[syslinux] Booting with Syslinux 6.01 & 6.02 fails, causes restart.

Where did you get the Syslinux source? Could you try with the latest 
from Arch Linux [testing], just in case?

FWIW, the Syslinux archives in kernel.org already contain binary 
files. Using official files without re-compiling might help find out 
if perhaps there is some build problem.

Are you using gnu-efi 3.0u? If not, please update.

Were you using the same exact procedure, in the same order and exact 
commands with Syslinux 4.xx?

Any specific reason to use "-s" in the installer? Could you try 
without it?

Could you try installing gptmbr.bin first, and then executing the 
extlinux installer?

Are you using c32 modules?

Have you changed anything in your /boot/syslinux.cfg file? Can you 
post it?

Have you tested Syslinux 4.07?

Which filesystem is /boot ?
