pingu8 has these specs:
PRIME TRX40-PRO AMD Threadripper PCIe 4.0 ATX Motherboard
Ryzen Threadripper 3970X 3.7GHz 32C/64T 128MB Cache, 280W CPU
Vengeance LPX 128GB (4x32GB) DDR4 3200MHz Memory
GeForce RTX 3070 TUF Gaming OC 8GB Semi-Fanless Graphics Card
TBS 6205 Quad Terrestrial HD Low Profile PCIe TV Tuner Card DVB-T2
After the ultimately successful upgrade of pingu7 to Mageia 9, I decided to upgrade pingu8 as well.
The upgrade seemed to go OK and booted up into the desktop, but then the window manager seemed to crash (taskbar disappeared, desktop icons disappeared and desktop background went black). It came back again a few seconds later, then crashed again. After a third attempt, it stayed down.
So I have no taskbar, no desktop icons and a black background.
The second root partition still has a working Mageia 8 installation, which I am using to post this.
Attached is the user and system journal output (I copied /root1/var/log/journal/.../system.journal etc.
to pingu8 to run the Mageia 9 journalctl on it).
On pingu7 running Mageia 9, ps axuww shows:

On pingu8 with the window manager not running I get:

---------------------- second attempt to update by copying from a similar machine --------------------
[NB: Not sure if this section should be a separate thread, or just removed as "unworkable". Please advise!]
I decided to try to grab a copy of the working root partition from pingu7 and put it on another backup root partition on pingu9 (mounted on /root3). I copied it over using rsync from pingu7:
- Code: Select all
rsync -axvDXH --delete --exclude /boot/grub2 / pingu8:/root3
I replaced /root3/etc/fstab with the proper fstab for /root3 and updated /boot/grub2/grub.cfg to load the correct vmlinuz and initrd: /boot/vmlinuz-6.6.116-desktop-1.mga9 and /boot/initrd-6.6.116-desktop-1.mga9.img
This "rsync" method worked for copying the working Mageia 9 installation on pingu7 to backup root partitions on the same machine (which can be booted successfully).
On booting to root3 it seems to hang after the usual BIOS error messages, with none of the usual startup messages and no desktop.
journalctl is attached (system.journal-root3.txt)
Please use code tags. ~Germ
