I had the issue that, when attaching my Nvidia RTX 4090 to an appvm, the suspend also took long, with qubes.SuspendPre timeout messages in dom0 and when the system comes back, even though sys-usb found the devices, keyboard and mouse didn’t work. This fixed it. However, after the suspend the appvm has to be restarted, because the GPU does not work anymore: Unable to determine the device handle for GPU0000:00:06.0: Unknown Error Any idea how to fix that?
