Subject: RC6 for an Intel GU doesn't always work
Date: Wed, 10 Oct 2012 18:33:49 +0200 [thread overview]
Message-ID: <5075A36D.2000301@gmx.de> (raw)
Sometimes - after a reboot or after wakeup from s2disk I'm observed at
my ThinkPad T420 (i5-2540M CPU) w/ integrated intel graphic (i915
module) since 3.6-rc(5?), that the temperature is above 80°C (usually it
is around/lower than 50 °C). Powertop-2.1 shows, that the all 4 CPU
cores are mostly idle, but the GPU is running at 100%. It looks for me
that the power saving mode RC6 isn't active.
After 1-2 s2ram's however the issue went away.
I'm observing the issue both under my Gentoo Linux and under a RH system
(kernel 3.6.1 each).
It is hard to bisect b/c not reliable.
