Resetting CPU ...

If you copy in a loader.efi from an earlier build (e.g. r313109) then the 
system boots but complains about SMP problems, fails to start any of the other 
CPUs (although it sees them) and panics before it reaches a login prompt with 
what appears to be a problem reading the SD card (I also get a couple of lor's 
in here too..... not sure if those are "real" or false positives)

Booting [/boot/kernel/kernel]...

There's not a lot changed between 313109 and 313441 in the loader.efi
and arm64 pieces of sys...... any ideas what boogered it?  (Also have
posted on this in -arm, but since it's Pi3 specific and that machine is
-HEAD dependent is this the better place for it?)
