Comment 28 for bug 1942616

I'm on Ubuntu 23.04 in Performance mode. When I run heavy tasks (machine learning) using my Nvidia GPU, CPU temperatures go around 90C, I get the "Performance mode temporarily disabled ..." and cpufreq-info displays:

  driver: intel_pstate
  CPUs which run at the same hardware frequency: 19
  CPUs which need to have their frequency coordinated by software: 19
  maximum transition latency: 4294.55 ms.
  hardware limits: 400 MHz - 3.60 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 400 MHz and 1.30 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency is 2.00 GHz.

So far so good, the problem is that, after cooling down and resting with no stress at all, it never resets to normal state. It keeps the temperature throttle indefinitely as if the computer was in full-charge. Only a reset fixes the problem, until I run another heavy task...
