(Get the code!)
Perhaps you get Code 43 because mobile NVIDIA chips make use of Optimus which requires significant proprietary firmware support. QEMU/VFIO has never claimed to work with such devices. The further speculation in the original report that QEMU corrupted something in Linux seems unjustified, the device simply doesn't work a second time. This might be lack of proper reset support in the GPU itself or poor interaction with aforementioned proprietary firmware.
