Do you mean efi64/efi/syslinux.efi?  Any chance you can try the
precompiled binaries from 6.03-pre7 from kernel.org?

What exact make and model of your CPU and system/motherboard?  What
BIOS/firmware version?  There's a significant chance you only have
EFI32 services so EFI64 syslinux.efi isn't an option.

especially the archives of mailing lists.
Q: Why is Top-posting such a bad thing?
