Today I've tested v4.8-rc7 (without the patches above). The USB 3.0
ports have stopped working completely for me. Neither USB 2.0 nor USB
3.0 are being detected. The Ethernet port does not work, too. The USB-
2.0-only Port works.

There also a new problem: my XU4 does not reboot or poweroff anymore.
When I force-remove the dwc3 module reboot / poweroff works again.

There are some failures in the dmesg log, see below.

Best regards,
Michael
