From what I remember of reading some mailing lists thoroughly, some drivers can gain from doing a 'cpu nodatacache' and 'cpu datacache' pair just about the driver activation.
Another thought: you can type 'version' in shell? It should say Kickstart 40.68. That is I think the driver is trying to use scsi.device and if it can't recognize it, has to fail/abort. Why it wouldn't recognize, is harder to tell.
