UEFI 10G Intel X710/XL710 Hang Windows Splash Screen

[renato]

Hi, I did some more testing and i wanted to share my findings

I tested other 10G NIC cards all on a Dell server PowerEdge r630
Emulex OCm14104-U2-D 10DF 0720
Broadcom BCM95781 14E4 168E
Broadcom BCM95784 14E4 16A1

All of them presented the same issue so this take us away from a INTEL firmware issue
I also noticed that when the winPE image is PXE booted using the bootmgfw.efi directly taking ipxe/wimbbot away from the equation it boots fine. Then, I added ipxe.efi and then chain loaded bootmgfw.efi from there and it booted fine. Then, I started with ipxe but then switch to wimboot but instead of using http I used tftp and IT BOOTED FINE.

It is only the combination of ipxe/wimboot and transfer via http that fails to boot.

I used the tcp debug option and noticed that the connection is closed/shutdown randomly between 60 and 100% (it gets to tcp_wait_expired function) but continues downloading. Lastly it is weird that the md5sum of the downloaded files match the originals ie they are not getting corrupted.

I did ask Intel for support but they have not responded yet

hopefully you guys have a better insight now with my new findings
