E/ANDR-PERF-MPCTL: Invalid profile no. 0, total profiles 0 only

Question

Although my App is working fine but I am receiving these errors in the logcat. Can anyone tell me what are these errors?

I don't have an answer, but I do have too much to fit in a comment!

Based on this comment, it seems to be to do with power management profiles:

Can you check the logcat and see if you get this message:

E/ANDR-PERF-MPCTL(907): poll() has timed out for /sys/module/msm_performance/events/cpu_hotplug 
E/ANDR-PERF-MPCTL(907): Block on poll()

If you do, it may explain the idle drain you have. Seems like this is an issue with this specific profile because I've tried all the performance and balanced profiles

Any chance you're using a custom power profile in your kernel, or can edit your question to include your phone / OS type?
