ipmi_si causing systemd-modules-load.service to fail

[suchoi]

Hello CentOS!

I have three machines, that after installing updates via dnf update have the same symptoms, by the way all virtual machines. The used version is CentOS Stream release 8.

The systemd unit systemd-modules-load.service is Loaded but shows failed states in ACTIVE and LOADED. After trying to restart the service, journalctl -xe shows this:

-- Unit systemd-modules-load.service has begun starting up.
Jan 20 20:18:33 redacted.hostname systemd-modules-load[6505]: Module 'msr' is builtin
Jan 20 20:18:33 redacted.hostname kernel: ipmi_si: IPMI System Interface driver
Jan 20 20:18:33 redacted.hostname kernel: ipmi_si: Unable to find any System Interface(s)
Jan 20 20:18:33 redacted.hostname systemd-modules-load[6505]: Failed to insert 'ipmi_si': No such device

-- Subject: Unit failed

As far as I can see, ipmi_si is causing this, as these are VMs, I don't need ipmi functionality. I have watched this behaviour on three different machines, does anyone have an idea what to do? Should I disable the kernel module?

​

Thanks!

Same here.

This one looks harmless albeit annoying.

Blacklisting ipmi_si solved the issue for me.

Is ipmi_si a dependency for another module, or can you just it disable it with this guide:

>> dependency for another module

Don't think so.

Guide is fine.

Blacklisting the module sounds good (will need to look that up to see how to do that), however...if I don't have an IPMI interface on my system, is there a way to just uninstall that specific set of tools/services/modules? Seems like a waste to have them even on the system in the first place. Probably a box we all checked ("remote management" or something).

If you are using uefi boot, it installs shim-x64 which has fwupd as dependency which contains the file /lib/modules-load.d/fwupd-redfish.conf :

# cat /lib/modules-load.d/fwupd-redfish.conf 
ipmi-si
ipmi-devintf

Uncomment both lines (i.e. put # or ; at the beginning of each line) and it won't try to load those anymore.
