Hi

 

Anyone come across this error in the log before?

 

I am passing through my samsung nvme 950 pro drive to a windows 10 VM. It starts up fine on the first boot.

However, when I restart windows or power off/on the VM i get the following error in UNRAID and unable to boot from the nvme drive again until i restart the unraid host. I tried a different slot for the nvme drive and also the vfio_iommu_type1.allow_unsafe_interrupts=1 in sysinux but it doesnt make a difference. The nvme drive is in its own IOMMU group.
