Warnings on update

anon14644943 · September 5, 2020, 9:59am

Since I additionally installed the 5.4 LTS kernel, I get some warnings with every update.

==> WARNING: Possibly missing firmware for module:

Here the last output from today:

Here is a thread about he same warnings:

anon14644943 · September 5, 2020, 10:21am

Ok, I wrote the blacklist, but how I can rebuild the initframe?

pebcak · September 5, 2020, 10:26am

You have to neither write the blacklist nor rebuild the initramfs. The conclusion in that thread was that this would not make any difference and those warnings are harmless. I still get them and my system works just fine.

anon14644943 · September 5, 2020, 10:35am

Many thanks @pebcak

joekamprad · September 6, 2020, 11:35pm

this one is new the 2 others are there for longer…

it is only a warning and only an issue on special hardware needing this firmwares to work.

anon14644943 · September 7, 2020, 12:01am

Obviously I then have this hardware. But I cannot do anything with this link, how should I be able to load this firmware? The problem with these warnings did not occur until I installed the 5.4 LTS kernel additionally. If I leave the 5.9 LTS kernel as fallback and the 5.4 is deleted, the problem should be solved, right? As I said, the messages did NOT come up when I only installed the mainline kernel.

joekamprad · September 7, 2020, 12:29pm

Possibly missing firmware it says the firmware seems not to be included in the kernels from Archlinux.

see here:
https://wiki.archlinux.org/index.php/Mkinitcpio#Possibly_missing_firmware_for_module_XXXX

first check if you have linux-firmware package installed:

core/linux-firmware 20200817.7a30af1-1 (121.6 MiB 562.5 MiB) (Installed)
    Firmware files for Linux

then provide hardware info:

Off Topic Doubt

What happens if I uninstall this ??

joekamprad · September 7, 2020, 1:39pm

i do not see such device at your system, if you could provide journal from last boot i can validate 100%
simple search journal for firmware:
journalctl -b -0 | grep firmware

joekamprad · September 7, 2020, 1:40pm

you will miss all firmware files it includes, and devices needing such will not work properly, if you have any that needs such …

So I have to uninstall it to find out if I really need it , right ?

Well , I like experiments

anon14644943 · September 7, 2020, 1:45pm

with yay -Rns -linux-firmware or only yay -R linux-firmware?

joekamprad · September 7, 2020, 2:54pm

no firmware loading error, so all good.

joekamprad · September 7, 2020, 2:55pm

i would say in most cases you will see no difference… but let’s test it oi do also:

not that interesting…

mandog · September 7, 2020, 3:13pm

Their is a simple answer to this
If it was not on the fallback img it would be a problem
Its not on the fallback img that means you do not have the modules so the firmware is not installed.
Fallback image tries to load all modules whether installed or not as its a fallback img so nothing to worry yourself with, its all in the arch wiki somewhere

dalto · September 7, 2020, 3:20pm

Unless you are in a VM, I would be somewhat hesitant to remove the linux-firmware package. It contains a lot of firmware beyond what would be needed by your initramfs.

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/

If you do remove it, make sure you have a cached copy of the package first as you may lose your network.
