Also no sata errors anymore. However it is not reliably waking up (at least when all of the above except CLASSIC_RCU is on). Sometimes the display remains black on the console, but X still works and sometimes it hangs completely on resume. Also when compiling these many kernels via make -j4 I noted that I could hardly move the mouse / use the keyboard, but saw random jumps and key-repetitions...
