For boot up issue, the final weapon is Lautherbach T32,
these kind of hardware simulator can do hardware breakpoint after reboot,
And debug in single step with symbols loaded. 
but unfortunately most out of shelf uefi x86-64 board don't own JTAG interface. 
Then the traditional method is enable serial port and print more debug logs~
