So far we haven't hand any issues w/ 6.0 w/ the iir drivers from 6.1 yet.. but we also haven't deployed our product into production... On 5.4-R we got a few months in before we had the hangs and had to ditch 5.4-R... > Doug> Any advice is welcome.

I wouldn't be surprised if the other motherboard could exhibit the hang too.. since I believe it's a firmware race condition, and the other motherboard may have different timing characteristics that makes the hang less likely... /me has zero trust in iir cards until Adaptec/ICP-Vortex admits there is a problem and fixes it. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
