How do I stop looking for ipmi/BMC?

waynew · 2018-04-02 13:17:09

On boot, a few seconds after my login prompt (text, not graphical) shows up, a message pops up, "there appears to be no BMC at this location".

Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory

From what I can tell, that looks like I don't have any IPMI, or at least it doesn't work (properly?). My computer is a Lenovo ThinkCentre M78.

Is there a way that I can tell my system to stop looking for BMC and/or ipmi? I did a `systemctl status | grep ipmi` and didn't get anything, and I don't see anything that seems pertinent with a `locate ipmi` either.

Any ideas? Thanks!

Neither of those would find anything, ipmi are kernel modules: `lsmod | grep ipmi`.

You could likely blacklist these modules, but I have absolutely no background to suggest this - blacklisting these may not be wise.

Well, that's more helpful:

❯ lsmod | grep ipmi                                                                                                                                                                                                                                                            (0)08:16
ipmi_si                65536  0
ipmi_devintf           20480  0
ipmi_msghandler        53248  2 ipmi_devintf,ipmi_si

So it looks at least like they are loaded. Hm, I wonder if that's why I'm also getting a `failed to start kernel modules` at boot.

If it doesn't keep spamming dmesg then I'd say just ignore it, if you blacklist it now then later if it is needed for something else you might get breakage that might be hard to debug.

If it keeps spamming dmesg then complain upstream as most probably that is some unhandled case that upstream might want to know about.

Does the system have a baseboard management controller?

If you have and use IPMI (via a BMC) you know it.
There should be no harm blacklisting it.
