Intel Arc A750 hardware passthrough in Linux kvm

[kcw]

My Intel A750 in a Rocky 9 host is unable to boot VMs with the dGPU passthrough after recent OS update. Previously it can boot into guest once per host boot. Seems some kind of vendor power reset software is needed.
The dGPU connected monitor is frozen at boot menu (configured vfio driver with kernal cmdline), an attempt to boot VM will force reboot the host.

The reboot issue seems related to passthrough of a USB controller with a USB hub attached instead. Without the hub the VM can boot once per host boot now. Thanks
