Thank you for the report, and apologies for the angst.
The following note is for the CC's, not you, Zamir.

@Morgan, @Dave
I have no experience of Netinstall, and wonder whether it can operate in text mode. If it can, and get far enough to install inxi, we can ask for the O/P from 'inxi -MSGxx'; and possibly the system journal? Or whatever else you might suggest.
CC'ing also tmb as this may be a kernel issue.

Installer boots in text mode, with a help screen.
There type "text" and enter to continue in text mode, also in stage 2.
There are also other options described, i.e passing parameters to kernel.

A way to investigate the system is to boot a live Mageia iso.
(and if you want, install it)

Thank you for information.

I tried 'text' option and seems that it workaround for me.
I found that boot menu for UEFI and MBR/legacy has differences.
UEFI menu not contain "text" option.

I find it convenient to have multiple images on flash, so I use bootflash with grub2 and iso-images, instead of "dd if=iso of=flash". 
Live image freeze and boot fail under such conditions.
In addition, the live image does not allow to perform a full custom installation.

grub.cfg example from flash:


-----------------------------
menuentry "Mageia 7.1 x86_64 netinstall nonfree" {
 loopback loop /iso/Mageia-7.1-netinstall-nonfree-x86_64.iso
 linux (loop)/isolinux/x86_64/vmlinuz audit=0 quiet noiswmd logo.nologo mitigations=off text
 initrd (loop)/isolinux/x86_64/all.rdz
}

menuentry "Mageia 8.0 x86_64 xfce" {
    echo ooo
    set isofile="/iso/Mageia-8-Live-Xfce-x86_64.iso"
    set mlabel="Mageia-8-Live-Xfce-x86_64"
    search --no-floppy -f --set=root $isofile
    loopback loop (hd0,1)$isofile
    linux  (loop)/boot/vmlinuz iso-scan/filename=$isofile isofile=$isofile isoloop=$isofile isofrom=/dev/sda1/$isofile lang=ru_RU audit=0 root=mgalive:LABEL=$mlabel noiswmd rd.luks=0 rd.lvm=0
    initrd (loop)/boot/initrd.img
}
-----------------------------

p.s. In my opinion the best solution is to get the video driver working, but I haven't found any solutions for this.

Does this mean that you could install the system successfully?

And - once installed, does it then boot & work correctly?

Do you mean multiple images of installation ISOs, or multiple 'installed' systems?
What happens if you boot a Live ISO (say USB) independantly? Does this freeze?

>>> Does this mean that you could install the system successfully?

I haven't tried going all the way with the installation, but I trust you and I think I can. 

>>> And - once installed, does it then boot & work correctly?

I used livecd(ubuntu)+rsync for copy Mageia form old laptop to new laptop and it working correclty after copied. (updated Mageia7 too).

>>> Do you mean multiple images of installation ISOs, or multiple 'installed' systems?

I mean usb-flash with multiple ISO images for purpose installation/repaid OS.
https://wiki.archlinux.org/title/Multiboot_USB_drive

>>> What happens if you boot a Live ISO (say USB) independantly? Does this freeze?

>>> dd if=Mageia-8-Live-Xfce-x86_64.iso of=/dev/sda

I haven't tried.

Black screen. Freeze or incorrect termination.

----------------------------
Summary:
1) netinstaller not working in graphic mode with amdgpu. WA  - use text mode.
2) official image not working in graphic mode with amdgpu. WA - use text mode.
3) livecd must work, but does not allow to select a packages.
4) livecd not support multiboot USB drive (support only dd method).
5) grub menu UEFI not contain 'text' mode option. WA - use edit for append 'text' option in grub menu.

Thank you for these furthe explanations.
If you have a working system installed on the machine with the troublesome amdgpu graphics, please can you post the output of:
 $ inxi -MSGxx
to describe the system, especially the graphics.

> I mean usb-flash with multiple ISO images for purpose installation/repair OS
I am not sure whether our ISOs should be expected to work in this exotic situation.

CC'ing Martin for his view before assigning this.

Thanks.

We have a section on the Wiki about multi-boot methods:

https://wiki.mageia.org/en/Installation_Media#LiveUSB_MultiBoot_Methods_.28verified.29

but I think it is a bit out of date. There is a new contender, Ventoy, which other people have reported works with the Mageia ISOs. I did submit a patch for multibootusb that made it work, but that project looks to be abandoned now.

So it can be made to work, but it's not something we directly support.

Thank you Martin.
What about the starting problem of the installer vesa driver not working with the graphic card in question? Just say "alas, there is always some hardware which we cannot install on?" Or in your experience, should it?

It may be a case of too new hardware for the Linux kernel on the Mageia 8 ISOs. Cezanne is the code name for the GPU in the Zen 3 generation of APUs. The Mageia 8 netinstall works fine on my laptop with the previous generation (Zen 2) APU. Try the cauldron netinstall ISO to see if that works. I believe it is possible to use that to install Mageia 8, if you point it at the right repository.

Hi Martin,

>>> Try the cauldron netinstall ISO to see if that works. I 

I tried.
1) iso image has incorrect configuration of file /etc/nsswitch.conf
  "hosts:" not contain "dns", consequently dns lookup broken.
  if hotfix this issue, that image https://mageia.ip-connect.info/distrib/cauldron/x86_64/install/stage2/mdkinst.sqfs and ... the result is exactly the same as Mageia8

>>> The Mageia 8 netinstall works fine on my laptop with the previous generation (Zen 2) APU

Please specify your screen resolution just in case. Because my resolution 2240x1400 not standard for VESA. https://en.wikipedia.org/wiki/VESA_BIOS_Extensions

Thank you Martin. This is very probable; I wondered likewise, but do not have the H/W knowhow that you expressed. Sign off from from the bug if you wish now.

The screenshot attachment is useful evidence.
It is no panick that Mageia 8 installer does not work with very recent graphics hardware. But it should for Mageia 9, so changed version to Cauldron.

Assigning to 'tools' re the Installer.
tmb is CC'd re the kernel/driver aspect.
