[Powertop] Has anyone seen power bugs from kill -STOP process before and after S3 sleep?

I'm still trying to figure out why my laptop can idle at 12-13W or 20W
with no differences in processes, and why powertop (even latest, 1.25)
can provide very incorrect power values.

One thing I do that likely few people do:
killall -STOP chrome chromium firefox-bin xmms mplayer pidgin procmeter3 plugin-container

That seems to work with power of course, but I think it later causes
problem when I go to sleep (shut the lid) and come back later.

Have others seen issues with this?
It's happened for me for over a year, all the way to kernel 3.11

Could it also be generating the weird powertop behaviour I get and no
one else does?

Thanks,
Marc
