[linux-audio-user] A question of kernels

I have been reading about the -ck patchset (http://ck.kolivas.org/faqs/audio_hints, http://members.optusnet.com.au/ckolivas/kernel/) and was wondering if it is or is not good for audio? The reason I am asking is that Ubuntu's kernel is patched and a lot of users rely on those patches, and although I have received a -rt patch that applies to the Ubuntu kernel, it does give me many issues (interestingly, only with RT apps like JACK and the like). The Ubuntu kernel can be patched with -ck rather easily, and most people that have tried it seem to say they have been results than using the standard Ubuntu kernel (me excluded). I saw that it uses CFQ as the default scheduler, but that can be changed back to anticipatory easily enough. I understand that Ingo's -rt patches are best, but is the -ck patchset better than a vanilla kernel, for audio, as a medium? Why or why not? Also, why does Studio To Go! use it if it is bad? Thanks for any insight in advance. Dana
