Re: snapshot boot fails with error "entry point at 0x1001000"

Hi all,

For the record, Mark Kettenis' patch below fixed the boot stuck problem
on my Intel NUC Kit NUC7PJYH mini server, see the following email thread:
https://marc.info/?l=openbsd-misc&m=160391516603159

Thanks a lot for this.

Cheers.
Fabian
