In there I found kernel-default-5.14.15, which I installed, and out comes: # dmesg | grep EDAC [ 0.757458] EDAC MC: Ver: 3.0.0 [ 6.854140] EDAC amd64: MCT channel count: 2 [ 6.854188] EDAC MC0: Giving out device to module amd64_edac controller F19h_M20h: DEV 0000:00:18.3 (INTERRUPT) [ 6.854189] EDAC amd64: F19h_M20h detected (node 0).
