We downgraded those messages recently to KERN_DEBUG. If you boot with "debug" on the kernel command line, you'll see them. > [ 6.854189] EDAC amd64: F19h_M20h detected (node 0). And I think I know which one is still missing: b4210eab9164 ("EDAC/amd64: Set proper family type for Family 19h Models 20h-2Fh") which adds support for those 0x20 models. Would you like to try a test kernel like the last time? Thx.
