I have problem booting 32bit kernel on UEFI (Both on VirtualBox and Real System). I got kernel panic when initializing efivars. I guess efivars on 32bit kernel try to use 32bit EFI data structure when booting on 64bit UEFI. This may related to problems I found before about efibootmgr because different efivars sysfs data structure is different when running 32bit and 64bit kernel. If efibootmgr compiled for 32bit it cannot be use on 64bit kernel (and also 64bit UEFI) and vice versa. https://bugs.gentoo.org/show_bug.cgi?id=431984 So anyway It means I cannot update UEFI boot variables either booting 64bit kernel with 32bit userland or 32bit kernel. Only way is to boot 64bit kernel + userland to do that.
