The CPU does not really matter much. I was talking about the disk connected to
your AHCI adapter. It links up at SATA-1 speed, which is uncommon for recent
drives. So I suspect your drive is old-ish, and old drives have the tendency to
be buggy and needing quirks...

What does "hdparm -I" say for this drive ?
