--- Comment #37 from Joshua M. Thompson ---
I'd just like to chime in, since I've been having similar runpm problems with
both 3.13 and 3.14 kernels on my laptop with built-in Intel HD4000 and a Radeon
7730M. The dGPU is constantly suspending and resuming every few minutes, even
though nothing is using it (although xrandr offload has been configured). This
is accompanied by the burst of kernel messages mentioned above, as well as
several seconds where the mouse cursor moves but X is otherwise unresponsive.
If I let the laptop sit idle for a while and come back it'll be frozen with a
blank screen, presumably because it either froze up blanking the screen or
shortly after.
Running with radeon.runpm=0 eliminates the freezes and the lockups, but it
keeps the laptop running a lot hotter than I'd like.
