The DVD/RW drive is the only drive on ata6. The harddisk on ata5 is recognized without problems. After the above 3 attempts to scan ata6.01 the boot process continued normally and all drives are working fine (HD and DVD). It seem that libata thinks there is a drive on ata6.01 but there is none (->Ghosting?). I figured there were such issues earlier with other chipset. Is there something to do about it?
