[IMPORTANT] Adaptec no longer supporting iir(4) driver ...
'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 ... ---- Marc G.

[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 ...

Specificly v1.14 and v1.13.2.1 of iir.c that limits the simq to 32 commands? We are running w/ this modifications w/o issues on 6.0-R w/ SRCU31A and SRCU42L cards... We have a few GDT cards also that I don't believe we are having any issues with... Infact, scottl tracked down that change after a bit of proding from me on behalf of my employer nCircle... (Though it helped that he was able to reproduce it in his lab.)... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
