[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Could well be the GPU OC, the script commands are as follow:

To disable the OC just change 800 to 600 or 666. Available frequencies are 100, 177, 266, 350, 420, 480, 533, 600, 666, 733, 800.

echo 800 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq_gpu;

EDIT: Here's a script with all the new control interfaces (DYNAMIC Hotplug, etc.), as well as some values that this kernel changes from stock.

To use the script, download the attachment, remove the '.txt' bit and execute. If it doesn't run you might have the change the file permissions to executable.
