Title:
  xhci_hcd 0000:00:14.0: WARN Event TRB for slot 1 ep 2 with no TDs
  queued?

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have an Acer Aspire M5 481T and when I ask Ubuntu 15.04 to shutdown
  it seems ok and goes off with 100% of battery, when I turn it on again
  it has only 5% or worse, 0% of battery, so it is not shutting down
  correctly. What could be happening? Could be related to the warning
  above?

  I' m receiving a lot of these messages in dmesg:
