I installed Debian Bookworm on my Lifebook U9310 CometLake today. Everything went very well. However, what I find quite peculiar is that the CPU clock speed is set to 2100 MHz. When I put a load on the CPU, the clock speed drops to 1600 MHz. The correct configuration would be for it to be at 800 MHz when idle and 1600 MHz under full load. It's very strange; I've never experienced something like this before. The configuration is as follows: Intel_pstate=active, HWP=active, Turbo_boost=off, powersave_mode. To avoid any misunderstandings... the CPU is not under load at 2100 MHz and remains fairly cool in terms of temperature."
