Suggestion from IRC was to add "iommu=soft" to kernel command line. This resulted in grub or the kernel booting right back to BIOS again. No kernel messages were visible.

Same thing happens with ata_ignore_hpa=0.

(It's a normal 3.5 inch disk, not a laptop one, in case the hpa thing refers to the hidden partitions on windows laptops.)
