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...

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.
