No solution, but it is quite similar in daedalus using the liquorix kernel. It worked up to 6.3, 6.4 shows an error as above.

The following worked for me to migrate bookworm to daedalus in a virtual machine.
ssh'ed in the vm, then copy-pasted commands.

No guaranty!

$ cat migration.notes.txt

Just curious: Does the sound work in devuan when using /etc/modprobe.d/alsa-base.conf from ubuntu?

Sound is not a general problem. Notebooks can be special in different degrees.

A bit of googling:
Ubuntu seems to produce custom images for the Latitude 3420. https://ubuntu.com/certified/202101-28600
There was a question about missing sound here: https://askubuntu.com/questions/1291829 … -ubuntu-20
Not exactly the same model, maybe the answer applies to your case too.

Don't know either, there should be no problem with 5.10. Alsa devices are looking good too.

I did a bit of testing, but have no speaker connected to any HDMI output ... .
I temporary installed pulsaudio, and could switch to a HDMI output device. The config was present.
qasmixer shows no level-fader for the HDMI audio output.

The generic name for the current kernel is "linux-image-amd64"

$ sudo apt install linux-image-amd64

should install daedalus' kernel 6.1.

You mentioned the kernel version: 5.10 is chimaera, daedalus has 6.1 and I would use this. Maye the old kernel is still booted as default for some reason?

The following command shows all sound devices on my box:

 $ cat  /proc/asound/pcm
00-00: ALC1150 Analog : ALC1150 Analog : playback 1 : capture 1
00-01: ALC1150 Digital : ALC1150 Digital : playback 1
00-02: ALC1150 Alt Analog : ALC1150 Alt Analog : capture 1
01-03: HDMI 0 : HDMI 0 : playback 1
01-07: HDMI 1 : HDMI 1 : playback 1

That's all I got ...

Just recognised:

root@devuan:~# ssh devuan  

is (herer) equal to

root@devuan:~# ssh root@devuan

To login with a non-roor-user:

root@devuan:~# ssh your-non-root-user@devuan

Does this work?

Good morning. Not sure about the question, there is systemctl in devuan. I usually do

$ sudo apt install task-ssh-server

to have ssh server installed and running.

EDIT:
Ooops, I messed this up entirely:  "... there is no systemctl in my devuan" is correct.

I would fix /etc/fstab first:
  a) the error in line 1
  b) temporary comment-out all non-linux filesystems

And try a live system (knoppix, or whatever you prefer) to confirm the hardware is ok.
Are there other OS'es, and if so do they show errors too?

Is it a new or an old installation?
If it is new one, I probably would just re-install. Or maybe trying to update to daedalus.

Of course not.
But this is what you get, when using the linked installation instructions on chimaera.

Let's say there was a temptation to suggest "wouldn't you like to do a dist-upgrade to daedalus?", instead of answering the question.

Some thoughts:
Correct BIOS time and non-fucntional RTC sounds contrary. Both are the same device, aren't they?

Debian shows correct time: Probably systemd-timesync forces a clock-update. ntpd could do so too with addional switches. google found e.g. https://askubuntu.com/questions/254826/ … -using-ntp

cat /proc/interrupts|grep -i rtc on my 97x-based mainboard looks almost equal, only one of the four zeros is not zero. Just to mention, whatever it means.

Thanks for the info - I was not aware of that possibilty.

At least there is nothing strange happening, as thought before.
