PSOD with Intel X520 PCI Passthrough to Server 2012 R2

[FernandoSuperGG]

ESXi is PSOD'ing when running the "Intel Hardware Diagnostics" tool.

Steps to reproduce:

Device Manager > right click on X520 > Link Speed > Diagnostics > Hardware > Run Test

Hardware:

- Dell R710, Intel Xeon L5520, 64GB Memory.

- Intel X520-DA2

Software:

- R710 BIOS 6.4.0

- 6.5.0 Update 1 (Build 5969303) [Dell Custom ISO]

- X520 Adapter Driver 22.9.16.0 (on guest)

I can't get the logs anymore, only a screenshot attached, but I'll report this anyway...

A couple things, I see. First, may not be related, but just FYI all Dell 11th gen servers like your R710 are not officially supported with vSphere 6.5. Second, since this is a 10 GbE card, I noticed your build number is one impacted by a long-standing bug having to do with 10 GbE adapters. VMware just released a patch for this on Tuesday that will bring the build number up to the 7 range. It's highly recommend you install that build.
