I have the same issue, syslinux6.03, using syslinux.efi I have a HP G9 
BL460c blade with EFI and a vmware virtualised guest with EFI enabled.

I'm attempting to install rhel6.6, kernel 2.6.32. Both machines will 
boot successfully, load kernel vmlinuz, then start to load initrd.img 
but reset a minute or two later. rhel7 kernel 3.10.0 works better in the 
VM and actually loads successfully and kickstarts, but the HP G9 blade 
still resets whilst loading initrd.

The page at http://www.syslinux.org/wiki/index.php/Common_Problems 
Linux EFI pre-3.3
Most kernels before Linux-3.3 have also been observed to have other 
issues. Symptoms include spontaneous reboot at some point after kernel 
execution begins.

So does this mean we can't efi net boot rhel6/7 centos 6/7 or any distro 
that uses pre 3.3 kernels?

Thanks for any assistance.
