Oh damnit, damnit. I've been having those on 10.15.4 too, was really hoping they'd fixed it on this one. It's really profoundly upsetting to spend $3,500 on a brand new computer by the most reliable major manufacturer in the industry and still have daily damn kernel panics.
I have had too many bad experiences with Lenovo business class desktops and servers to hope that one product line from them is somehow exempt from reliability issues.
Also a product long past it’s glory days. Ditched my less than year old X1 Carbon to get a 16” MacBook Pro because it was randomly dying while purporting to have 25% battery left.
