Description J. Neto 2016-06-06 17:23:44 UTC

Reclocking isn't working in linux 4.4 and 4.5, 4.3 is ok. I didn't test linux 4.6. 

Right after echo 03 > pstate the screen glitches, but I'm able to safe reboot by sysrq method.

There are no errors on the log.

I've followed this guide: https://wiki.ubuntu.com/X/MMIOTracing

And during the tracing I've run: xinit -e sh -c "glxgears & sleep 10"
