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: Jun 19 10:19:43 HP-ubuntu kernel: [ 360.548772] radeon: switched off Jun 19 10:19:44 HP-ubuntu kernel: [ 361.083818] radeon 0000:02:00.0: couldn't schedule ib Jun 19 10:19:44 HP-ubuntu kernel: [ 361.083872] [drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to schedule IB !

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.
