Hi Arne,

Thank you for your reply.

Yeah, I am aware of the error page and checked the list from the
additional notes. That's the reason I wrote that the Linux kernel is
compiled with the CONFIG_EFI_STUB option.

I am also definitely sure that the kernel image isn't corrupted in some
way as it works seamlessly with other hardware in UEFI mode. The same
applies for the iPXE binary itself which works on other hardware, too.

The notebook has definitely no BIOS legacy mode, it just boots in UEFI
mode. The iPXE EFI binary itself is loaded correctly by the firmware via
HTTP with the URL supplied by DHCP. Chainloading further iPXE scripts
works correctly, but iPXE is unable to load subsequent EFI binaries.

Regards, Felix
