My guess is that the loader.efi is hung by exactly the same reason - = there is some bad (unexpected) value, also the printed out (null) hints = about weirdness there, because we normally get (null) when NULL pointer = was passed to printf(). So either we should debug the loader.efi or = efibootmgr to identify why it is hung and fix the code to avoid it.=20 rgds, toomas >=20 > /H >=20 > On 23 October 2018 at 22:51, Kyle Evans <kevans@freebsd.org = <mailto:kevans@freebsd.org>> wrote: > Hi, >=20 > I suspect 4th vs. lua has no impact here, given the output shown -- > can you throw one of the installer images [0] on some removable media > and give that a shot for booting?
