Hi Rafael, I got a copy of the below bugreport in my mailbox and I was wondering if this rings any bells. Are there any relevant power-management / scheduler changes in 5.7 (vs 5.6) which might be related? And is there any quick way for the reporter to test this (by e.g. picking a different scheduler / cpufreq-governor).

With latest kernel-5.7, cpu temperatures are noticeably higher. Using kernel-5.6 my idle cpu temperature is around 35-40°C, but with kernel-5.7 its around 50-55. Htop and KDE System Monitor don't show anything using cpu and idle cpu usage on both kernels is 0-2%. I first noticed this issue on kernel-5.7.6-201.fc32.x86_64, and it is also there with kernel-5.7.7-200.fc32.x86_64. Booting with kernel-5.6.19-300.fc32.x86_64 fixes the issue. Are you running any modules that not shipped with directly Fedora's kernel? No. -- You are receiving this mail because: You are on the CC list for the bug.
