Hey Maarten, sorry I took so long to respond to this.

OK, so you don't get any output on the serial console. Were you passing
"console=" on the kernel cmdline? If so, the best way to debug this hang
is to add,

efi_call_phys4(sys_table->runtime->reset_system, EFI_RESET_COLD,

just after we setup 'sys_table' in efi_main(). If your machine resets,
then we at least know that the firmware loaded the bzImage correctly.

P.S which machine is this and what is the output of the 'ver' command?
