Fw13 Ubuntu HX370 freezes need help

[Josef_Rezek]

Hi,
just received my new AI HX 370 mainboard and did the HW upgrade from amd 7040u.
The old config worked out of the box, so I just updated the firmware and the os Ubuntu 24.04 and swapped the boards and loaded up new setup.

Everything looked nice until first freeze happened.
Description: screen content freezes. Audio keeps playing, mouse cursor keeps moving and even reacts to the underlying elements, eg changing to arrows when you arrive at the window border. But no input is being processed. Only hard reset by holding the power button works.

Steps taken:
I red that the Ubuntu is not officially supported, which puts me in a hard place. I was using the ubuntu over a year and there is a lot of stuff. So I searched the forums and upgraded through 24.10 to the Plucky of 25.04.
No luck still getting freezes. Sometimes after 3 minutes.
So I disabled secure boot and used Mainline to try various kernels from the 6.14.7 all the way to the most recent 6.15.2
Still no luck, still getting freezes to the point I cannot use the laptop.

I am about to give up on this mainboard but before a refund I am willing to jump the Ubuntu ship and try some supported distros. But I don’t want to lose the data or migrate them. So I need help how to easily swap the distro while keeping the data. I would argue that if FW has this great product of swapping mainboards they should at least provide a painless guide on how to switch distros if hey cannot maintain compatibility.

Edit: today experiencing 8th freeze already
Probably looking for switch from Ubuntu 25.04 to Fedora 42

I asked ChatGPT for guidance and it provided mostly correct answers.
I used gparted to shrink some space on my other partitions and created two ext4 new ones:
/home and fedora
identify UUID of the /home partition:
-lsblk -f to

mount new partition temporarly:

sudo mkdir /mnt/newhome sudo mount /dev/nvme0n1p8 /mnt/newhome

• replace /dev/nvme0n1p8 with your partition

sync the /home folder with the mounted partition:

sudo rsync -aAXv /home/ /mnt/newhome/

create new mount point:
sudo mkdir /home
added the new mount in fstab via nano editor:
sudo nano /etc/fstab

adding line at the bottom of the file:
UUID=abcd-1234 /home ext4 defaults 0 2

mounting everything:
sudo mount -a

After reboot you can verify with:
mount | grep /home
It should produce something like this listing new partition as the source:
/dev/nvme0n1p8 on /home type ext4 (...)
Also check that the new /home/ has correct permissions:
ls -ld /home/yourusername

After all these steps I had separate /home partition that can be used across all distros.
I am used from Windows that on one partition I have the OS and on another the Data, however I was not aware how to implement same strategy for Linux OS.

With this setup I was able to install Fedora 42 using Live image installed via MeadiaWriter recommended by FedoraProject. I was sure to designate the new empty partition for Fedora and mounted the /home and /boot/efi partition with no formatting during the installation and set up new user with the same username as in Ubuntu

Also I must say I was incredibly lucky, as I was experiencing freezes almost every 5 minutes and like right after I finished resizing the partitions or right after migrating the /home.

So be smarter than me, and if you plan on upgrading your mainboard, do this preparation on your old mainboard and install the supported OS before the swapping for the new mainboard.

Also I did not experience any freeze on Fedora 42 so far.
