Title:
  drm complains bitterly when discrete graphics turned off

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I'm using radeon.dpm=0 and radeon.runpm=0 for reasons explained in a
  previous bug report.

  I'm able to turn the radeon discrete graphics off using

  echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
  echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

  and my power consumption drops dramatically to a nice low level,
  but then the kernel log starts filling up with all sorts of complaints from drm:

  etc., at a great rate!

  The whole point of the exercise is to keep the discrete graphics off,
  so why is drm:radeon_cs_ioctl still trying to issue commands to it?

  Also, Ubuntu doesn't want to shut down cleanly after the radeon
  discrete graphics unit is turned off.
