Termination and termination power is OK in both buses. I strongly believe that it could be the firmware. It is an old and unmaintaned board with a build in SCSI bus so no chance for a firmware upgrade, checked that one already. I will probably switch it to another SCSI bus and see if that helps but in case of a firmware bug, that I strongly believe this is the case here, is there a workaround? I recall that Adaptec had a firmware bug in all controllers with earlier versions than 3.00.
