ESXi version: 5.5u3
Motherboard: SuperMicro X10SRH-CF BIOS v 3.2 (latest)
OS VMs - WIndows 2012R2, with all mandatory updates installed
I'm using this ancient version of ESXi because it's the last one that SuperMicro asserts supports this motherboard.
Windows 2012R2 can successfully access various PCI passthrough controllers in PCI slots, but when I enable the onboard SAS 3008 controller, it won't boot.
But a Debian 10 vm starts fine and can talk to the 3008 without issue. So this is clearly related to Windows.
I'm a ESXi n00b. How do I go about debugging this? Which logs should I examine?
