We have received new 6008-SV modules that failed. The problem was identified as a firmware bug. The problem appears to be with the prom located nearest to the VME connector. I can not be sure which prom versions are bad. However I suspect any V2.x version. We replaced the V2.x prom with a copy we made of a V1.x prom and it worked just fine. The symptoms I saw were queue overflow messages and dbior showed many command errors and a maximum of about 10 block transfers per second. This was on a system that does >40 block transfers per second. Marty Kraimer
