$ cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 2.20 GHz
available frequency steps: 2.20 GHz, 2.20 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
boost state support:
Supported: yes
Active: yes
Note that current policy: frequency should be within 800 MHz and 800 MHz.

If it was a kernel bug as I thought at the start, it should appear to me again...
Other than that turbo mode seem to triggered it for me too before bios update

install i7z to monitor these cpu's if you already dont.
something strange you could try is install enlightenment17. it defaultly has a cpufreq module/gadget, even when i dont have cpufreq installed, i can still use the gadget to throw it on manual and lock it anywhere between 800mhz-3.1ghz.
-didnt know was solved already
]]>Today I found a "hacked" bios for my laptop that the only thing it does is unlocking an "advanced" menu and without making ANY further changes the problem stopped by miracle today after years!
I will wait 2-3 days to test it to be sure and i will mark this thread as solved.
Also this is the link of the bios just in case anyone else searches for it: link
thanks for your interest
]]>more progress:
i installed gnome3(i had kde) and did the same thing all normal no lags no stuck at 800mhz...edit: its irrelevant, happened in gnome too
Did you try disabling webgl in chromium? Didn't you say that's what you thought was causing the issue?
