the NIC is the same realtek 10ec:8168

I am trying to pxe boot winpe and I have successfully booted other systems with Broadcom and Intel NICs, however for this Realtek NIC I haven't had any luck.

has anybody fixed this issue?
ribalda patch did not work for me, I keep getting the same error
if I switch to ipxe.efi everything is downloaded successfully (Im using wimboot) but while wimpe is starting the systems freezes in the windows logo with no error messages.

Any Idea what may be causing the snponly error or the hanging?

Thank you

Renato
