So when I get this correctly load_builtin_intel_microcode() only works on !initrd ? Should this check not be the other way around ? something like : cd = find_cpio_data(p, (void *)start, size, &offset); if (!cd.data) { if (!load_builtin_intel_microcode(&cd)) return UCODE_ERROR; } Regards, Gabriel C
