(It still boots via BIOS.) If I revert that commit on current master (c309bfa9b481), it boots correctly again [although I see "setup_efi_pci() failed" being printed]= =2E (Seems like it freezes when handle_cmdline_files() attempts to read the last chunk of the initramfs -- the last call to efi_file_read() never returns. Figuring out why that happens is beyond me, though.) --=20 Mantas Mikul=C4=97nas
