Beacuse we see the following:

Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
(Note that use of the override may cause unknown side effects.)
The first one tells the Node is disabled
The first one says *DRAM ECC* is disabled on that node - not the node
itself. Looks like it confuses you too.
Yes ofc :) is what I meant :)
the second is a
KERN INFO message telling the *module* will not load.
Telling then *module* will not load for 'this Node' should be clear for everone.
So this is a purely informational message. There's a lot of messages
like that in the kernel. I still don't understand what your problem is
with this particular one.
Nothing agains messages but I get this one twice for each node is disabled
with a INFO I partially don't even need on that platform.
Don't get me wrong for me is clear what this means , I don't need the
second message at all but I have here folks didn't understand wth that means.
"ECC disabled in the BIOS or no ECC capability, module will not load." -
I think that sentence is explaining the situation pretty good:
either ECC checking is disabled in the BIOS
or
ECC capability cannot be detected.
What do you think it should say instead?
The message is fine if you add a Node prefix on it and let the
that ecc_enable_override stuff out.
something like this looks better and less confusing , don't you think ?
EDAC amd64: Node 4: DRAM ECC disabled.
EDAC amd64: Node 4: DDRM ECC disabled in the BIOS or no ECC capability, module will not load.
EDAC amd64: Node 5: DRAM ECC enabled.
EDAC amd64: F17h detected (node 5).
