/me wonders whether an issue at my system is connected to this bug repo=
rt too.

I'm using the ondemand governor at a ThinkPad T420 with a i5 (4 cores, =
2.6 GHz
max frequency, boost at 3.1 GHz). Since kernel 3.10-rcX I've to define
"intel_pstate=3Ddisable" at the kernel command line to force using the =
acpi
driver (P-State does not know anything about niced processes ...)

Now the problem:
After s2ram and wakeup I notice a higher temperatur and fan noise and r=
ealized,
that 3 of 4 cpu cores runs constantly at 2.6 GHz (cpu1-3, cpu0 were at =
the
expected 800 MHz for low load) - independend from the load. I've to exp=
licitely
set the max freq to 2.4 GHz and back to 2.6 GHz. Then the current frequ=
ency was
scaled accordingly to the load.
