Hello,

I've got a weird disklabel related problem (or so it seems). When I
partition my harddisk with fdisk and add an OpenBSD (A6) primary
partition the system can still boot, but once I place a disklabel
on the partition (disklabel -E sd0) I can't boot the system anymore
(it freezes during the post).

System Info:
- OS: OpenBSD-current AMD64
- CPU: Intel Core i3 4130T
- Motherboard: Gigabyte GA-B85M-DS3H
- Harddisk: WD Green 1TB (SATA)

It is possible that it's a Gigabyte specific problem since Karl
Karlsson has the same problem with his Gigabyte GA-Z87MX-DH3
motherboard.

The other strange thing is that if I use an USB-stick instead
of the harddisk I can install and boot OpenBSD without problems.
Even with the harddisk present, but without a disklabel, I can
still boot from the USB stick, but as soon as I place a disklabel
on the harddisk (although it isn't used, nor in the boot sequence)
the system freezes during the post again.

Any suggestions on how to fix this or should I just buy a different
motherboard?

Kind regards,


Martijn Rijkeboer
