Indeed. Experiments here show that plugging in a pci - sata card to avoid the Intel SATA chip makes the disk work fine. Disks smaller than 1TB also work. So I'm guessing it's something magical about 4K-sector disks presenting themselves as 512-byte sector disks that is the source of

So marking a partition as 'Active/Bootable', (the 00 - 80 change) causes your system to hang. Apparently Linux does this when you 'Label' it. The OpenBSD installer does it for you when you select 'Whole disk'. Nothing obviously to do with the disklabel. You could test this by manually
