hibernate fails while uvcvideo fails to unload

[guivho]

Binary package hint: hibernate

Frequently, hibernate fails due to uvcvideo. I do not know what the package is for uvcvideo. Hibernation sometimes works, but most of the time it fails due to uvcvideo not unloading.

Following instructions in
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume

* Had to comment GRUB_HIDDEN_TIMEOUT=0 in /etc/default/grub followed
  by 'sudo update-grub' in order to see the grub menu when booting

* Booted with no_console_suspend option

* Successfully issued 'sudo pm-suspend' on VT1

* When resuming, it shows a black screen. Ctrl-Alt-F7 shows the
  X-desktop, Ctrl-Alt-F1 the VT1 screen which launched the suspend. No
  messages.

* Issued 'sudo pm-hibernate' on VT1. Everything seems to work as
  expected, but the power stays on. VT1 displays following 3 lines:
  btusb_intr_complete: hci0 urb ffff880037ad8480 failed to resubmit (1)
  btusb_bulk_complete: hci0 urb ffff880037ad8900 failed to resubmit (1)
  btusb_bulk_complete: hci0 urb ffff880037ad8600 failed to resubmit (1)

* Have to hit the reset button to get going -> normal boot. System
  starts with networking disabled. 'Enable Networking' solves
  this. But that should not be needed.
