SCCM vNext OS Deployment problem

Hi Everyone,

I'm testing the new SCCM (vNext) but I've a strange problem when deploying OS via PXE.

If I deploy it to a Virtualmachine it works perfectly.
If I deploy it to a workstation it works fine too.
But if I try to deploy it to my HP EliteBook 820 I get an error:

SmsTftp.exe - Application Error

The exception Illegal Instruction
An attempt was made to execute an illegal instruction.
(0xc000001d) occurred in the application at location
0x00007FFEFC1C5C01. 

I though it was a network issue, but with F8 i can ping every server, FQDN, and websites.

I've also tried to inject the driver of the ethernet (Intel I218-LM) but nothing changed.
The client doesn't get the Task sequence (because I've tried also to deploy it as: Available)
