As a further test, I've tried booting the following Trixie USB stick in BIOS mode via the rescue menu: Debian GNU/Linux trixie-DI-alpha1 "Trixie" - Official Alpha amd64 NETINST with firmware 20241230-11:26 This succesfully gets me to the rescue process and allows me to chroot into the host after typing the long commandline series above. Basically, a/b testing shows that Trixie kernels per-se work fine, but something fishy is going on with the grub-efi-amd64 in Trixie. The same host was originally installed with a Bookworm mini.iso on USB and booted fine via EFI, so the problem really does seem to be the grub-efi-amd64 in Trixie. Martin-Éric
