The problem appears to be resolved by disabling the “OS Management of the Embedded Security Device” in the BIOS. When I do that the system boots up successfully. Not sure if booting up in Windows-10 will reset that in the BIOS though; I seem to recall it does which is a real PITA when trying to switch between booting Windows and NetBSD on this system.
