DELL ESXI host crashes - How to figure out faulty hardware

Question

I have a ESXI host that has crashed several times due to hardware issues. Every time in the logs I see:

A bus fatal error was detected on a component at bus 64 device 2 function 0.
A bus fatal error was detected on a component at slot 4.

On the console I see

64 in Binary is 40 in hex. If I do:

[root@localhost:~] lspci | grep 0000:40:02.0
0000:40:02.0 Bridge: Intel Corporation Xeon E7 v2/Xeon E5 v2/Core i7 PCI 
Express Root Port 2a [PCIe RP[0000:40:02.0]]
[root@localhost:~]

When doing:

esxcfg-info

and looking for SLOT 4 I get:

Does this mean that the CPU is going?

Have you tried to run any [diagnostics](https://www.dell.com/support/article/us/en/19/sln283546/how-to-run-hardware-diagnostics-on-your-poweredge-server?lang=en) on your server? — Appleoddity, Nov 26 '17 at 20:43
Did you fully update the VMware software or the BIOS late last week? If it has an Intel processor they released microcode for it and then pulled it back because it is causing problems like this. If you downloaded an update before the pulled it that could explain it. — Todd Wilcox, Jan 24 '18 at 18:00

The iDrac doesnt show any issue about HWs? Maybe you should run full diagnostic at the boot screen.

If I remember correctly:

Press F10 at startup. In the left pane of Lifecycle Controller, click Hardware Diagnostics. In the right pane, click Run Hardware Diagnostics. The diagnostics utility is launched.
