Strange thing appearing during boot

This only appears to happen during boot, it doesn't seem to get recorded in the syslog after boot.  I am not even sure if this is really a problem, or not.  But it doesn't look like the kind of thing that is best ignored without even looking into it.  Please, shed some light on it.
I value your time, I know you have things to do, and I am grateful for any assistance I may get.

Re: Strange thing appearing during boot

Hi

until you get a better reply.....are you using that Atheros device for your internet?

if so you may like to run with root powers

modinfo ath10k_pci

you will see some firmware files may be required.

but the list of PCI IDS in that command are misleading. Instead
https://pci-ids.ucw.cz/v2.2/pci.ids might be easier to search for your device.

also as a non-root user....but do not post full output please....just your network device if you have any concerns

lspci -vvv

should show you the details of your device.

2) I assume you are using AMD graphics? if so post

inxi -Gxxx

Re: Strange thing appearing during boot

The atheros device is a wireless LAN device that I installed a driver for but am not using for internet presently.

Here's the output for modinfo ath10k_pci:

I'll check the virtualization.

Yes, it is enabled in the BIOS.

It is maybe worthy of note that the iommu lines often don't appear with these other lines, when these other lines show up.  Also, since it seems that none of these lines showed up during this boot, it seems like perhaps all of them don't always show up.  The non-iommu lines are common, though.

Re: Strange thing appearing during boot

Try the iommu=soft kernel command line parameter.

And for outdated PCI IDs use

# update-pciids

Re: Strange thing appearing during boot

We know you have the 9377 WLAN device, so if you do wish to pursue that it will need a firmware file and
I can not find it in Devuan at the moment.

I did find
https://packages.debian.org/buster/firmware-atheros
which contains those fw files

Re: Strange thing appearing during boot

firmware-atheros is "in" the devuan repository:

$ apt-cache policy firmware-atheros
firmware-atheros:
  Installed: (none)
  Candidate: 20190114-2
  Version table:
     20190114-2 500
        500 http://deb.devuan.org/merged beowulf/non-free amd64 Packages

Like most of the packages in devuan, it gets pulled from debian and merged with our repo of forked packages. We don't actually host the un-forked packages on devuan servers.

You need to enable the non-free repository to get it with apt.

Yeah well I did not even an entry for it. Just made one now in /etc/apt/sources.list

deb http://deb.devuan.org/merged beowulf non-free

Maybe....add that line with it commented out for members to easily spot....
In the next test release?

either in above file or a file under /etc/apt/sources.list.d/

cheers

Re: Strange thing appearing during boot

I already have firmware-atheros.  Thank you for the attempts at helping.  My WLAN device appears to work.

I used update-pciids now and upon looking it up, it appears that iommu=soft can be placed in /etc/default/grub.  Is that correct?

If it is, I'll give it a try. I guess editing:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=soft"
might work?  I am not very knowledgeable in how to handle this.

Apologies for my late reply.

Yes, that will work. Run update-grub to generate a new boot menu after you edit the file.
