Issue 512: Suspend/Resume may not work completely

Reported by Nikolaus Schaller, Nov 16, 2013

The 3.12.0 kernel needs to disable the OFF_MODE patches.

But Suspend/Resume may still not work completely.

And there are some messages, I/O errors and write errors for 
/sys/power/state reported.

Some errors observed:

Suspend seems to work reliably with these changes.

I see the mmc errors in my logs, but for me, all pwrdm's go to their 
target state.
