Hi Sven, misc, Thanks for your email and the effort of putting up a patched EFI boot file. Much appreciated. It took a long time to make a release in my case.
I too can confirm that the patch by Marc Kettenis linked below [1] resolved the boot issue on the Intel NUC. It boots fine again now, and I could complete the post-upgrade steps for OpenBSD 6.8 release without problems. To resolve the issue, I basically did what you suggested. However, after the heads-up from Theo in the other email thread [2], I used the BOOTIA32.EFI and BOOTX64.EFI files from the latest official snapshot, and not the one that you shared earlier. Specifically, I did the following: * Boot into bsd.rd * Mount the local GPT EFI partition (mount -t msdos /dev/sd0i /mnt/efi) * Download the BOOTIA32.EFI and BOOTX64.EFI files from the latest OpenBSD snapshot from one of the mirror servers * Copy the two files into the EFI partition, replacing the files that were installed during the upgrade to OpenBSD 6.8 release * Reboot That procedure worked fine for me and was reasonably straightforward. Cheers.
