Hello,

 

I thought I would move my transcoding to my RX 550 which has been sat idle for almost 6 months, In the past I had no issues with GPU passthrough but right now my Windows 10 doesn't boot and locks all cores to 100%, no display on my TV either.

 

I just rebooted with Hyper-V set to 'YES' and managed to RDP in for around 10 seconds and then it froze as soon as I turned the TV on and now it's back to 100% CPU cores and no response, any ideas?

 

Config:

CPU Mode - Host Passthrough

Initial RAM: 8GB

Max Memory: 8GB

Machine: i440fx-4.2

BIOS: OVMF

Hyper-V: Yes

Graphics Card: AMD Radeon 540/540x/550/550X / RX 540x/550

Sound Card: AMD Baffin HDMI/DP Audio

Network Bridge: br0

PCIe ACS override: Both
