broad attack against Adaptec, it was not meant as such ...

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 ...
