Welcome to the Ryzen world , I fight with those freez since the first day i bought a Ryzen laptop and installed linux distros. Same issue,
https://discuss.getsol.us/d/11228-how-to-load-amd-ucode-stored-on-boot
I can solve it using Arch but not Solus, on Arch I'm able to change amd-ucode.img and load a different one and I installed a C6-Disabler too available in AUR https://github.com/joakimkistowski/amd-disable-c6 but not available on Solus repo.
On Solus sadly I can't solve the issue so I use it only as "emergency" OS installed on other partition just in case my arch OS doesn't start.
And yes if freez happens updating OS can be a problematic situation, I agree.
On Solus you can only

  • try installing AMD microcode and pray there is a new version for your SoC.
  • wait for a new kernel hope it solve for you

This is why Pop Os still is on kernel 6.9. They are waiting for a proper fix before they introduce a newer kernel.

    Thanks for the insights!

    My Ryzen always did very well with the most current Kernel.
    I somehow managed to install the LTS Kernel without a freeze. Testing it out now. Looking good so far.

    Oh, do you have a link with info about that?

        It must only affect Ryzen laptops as I'm on a Ryzen stationary and doesn't suffer such behavior.

        Staudey This is from the cosmic channel on Mattermost:
        Generally, Pop!_OS does upgrade the kernel and Mesa to fairly recent versions, but newer kernels have some bugs (notably amdgpu), which might be why it hasn't yet been updated (there were pull requests for 6.10 and 6.11, but they weren't merged due to regressions).
        As for Mesa, it's probably lower priority than COSMIC, and they might not yet have hardware that requires newer Mesa versions, so it's on 24.0.3.

            No luck with newest LTS Kernel 6.6.66. Just had two freezes in a row 🙁

            Any logs I could check? Anything else I could do besides waiting for bugfixes?

            In BIOS setting you can see if your BIOS present a entry like GLOBAL-C STATE CONTROL or COOL&QUIET and disable it and try use your pc and see if this solve or not.
            Generally disable C6 state solve issue on ZEN1 , ZEN+ and ZEN2 and you too is using a zen+ cpu as me
            I don't have entry on BIOS on my Huawei laptop so the only solution was finding a distro with a C6 Disabler on the repo and is a ARCH based distro, but if you have the entry in your BIOS probably disabling C6 will solve and you can use Solos.
            You can see if there is a BIOS update for your machine and if there is a update do it.
            If the trick does nothing for you and still continuing freez then reactive C STATE on BIOS
            In case it works this is simply a workaround, because one thing is only disabel C6 State (with a app or a setting after boot) and a different thing is disable C STATE at all as set it on the bios that cause your machine stay at maximum freq all the time. But if it solve and you have no more freez is better than nothing, and probably if needed we can see id Solus dev can insert a C6 disabler trick on the repo.

              tflovik The release with kernel 6.10.13-304-1-x86_64 was the last one that worked for me.

                Romagnolo73 Thanks for the info! My BIOS is already up to date. I will look into the C State Bios settings.

                  5 days later

                  Someone found a way to reproduce this craziness:

                  I believe I've found a quick way to reproduce the issue. I use i3; I start two terminals in one workspace, and hold Super + Shift + Space on one of them, which rapidly alternates it between a floating window and a tiling window, producing a lot of graphical window resizing. This can produce a freeze on broken builds in a few seconds.

                  Please open an issue (if there isn't one already) on our bug tracker for this. By opening an issue, it will allow our developers to look into it and keep track of progress. Thanks.
