But the last one calls out a SATA driver as the "probable cause".

I don't see anything wrong in the scanlog.
We don't really want duplicate threads here, but I will leave it open for the time being.
Try updating or reloading your SATA drivers.
Also do you have any external drives connected to this system through a USB hub ?
