Even with just a few percent cpu use, it spins the cpu up to it's full boost on one or more cores, and tends to keep it there for an extended period. Ever since my laptop has been significantly warmer, and louder than it was a while back. Cpu is a: i7-3720QM Current kernel is: 3.14.4 (debian) I've also tried vanilla kernels: 3.13, 3.14-rc8 Disabling the intel_pstep driver seems to disable boost states completely, which is odd, as I could swear it worked before without it. Is there something I can do to keep boost states while reducing the heat and noise? It seems to be way over compensating for minimal amounts of cpu use. -- Thomas Fjellstrom thomas@...llstrom.ca -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
