Public bug reported:
I have desktop pc, AMD platform, also AMD graphics card. It was running
Ubuntu 20.04. Because I switched the graphics card I plugged my system
on a power meter. After the switch, the installation consumed ~100W.
Some weeks later I installed Ubuntu 24.04. The bad experience is a
different story. I managed to get it running. Now the System consumes
190W. No hardware changes!
CPU load shows ~0, LAMP shows ~7W for the graphics card. All disks spin
down after 15 minutes. Nothing could explain 90W. Even the CPU is
limited in the BIOS to 65W.
Is it possible that the new Ubuntu overwrites the power limit of the
CPU?
