Title:
   XHCI (USB 3.0) kernel Module Prevents Hibernate

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On a system with an ASROCK N68S motherboard and a VIA VL800/801 PCI
  USB3 adapter, the system, which is a 64 bit kubuntu precise with a 3.2
  kernel cannot hibernate.

  When you ask the system to hibernate, the OS does everything it should
  and also appears to shut down the system (the fans stop). However,
  after half a second the system restarts by itself, resuming from the
  hibernation.

  If you unbind the xhci_hcd driver from the usb card on the pci bus,
  before hibernation then the system hibernates and resumes in the
  correct way.

  So, the very same hack proposed in bug report 522998 at comment 61
  seem to (hackishly) fixes the issue.

  IMHO this looks like a bug in the xhci driver. Please report upstream.
