Can not boot RHEL 7.3 by using iPXE

RE: Can not boot RHEL 7.3 by using iPXE
For people finding this post because they have issues installing RHEL 7.3 / CentOS 7.3 on UEFI hardware using iPXE...

There is a bug in the "stock" kernel that came out with 7.3 and the installer pxelinux/vmlinuz image is not working.

The updated kernel, i.e. kernel-3.10.0-514.2.2.el7.x86_64.rpm fixes this issue.

Hopefully, this will save someone from wasting time like I did. If someone has a "simpler" alternative to the solution I posted earlier in this thread, or if the nice people supporting CentOS decide that it would make more sense to update the installer vmlinuz / initrd and squashfs, I think that the iPXE community would thank you!!!

* After migration to Red Hat Enterprise Linux 7.3, the Unified Extensible
Firmware Interface (UEFI) boot failed due to a bug that prevented the kernel
from booting through the PE/COFF image entry, which is used by the Extensible
Firmware Interface (EFI) ipxe boot loader. This update fixes the alignment
parameter on the call to the efi_low_alloc() function, and the kernel now boots
as expected. (BZ#1392044)
