DIMMs, ECC and mci handler

Support Kernel
1

I’m seeing these in dmesg:

[  +0.000022] EDAC sbridge: CPU SrcID #0, Ha #0, Channel #0 has DIMMs, but ECC is disabled
[  +0.000071] EDAC sbridge: Couldn't find mci handler
[  +0.000063] EDAC sbridge: Failed to register device with error -19.

I remember getting these on other distro’s as well, but never took the effort to ask about it.
Anyone any idea how to fix/prevent these?

Hello @TriMoon :wink:

I think it is for ECC RAM as here mentioned:

https://www.kernel.org/doc/html/v4.14/driver-api/edac.html

Since i have no ECC RAM i blacklisted it:

blacklist edac_mce_amd

Idk which module you use…

Do you use ECC RAM?

3

Not according to my BIOS info, and there is no option to flip/test it…

I see not edac module… strange… but anyway:

errno says about error 19:

$ errno 19
ENODEV 19 No such device

So in general this can be ignored.

Yea i know, but it bothers me to see those lines repeated multiple times.
I just want to know how to prevent them…

What about these modules ecc / ecdh_generic?

7

I don’t think so, that this helps, because bluetooth uses this module… :smiley:

However… I have found this one:

 $ locate sbridge
/usr/lib/modules/5.4.79-1-MANJARO/build/include/config/edac/sbridge.h

But it is a empty file. I would try to blacklist sbridge in /etc/modprobe.d/ .

echo "blacklist sbridge" >> /etc/modprobe.d/blacklist.conf

Maybe this helps.

I somehow don’t think that is a very safe thing todo to disable the module for the Mainboard’s SouthBridge…
Besides an empty header file doesn’t say the module has no source code…
(But it could as well be a bug by the packagers)

As a side note, i also seem to have this:
Missing device driver

9

You are right… bad idea :stuck_out_tongue:

That was not my intention to say that. :wink:

Ive found this:

and i guess the module is then sb_edac. Maybe blacklist this one?

10

What effect will that do, if the module is not dynamically loaded, eg. listed in lsmod…

This is the device that is unclassified in the picture i posted above:
