just a guess, but do you have some variants that are UEFI and others that are not?

Hello, I'm at a loss as to what's causing this issue on my setup.

I have a CentOS 7.3 server with cobbler and xinetd.  I have a pxe menu entry for the vanilla centos LiveCD that looks like this:

/images/centos_livecd/centos_vmlinuz initrd=/images/centos_livecd/centos_livecd_initrd.img ksdevice=bootif lang= root=live:/centos_livecd.iso kssendmac text ks=http://10.101.24.21/cblr/svc/op/ks/profile/centos_livecd BOOTIF=<MAC>

The non-working behavior is:
 - Hit enter
 - Kernel downloads
 - Initrd downloads, but silently (only 3 "."s show up, but I can tell its downloading watching tcpdump)
 - The download finishes, the screen flashes, and the PXE menu comes back up
 - Subsequent retries result in the menu flashing and coming back up with an "invalid kernel parameter" error

Again - I have about 15 units of varying motherboard and platform NOT working, and about 40 or so units of varying motherboard and platform that ARE working with the exact same menu entry and no configuration differences.

Can anyone help me?
