E / ANDR-PERF-MPCTL: Invalid profile number. 0, total profiles 0

Question

Although my application works fine, but I get these errors in logcat. Can someone tell me what these errors are?

I have no answer, but I have too much to fit in the comments!

Based on this comment , this seems to be related to power management profiles:

Can you check 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, this may explain your useless stock. It seems like this is a problem with this particular profile because I tried all the performance and balanced profiles
