Hi Mario, I tested reverting commit 4dbd11796f3a on my HP Zbook Firefly G10 with a Ry= zen 7 PRO 7840HS, as you suggested. Result: The problem was resolved. I performed the test cycle more than 10 t= imes and the CPU frequency scaled normally after every single resume.=20 Before the revert, the problem would consistently occur during the test cyc= le described below: 1) Laptop in use plugged on HP charger (any power profile) 2) Close lid of laptop 3) Unplug HP charger 4) Wait a few seconds 5) Plug in HP charger 6) Open Laptop - See that the CPU is stuck at 544 Hz. 7) Unplug and plug the charger makes the frequency normal again at a minimu= m of 1101 Hz but scaling normally. My system details: - Model: HP Zbook Firefly 14 inch G10 A (SBKPF,SBKPFV2) - CPU: AMD Ryzen 7 PRO 7840HS - BIOS: V82 Ver. 01.09.00 - OS: Fedora Silverblue 42 Thank you for your help.
