dmesg output flooded with "CPU Budget hotplug"/ "Mali: Set gpu frequency to X"
#1
Anyone know what would be causing this? dmesg is being flooded with these messages (just a snippet here):

Your CPUs get throttled because of the chip temperature going over the threshold (82C is the first trip point iirc). Depending on what you are trying to do or running on your Pine, you might have to think about a heatsink/fan...

Ah, thanks!

I am attempting to build swift-3.0 (using this as a reference: http://dev.iachieved.it/iachievedit/buil...erry-pi-3/), which pegs all 4 cores at 100% for a number of hours. Getting close to being successful, just having some issues linking against the python libraries...
