Logfile containing errors

The system (Dell 7440, Intel  i7-4600U) failed to power down during suspend. This may be related to i915 cannot set power state correctly as shown in log attached.

This is probably related to:
http://patchwork.freedesktop.org/patch/43731/

If this is related, is it possible to add the affected (i.e. 4th gen intel) Dell system, too?

Cheers
Martin
