Last Saturday night, I upgraded from Ubuntu 20.04 to 21.10. In reviewing my logs, I've noticed that immediately upon my upgrade, and lasting since, my PC's CPU temp baseline has jumped 15-20°. See charts from Friday, Saturday, and Sunday below, for comparison. I'd love to know if anyone has any thoughts on what might be going on.
Device specs: AMD Ryzen 5 3600, 64 GB RAM. I'm happy to provide any other info that might be helpful. I pull CPU temp with a script that runs every 5 minutes and reads the Tctl value from sensors.
UPDATE WITH MORE INFORMATION:
I've confirmed that pwrstatd was what was causing the high temps, and I feel like a complete dope for not checking sooner. Every day since I upgraded to 21.10, pwrstatd has been, as of my morning logs, either 93.8% or 100% CPU usage. I killed it yesterday afternoon, and here's what my temp graph looked like from this morning:
After I killed the daemon, I tried running "pwrstatd --help" just to get some more info on it, but that generated a segmentation fault. After I rebooted, the daemon no longer seems to be running. If anyone knows what my next steps should be, I'm open to suggestions.
