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. -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
