Have you tried using powerprofilesctl to change the power profile to 'performance' instead of 'balanced' or 'power saver'? I think this would prevent the lowest idle states at least. Just a guesss, never had this problem myself.

My modern CPU problems are DDR5 and the pre-boot timing thing never completing. So a build of a 9700x that I did that WAS supposed to be located remotely from me has to sit in my office and have its hand held thru every reboot cuz you never know quite know when its doing to decide it needs to retime and randomly never come back. Requires pulling the plug from the back and waiting a few minutes then powering back, then waiting 30 minutes for 64gb of ddr5 to do its timing thing.
