amd passthrough to vm, start with error message: error writing '1' to '/sys/bus/pci/devices/0000:06:00.0/reset': Inappropriate ioctl for device

[wustrong]

start vm success, but prompt that:

error writing '1' to '/sys/bus/pci/devices/0000:06:00.0/reset': Inappropriate ioctl for device
failed to reset PCI device '0000:06:00.0', but trying to continue as not all devices need a reset

randomly, the vm and host both crashes, other vm still work well.
