After the Monterey update all my regular workflows have been freezing constantly. Not even on heavy tasks.
I'd have sublime text, a few google chrome tabs, and a zoom meeting open at the same time.
The whole system starts stuttering/freezing. Sometimes my zoom call disconnects completely.
When I click on iStat menus in my menu bar it shows that kernel_task is using 500% CPU and that the clock speed is 1,00 GHz.
In my 3 years of using this MacBook for 8 hours a day on a daily basis I've never seen it run at 1,00 GHz and I've kept an eye on it a lot because of thermal throttling.
I've reset my SMC about 6 times in 1 day. The first 5 times the problem returned within 30 to 60 minutes after starting up.
The 6th time the SMC reset seemed to have fixed it. My MacBook worked fine for about a week and today the problem returned again.
Running 2 external monitors with each their own HDMI -> USB C adapter (1 plugged in on the left, other on the right side)
Main monitor is running 2560 x 1440 @60Hz
Second monitor is running 1920 x 1080 @60Hz
I use my MacBook with the lid open as a 3rd monitor.
