Hello, The patch "CPUfreq ondemand: handle QoS request on DVFS response latency" that introduced the mentioned errors requires the patch "PM / QoS: Introduce new classes: DMA-Throughput and DVFS-Latency" get merged, too. I guess that patch will be at pm-qos tree if get merged (v2 patch has been released 7 days ago). Cheers!
