Behavioral issues with ESXi 6.7 --
Discovered when trying to passthrough a cougar point SATA controller on my motherboard - it's a supermicro X9SCL-F, so it doesn't have ACS, but passthrough had been working since ESXi 5.5.
I toggle the SATA controller to passthrough, reboot. Upon reboot, passthrough disabled.
I thought maybe it was the fault of the VMKernel.boot.disableACScheck = false flag, so I set it to true. Reboot, flag set to false again.
I tried setting a VM to autostart. Reboot, VM not set to autostart anymore.
Does anybody know what's going on? Is this how it's supposed to behave? Google appears to be turning up nothing.
