Hardware Error Microcode a20102b Ryzen 9 5950X

Ah! Thank you! It is still an active Kernel Bug! (Atleast in LTS) Thank you for the resource! I will test and come back here for future documentation.

Also seems to be pretty similar to this: Full system freeze on new install after some time - #19 by aFriendlyTurtle

In the wiki post you linked, it has a post from another forum linked. They talked about how a motherboard vendor recommended increasing RAM voltage by .050V, which is also mentioned in this manjaro forum post, they also increase CPU core voltage by .050V. I’ll see which solution is best. GRUB param, voltage bump, or your suggested PBO fix.
