Data points: * Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz * kernel 3.7.0-0.rc7.git0.1.fc19.x86_64 (I've seen this happen with stable 3.6.x kernels as well) It seems to happen at random boots, I'd say 1 out of 5 boots. The laptop fan keeps blowing, the temperature doesn't go under 65C, top says that the cpu is mostly idle and powertop says gpu is 100% "active" or "powered on".

Yeah I see this with 3.6 kernels. I started noticing it in the latest 2 or 3 kernel updates of Fedora 17. I currently have 3.6.8-2.fc17.x86_64.
Can you please watch i915_drpc_info to see if the values change while powertop reports 100% !idle.

I need more than one to see if the values are changing ;-)
(In reply to comment #7) > I need more than one to see if the values are changing ;-) Sorry, I totally misread what you wrote. I'll get back to you with that info soon.
(In reply to comment #7) > I need more than one to see if the values are changing ;-) Ok, it happened again on this boot, I'm now running kernel 3.7.0-1.fc19.x86_64. The values in i915_drpc_info don't change at all even between samples taken some minutes apart from each other. I can get more info while the laptop is in this state. I'll suffer the fan noise for a while.
No need, rc6 is then bust. Jesse please step forward with your patch...
Can you give this patch a try? https://patchwork.kernel.org/patch/1819391/
(In reply to comment #11) > Can you give this patch a try? > > https://patchwork.kernel.org/patch/1819391/ Sure, I built a scratch rpm with it if someone else running fedora wants to try: http://koji.fedoraproject.org/koji/taskinfo?taskID=4784182 I'm running with it now myself, let's give it a couple of weeks to be sure.
Ok, at the 6th boot with the patched kernel I got a bad one. GPU is 100% active again. Any other patches to try? :-)
FWIW, I just got into this state again when coming out of suspend with kernel 3.8.0-0.rc6.git3.3.fc19.x86_64 .
snb rc6 is unfortunately fickle ... *** This bug has been marked as a duplicate of bug 59368 ***
