In reading dmesg, I found this, scsi id7 is the controller:
scsi7: Someone reset channel A
scsi7 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
        <Adaptec aic7850 SCSI adapter>
        aic7850: Single Channel A, SCSI Id=7, 3/253 SCBs

(scsi7:A:6:0): Unexpected busfree while idle

could the system actually be turning off the Adaptec aic7850 SCSI adapter?

The Asuse K8N-E delux has 2 sata connectors IDE master 3 & 4 with
4 standard IDE, IDE0 master/slave & IDE2 master/slave. It also has
4 more sata conections for a sata raid, I have this disabled.
