@Mr Takashi Iwai, there's news, I have the Leap-15.4 Live system here, updated and got the same kernel as the native the Leap-15.4 system on my SSD (kernel is 5.14.21-150400-21.24.2). Rebooted several times, however could not find the 60���C idle temp issue with the Live system, ONLY on SSD as described above. Regards, M.
