tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Title:
  USB3 boot device lost during system boot: "xhci_hcd 0000:04:00.0:
  Error while assigning device slot ID"

Status in linux package in Ubuntu:
  New

Bug description:
  Booting Ubuntu 15.04 amd64 kernel "Linux version 3.19.0-16-generic
  (buildd@komainu) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13) )
  #16-Ubuntu SMP Thu Apr 30 16:09:58 UTC 2015" on a Samsung RF711-S08
  laptop (Sandy Bridge) from a USB3 stick connected to the USB3 port on
  the righthand side, the boot stalls at the Ubuntu splash screen (with
  the dots), with the USB3 stick LED showing no activity, eventually
  dropping to the initramfs console. If I unplug and replug the USB3
  stick during the stall period, the LED shows activity and the boot
  proceeds.

  The same USB3 stick boots on another laptop without any problems.

  Excerpts from dmesg:

  Recognition of the USB3 port:

  [    1.643737] xhci_hcd 0000:04:00.0: xHCI Host Controller

  Failure to initialize the USB3 device:

  I assume the bug is at 1.847589.
