PCIe Bus Error - RHEL compatibility issue with Skylake?

I'm having trouble trying to install Redhat from USB.
I have two USB sticks, one with RHEL 6.8 and the other RHEL 7.4, which
have worked on different hardware.

This system has Intel Core i7 6820EQ (Skylake) with 16Gb DDR4 RAM.
Whether I use the v6.8 or v7.4 installer, both get into an infinite loop with this error:

PCIe bus error corrected
AER error Device Id=00ea Device=[8086:a11a]

Trying various boot flags generates a device controller error:

It appears there is a compatibility issue with Skylake.
Any advice most appreciated.
