toastman Posted May 16, 2019 Share Posted May 16, 2019 (edited) Asus B450-f Gaming Ryzen 2600 GT720 (for unRaid) GTX950 (for passthrough) In trying to diagnose a number of errors (namely a 127 error affect one my my PCIe slots), as well as get Primary-GPU passthrough working, I noticed there was a BIOS update for my motherboard that included the new microcode for the 3-series ryzens, etc. So I updated. After that, no VMs needing GPUs would boot (127 / D3 error). Not only did a restart of the server not clear the problem, it never actually restarted. Watching the shutdown process I noticed it went through everything appropriately but the shutdown signal never actually turned the server off; I had to do the push-and-hold of the power button to actually get it to power off. After a bunch of messing around that didn't fix the problem I went back to the previous BIOS (2008) and all the problems disappeared. Luckily Asus' ez-flash allowed 'updating' to an older version. I suppose there's something between the BIOS and unRaid that isn't playing nice thats causing these problems. I don't know enough about much of it to offer any other conclusions than that.
