Sleep transition timed out after 180 seconds while notifying clients about upcoming system capability changes.

My MacBook Pro keeps crashing when trying to go into sleep mode. I also keep getting the same error message:

Sleep transition timed out after 180 seconds while notifying clients about upcoming system capability changes. Suspected bundle: com.apple.iokit.IOGraphicsFamily. Thread 0x74.

Any help would be greatly appreciated.
