We ran into this issue twice so far, once beginning of the year with a couple of Gigabyte boards and some weeks ago with a couple of Intel 4th Generation NUCs. The NUCs were simple to solve as Intel has provided a BIOS Patch. With the Gigabytes, after one week we had analyzed it so far that simply attaching a HDD used under OpenBSD (not only a system disk that was installed upon) would trigger this problem. Rewriting the partition table with fdisk on another machine let the 'faulty' boards access their bios again and see the disks. Our suspicion at the time was the block size used by the OpenBSD system (512 vs 4k) We also disable UEFI boot in the bios. Cheers, Kim
