I have a brand new Lenovo T14s AMD laptop with the Ryzen 7 PRO 4750U CPU.
Whenever I boot the machine, I see the error listed below. 

I have verified that this occurs with the latest kernel
(5.3.18-lp152.60-default), the previous kernel (5.3.18-lp152.57-default), as
well as with the kernel that is included with the openSUSE 15.2 Live USB Stick. 

I have also verified that it occurs with various "mitigation" command-line
arguments (off, on, auto).

I have also verified that it occurs when booting a different Lenovo T14 AMD
Laptop which suggests it's not a bad component in my particular machine.
