--- Comment #12 from Michel Dänzer (michel@daenzer.net) --- (In reply to Janpieter Sollie from comment #11)
disabling CIK support in my kernel and upgrading it to rc6 solved the problem. Probably CIK and SI are not really cooperating properly yet.
Weird, does rc6 still work with CIK support enabled?
