Yeah, some of messages are no longer emitted for memory-less nodes (NUMA 1 and 3). Your patch set also overhauls the messages. But, the amount of redundant messages I'm complaining about has actually increased: dmesg|grep EDAC|cut -c 16-|sort|uniq -c 256 EDAC MC: UMC0 chip selects: 256 EDAC MC: UMC1 chip selects: 1 EDAC MC: Ver: 3.0.0 128 EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load. ^ three lines each 64 EDAC amd64: F17h detected (node 0). 64 EDAC amd64: F17h detected (node 1). 64 EDAC amd64: F17h detected (node 2). 64 EDAC amd64: F17h detected (node 3). 512 EDAC amd64: MC: 0: 0MB 1: 0MB 256 EDAC amd64: MC: 2: 0MB 3: 0MB 256 EDAC amd64: MC: 2: 8192MB 3: 0MB 64 EDAC amd64: Node 0: DRAM ECC disabled. 64 EDAC amd64: Node 2: DRAM ECC disabled. 256 EDAC amd64: using x4 syndromes. (Full dmesg at http://ix.io/1T1o) While on 5.3-rc5 without the patchset I get: 1 EDAC MC: Ver: 3.0.0 256 EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load. ^ three lines each 64 EDAC amd64: Node 0: DRAM ECC disabled. 64 EDAC amd64: Node 1: DRAM ECC disabled. 64 EDAC amd64: Node 2: DRAM ECC disabled. 64 EDAC amd64: Node 3: DRAM ECC disabled. So I wonder if we could deduplicate those. Meow! -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ A dumb species has no way to open a tuna can. ⢿⡄⠘⠷⠚⠋⠀ A smart species invents a can opener. ⠈⠳⣄⠀⠀⠀⠀ A master species delegates.
