Ah, so it's also the ASIX AX88179 that's causing you issues.

Mark and David, can you pull the 3.13-td-changes-reverted branch again,
and see if the latest patch fixes your issue?  It disables scatter
gather for the ax88179_178a device, but only when it's operating at USB
3.0 speeds.

Please test with it plugged into a USB 3.0 port, and when it's plugged
in behind a USB 2.0 hub.
