The current efi code emits the error message like Couldn't get size: 0x800000000000000e on various Dell and other machines. Although the whole problem is the buggy firmware, showing this as an error level is rather annoying, as the error message appears over the boot splash. Basically this is the result of missing entry and we have no explicit way to fix it for such a firmware problem, the error message may be suppressed. This patch changes the error print condition and suppresses the error message if status is EFI_NOT_FOUND. It's a partial patch from the more comprehensive one Joey Lee submitted in the past.
