dmesg-3.10.4

Hi,
  I reported in the past all kinds of PCI/ACPI-related issues with this Dell Vostro 3550 laptop, in respect to USB also problems with XHCI ports falling asleep in conjunction with e.g. laptop-mode-tools setting upstream PCIe root port into sleep state. The XHCI contorller is from Texas Instruments. More in linux-usb archives and kernel bugzilla.

  With this new kernel, I see for the first time the following messages (did not appear in 3.9 or earlier as far as I remember). Both XHCI ports were unused since I powered up the laptop (no external device were ever connected to them since cold boot).

Sadly I don't have enabled XHCI_DEBUG so cannot provide more information from the logs. Maybe you could log more?
