Public bug reported:
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.
