I have just built a kernel from the rt-sources-2.6.16-rt21 ebuild from the gentoo proaudio overlay. I used more or less the same config as I used for my previous 2.6.15-gentoo kernel (with custom reiser4 and suspend2 patches), except of course for the bits to do with preemption. With the previous kernel, cpu frequency scaling worked (despite a message I always got on boot telling me that it didn't). But with the new one it really doesn't work. Is this a know issue? I read one post from some other list suggesting that it was an issue for much earlier versions of the 2.6 kernel, but I couldn't really work out what was going on there. Also, there was a thread on this list a little while back which said that the realtime-lsm module is now deprecated. If this is so, what should I do instead to get realtime rights for non-root users?
