kvm guest is hung up when wx 4100 passthrough to win10 vm

1. It was enabled VT-d/AMD-Vi in BIOS

2. It also set /etc/default/grub as follow

GRUB_CMDLINE_LINUX_DEFAULT="radeon.blacklist=1 quiet splash intel_iommu=on pci-stub.ids=1002:679a,1002:aaa0"

3.And passthrough wx 4100 to win10 virtual machine, then win10 was hung up

4. Check vfio

[root@node-19 ~]# lsmod | grep vfio
vfio_pci 41312 1
vfio_iommu_type1 22300 1
vfio 32695 5 vfio_iommu_type1,vfio_pci
irqbypass 13503 10 kvm,vfio_pci

Is there any good advice?

Best regards

Installing wx 4100 driver (win10-64bit-radeon-pro-software-enterprise-19.q1.1-feb19.exe) at 50%, and then win10 vm was hung up, at the same time vm's cpu usage is 100% all the time.

Writing log to pid.txt with strace command, as follow:

......

the whole pid.txt is like this information.

Is it maybe a bug?

Could anybody give some advices?
