I'm having similar issues with Windows 10 and GPU Passthrough w. Unraid 6.9
- VFIO bind RTX2080 via System Devices + reboot
- Start Windows results in black screen
- (Zorin also results in a black screen)
Mar 4 14:07:17 ThreadRipper kernel: vfio-pci 0000:42:00.0: BAR 1: can't reserve [mem 0x80000000-0x8fffffff 64bit pref]
2021-03-04T22:07:12.979196Z qemu-system-x86_64: vfio_region_write(0000:42:00.0:region1+0x101260, 0x0,8) failed: Device or resource busy
Any help is much appreciated!
