Bug detailed description:
--------------------------------------------
System failed to resume from S3 with warm boot on latest -next-queued kernel.
When I reboot the machine with command "reboot", then do S3, system can not
resume from S3, but reboot the machine.  
But if I cut off power, then boot the machine, do S3, system can resume from S3
successfully.
We got this machine not long ago, this is the first time we tested it. And I
also tested older kernel but I can't find a good commit, so I don't think it's
a regression. 

lspci:
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:0a26]
(rev 09)


Reproduce steps:
--------------------------------------------
1. warm boot
2. echo mem > /sys/power/state
3. press "power button" 
4. system can not resume but reboot
