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.

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.
