On a related note: I think this patch/issue may be the cause of the -rt CPU frequency scaling bug I reported a couple of months ago. http://comments.gmane.org/gmane.linux.rt.user/12472
I'm currently using the performance governor by default as a workaround; thanks to JackWinter for packaging in the ArchAudio repos.
Cheers, -Harry
