Hi all, I've been trying to build a Hackintosh VM in the last months. After a lot of research and suggestions from the community, I've decided to buy a new "ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller" to play nice and natively with my Mac setup. Following the guides of @SpaceInvaderOne (thank you so much man), I have set up the VM and properly passed though the PCI card. Things are going well and everything works fine until I ask the Mac VM to restart or shutdown. If any of the 2 options are executed (either though the VM itself or from VM section on Unraid) the VM shuts down then the system (server) hangs. I have to manually force reset the whole system (server) cause everything is unresponsive and cannot access WEB GUI or ssh etc. I started investigating on the issue and checked the logs. Seems that the problem has to do with the ASM1142 PCI card. In the system log right after I execute a restart or shutdown I get the following: Posting my IOMMU groups: As you can see the "AER: Uncorrected (Fatal) error" on "[8086:2f04] 00:02.0" device that is mentioned in the system log is the PCI bus that the "ASM1142" PCI card is installed. In order to completely be sure that its the card that has the issue I tried the following: Used the ASM1142 PCI card in a Windows 10 VM and got the same error and behaviour (without it everything works fine) Enabled (previously disabled) "PCIe ACS override" and tried all combinations Enabled (previously disabled) "VFIO allow unsafe interrupts" and tried all combinations. Passed through the "IOMMU group 13: [8086:2f04] 00:02.0 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02)" that system log mentioned that has the "AER: Uncorrected (Fatal) error" Nothing of the above solved the problem. I have to mention that sometimes the system doesn't hang completely, but the VM page cannot load up (other VMs work fine), dockers run fine. When that happens the RAM that was allocated for the VM that failed stays allocated, even after I manually turn off the VM Manager from settings. When I turn on the VM Manager again, the VM Manager is still unresponsive and cannot have access to it. Then if I try to restart the system or shutdown, it hangs and I have to reset again. Any help would be greatly appreciated. BR tower-diagnostics-20200211-1059.zip
