It doesn't follow the drive. It sort of stays with port in that sense
that it happens on the first equipped port after the first one (which is
probed by the controllers BIOS). If I leave the second port empty, it
happens on the third when I do a cold boot.
I have also moved the drives around, and it does not follow the drive.
One odd thing that I've noticed is that it's only happening on my
Samsung drives, I've got a couple of WD aswell and they seem to work.

No, same behaviour.

I had to change it to:
ata_port_printk(ap, KERN_WARNING, "XXX error_intr irq_stat=0x%x\n", irq_stat);
I hope that was correct.
Yank the drive:

The drive seems to come alive and seems to start at [ 119.350834] above.
But then it's been tried 3 times and is already disabled.
