I didn't get a lockup with my AMD ATI R7 workaround but there was a momentary freeze when the i915 driver screwed up again.
So after that happened I tried the linux-lts ... Sadly I can't use that one because my wi-fi device crashes on startup:

Oh well.

Since you're at the mercy of an incompetent Linux kernel team (I don't know what the hell Linus thinks is going on) all I can suggest is taking a stable LTS kernel from Red Hat/Ubuntu/etc (whoever has the installed base to find problems quickly and the manpower to apply custom patches) and using that as the Solus LTS.

      appmath Not sure if "incompetent" is really the right word... I'm guessing the whole kernel thing does come with a certain complexity.

        DataDrake Thanks for that post. Lots of insights there for a noob like me 😁 Funny enough 5.4.8-141.current is the first current kernel that works flawlessly on my XPS 9370. Until now I stayed on the LTS kernel but that has a problem with bluetooth on my machine.

          can confirm the lockups on Gnome Edition as well with 5.4. Booting previous 5.3.18-140 for now - no issues over there....

            [deleted]
            I've had to return to 5.3.18-140 as well since my attempt at a workaround (using my discrete gpu) failed. I suppose blacklisting the i915 driver would be the next thing to try but I find myself unmotivated to do that.
            So for the first time I find myself running a FrankenSolus - up to date but downgraded to the previous linux-current, -headers and virtualbox.
            So far so good...

                appmath How did you get the headers for 5.3.18-140 ? I only installed the kernel but could not find the headers. And why rollback the VirtualBox as well? FrankenSolus...lol ! 🤣

                    elfprince
                    I rolled back Virtualbox because when you install it manually you generally have to rebuild the kernel modules using dkms - not being sure how Solus does it (haven't had to worry about it, Solus just works), I wanted to be safe and not sorry. 99%+ of the time we get the kernel, headers and virtualbox updated together.

                    The current headers probably aren't necessary since I'm not manually building drivers atm but I wanted to keep my FrankenSolus at least somewhat consistent with how the upgrade process goes.

                    • linux-current-headers-5.3.18-140-1-x86_64.eopkg

                      Thanks, but headers don't seem to exist.
                      $ sudo eopkg it linux-current-headers-5.3.18-140-1-x86_64.eopkg

                        DataDrake just to throw that in here randomly if its okay.
                        The last update with 5.4 is actually the first kernel update that gave me problems on my Solus machine. The entire System "feels" unstable, some tasks don't close as fast as they used to and/or make the system "stutter" while the task is getting closed/killed.

                        Also I've graphic glitches in some games with this Kernel. I can't tell if this has anything to do with the Kernel or if its an Nvidia driver issue. But with the latest 5.3 kernel those problems do not happen at all. I am using a Ryzen 1700+ btw. with a 1080 nvidia.

                        Edit: and also the budgie-wm process has unusual very high CPU load hovers around 8% when idle and goes up to 60 or 70% when I do some simple stuff like using nautilus windows or Firefox etc. That is also the reason it seems, for the "stuttering when closing tasks" my fans go crazy because CPU load goes up like crazy and then everything slows down becaue budgie-wm process takes all the CPU.

                          Looks like it is kernel related (rather than NVidia driver).
                          My machine is running internal GPU (intel 620) only, and I am getting the GPU panics as well.

                          I also can attest that 5.4.x kernels are giving me unstable system. Intel video

                          Mouse moves, picture is frozen, I can ssh in and reboot. Sometimes I can switch to other tty e.g. with ctrl+alt+f3, other times switching is very slow or not happening at all.
                          Noticed that electron-based(?)/gpu accelerated(?) software, like opera/chrome, spotify, vscode sometimes starts to flicker and becomes unusable.

                          Since I can choose to boot 5.3.x, I use it. So far it works without problems.

                          5.4.12 brought back my troubles as well while 5.4.8 worked nicely. Not sure if it's really the kernel itself or some incompatibility though. My knowledge of these things is very superficial.

                          The 5.5.1 kernel is coming soon and may have fixes if enough people reported this issue to the kernel developers.

                          I had the same problem with kernel 5.4, 4.9 works nice but wifi/ethernet drivers are not working properly with it.

                            Justin Yes, It happens although lockups are not random, It happens when the laptop is under heavy load.

                                Justin I don't think I get out of memory nor hammering the CPU. If I run all those things(Godot development in VSCode, Discord in firefox and nautilus) at a time in 4.9, it only covers 4 GB(out of 8GB) ram and 40% of all cores.
