Framework 12 (12th Gen i5) freezes after a few minutes on CachyOS in performance mode

I’m running into a stability problem on my Framework 12 (5 configuration) when using CachyOS. Whenever I switch to “Performance Mode,” the laptop freezes completely after about 5 minutes. The display stays on, but the system becomes fully unresponsive and requires a hard shutdown.

some additional info:

  • Happens both on AC and battery

  • Tried limiting C-states with intel_idle.max_cstate=1

  • Did a completely fresh reinstall of CachyOS on a different SSD

  • I do not have this problem on other distributions (e.g., Zorin OS runs fine)

  • Temperatures on CPU and SSD seems fine (below 80°C even when playing light games)

i was wondering if anyone else has this problem.
