I attempted to do an update from 28 to 29. Upgrade went fine but after logging in my system is almost unusable. very very slow. All cores are around 100%. Takes me about 30 min to get a top to load so I can see what it is. Looks like kworker has most of the cores and seems to be hung on a lscpu? When I saw that I attempted to run anything cpu query related and the commands just hang. I then wiped and reloaded fresh 29. Same thing again.

Lenovo 720s with a 8th Generation Intel® Core™ i7-8550U Processor.

I cant provide any logs because I ended up just reverting back to 28 since that and previous versions work just fine on this machine. Anyone else with this cpu having similar issues or is it just me?
