port-i386/54191: i386 kernel does not boot via 64-bit EFI
>Synopsis: i386 kernel hangs/reboots when running via 64-bit EFI bootloader
>Arrival-Date: Fri May 10 15:15:00 +0000 2019
>Originator: Michal Gorny
>Release: NetBSD 8.99.37
System: NetBSD pomiocikbsd.local 8.99.37 NetBSD 8.99.37 (GENERIC) #0: Thu May 9 14:42:33 UTC 2019 email@example.com:/usr/obj/sys/arch/i386/compile/GENERIC i386
I have installed NetBSD/amd64 on UEFI using information from . I have
added the EFI bootloader to my systemd-boot instance, and the amd64
version is working just fine.
Afterwards, I wanted to install i386 version of the system. However,
the kernel fails to boot when started via 64-bit EFI bootloader
(from /usr/mdec/bootx64.efi). If CSM is disabled, it reboots immediately
after loading the kernel. If CSM is enabled, it just hangs with blank
screen (and non-blinking cursor at top).
For completeness, I should add that 32-bit EFI bootloader (bootia32.efi)
can not be used on 64-bit UEFI (EFI says that the binary is invalid).
Install NetBSD according to the linked guide (I had to enable CSM
and boot BIOS-compatible bootloader from install image). Then start
64-bit EFI bootloader and try to boot the kernel.
I have also tried building and installing the kernel from trunk.
