You can't PrintStr() anymore after ExitBootServices().

And you also can't just arbitrarily remove code and expect things to
still work.

Looks like it is (otherwise you would see some sort of error message).

If you're having real problems, the may be connected to the EFI
implementation on your system and/or the EFI version being too
old (no minimum version was established so far, but it may well be
that some things aren't working as expected in older versions).

I take it that native Linux boots okay on that system?
