I've been noticing the issue of not being able to change frequency governer on -rt kernels here. I've posted to the -rt mailing list, details here (click "next in thread" to follow convo): http://marc.info/?l=linux-rt-users&m=140897493204106&w=2 In short, there seems to be something going wrong with locking / unlocking an RW lock that is used during a CPU freq scaling. I have pin-pointed the issue to a pretty specific place in <kernel>/drivers/cpufreq/cpufreq.c but I don't know how to fix it. Note that I'm running 3.14.12-rt9-1-rt (Arch linux, from AUR) but the issue seems identical to me.. I have an older CPU (Core2Duo from about 7 years ago), but I read in the forum link you have an i7? That shouldn't have the same issue... I'll post to the -RT list, mentioning your email, and you system config, and see if the devs there think they're releated or different.
