I've recently acquired a Gigabyte Z170X Gaming 7-EK motherboard with the Intel Z170 chipset and Sunrise Point-H USB 3.0 xHCI Controller for running Linux. Now most things seem to work fine (some problems with UEFI but that was kind of expected), but the xhci_hcd module is filling up my log files with a repeated message (ever 4 seconds): [ 2137.036187] usb usb2-port1: Cannot enable. Maybe the USB cable is bad? [ 2137.036981] xhci_hcd 0000:00:14.0: Cannot set link state. [ 2137.037767] usb usb2-port1: cannot disable (err = -32) Now I have no idea where usb2-port1 is or why it should have a bad cable, the only USB devices I know of are the USB drive I've booted the system from and the wireless keyboard/mouse combo I'm using. Both seem to work just fine and plugging those into different USB ports doesn't change the message.

The current kernel is 4.14.13 (from Mageia 6). Any idea what the problem here is and how I can fix or work around it? Please let me know if you need any additional information on the system or environment.
