when enabling runtime PM of the usb3 controller, I start getting the same warning message[0] and the usb3 port become unusable (sometime i get an other error message too[2]) then when disabling the runtime PM of the controller and plugout/plugin the usb device, I don't get the warning message anymore This happens on both my ubuntu & my archlinux (kernel-3.14.4) for the same reason NOTE: I'm also getting some other errors from time to time [2] [3] My EFI/BIOS firmware is up-to-date but seems still buggy and I'm having some acpi compatibility issues, even I'm having bug on usb_wan module only on ubuntu caused mostly by the firmware [4]
