Hi, I'm trying to kexec Debian netinstall and normal kernels on my ARM64 devices but the kexec'ed Debian kernels are failing to retrieve the EFI system stables. I have tried buster and bullseye. This causes the installer and distro to lose EFI support.
If I run the ISO or linux/initrd combination manually from u-boot shell via bootefi, it works properly. This issue also does not happen with Fedora or OpenSUSE or my own normally compile kernels. Was wondering if anyone else experienced this issue?
