Subject: [REGRESSION 3.10.1] System does not wake up from suspend

Hi Greg,

since upgrading to 3.10.1 I find my system not waking up from suspend
from time to time. Unfortunately, I couldn't figure out how to reliably
reproduce the issue. Sometimes it works just fine.

All I know so far:
On 3.10 I had my system completely freezing a few times. But that did
not seem to be related to suspend/resume. I never experienced the
behavior described below on 3.10.

On 3.10.1 I hit this bug a few times, that my system did not wake up.
I.e. the screen stayed black and the power LED kept flashing. But
nothing brought the system back up and I had to longpress power to reset
the system.
I had none of the system freezes like the ones described above anymore.

My laptop is a Lenovo T510 running Arch Linux. I also attach my kernel
config, just in case.

	Thanks,
	Sören
