+Why does kworker hog your CPU (cont.)? As an alternative to my other answer here, Perf is a more professional way to analyse what kernel tasks are hogging your CPU:
+
+Install perf:

+sudo apt-get install linux-tools-common linux-tools-3.11.0-15-generic
+(The second package must match your kernel version. You can first install just linux-tools-common and call perf to let it tell you which package it needs.)

+Record some 10 seconds of backtraces on all your CPUs:

+sudo perf record -g -a sleep 10
+Analyse your recording:
