case? Does anyone know if the AIC7xxx driver causes problems with SCSI

Bear in mind that SCSI controllers *can* freeze entirely when they
encounter errors. This depends greatly on the brand and model as some
are far more fault tolerant than others, having little to do with the

Aah--I should have suspected as much. The drives claimed to be

Make sure your drives are jumpered to spin up automatically instead of
waiting for a wakeup signal from the SCSI controller. Enable a spin up
delay if necessary to spread out the PSU load. See if this helps...
