Hi all,
I am new to linux, so please don’t judge too harshly.
I have recently updated to Fedora 42, and I have noticed a pattern: when I use alt+tab to switch between windows, there is a small chance that the entire system will crash. I haven’t noticed anything specific, but journalctl -b -1 -p3 consistently gives the following last errors:
Apr 25 18:04:54 fwrk kernel: amdgpu 0000:c1:00.0: [drm] ERROR dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data

Here is the software/hardware that I use:
I wonder if anybody else has this problem (and if they were able to fix it)
I suspect you may be having the same issue as me: Framework Laptop 13 locking up on Fedora 42 with Wayland+GNOME
I tried switching to KDE Plasma, and it seemed to work, although personally I hate the look/feel of KDE. Today I’ve been trying GNOME-on-X11 instead of GNOME-on-Wayland and I haven’t experienced hangs so far. I’d try GNOME-on-X11 first before trying KDE Plasma if I were you: you should be able to switch at the login screen by clicking the little gear icon in the bottom right of the screen once you select your login user.
Update: I’ve been using GNOME-on-X11 for many hours today and it hasn’t crashed or hung once, so this definitely seems to be specific to GNOME-on-Wayland. Other DEs that use Wayland work, so it’s some interaction between GNOME and Wayland specifically, possibly due to updated AMD drivers.
The downside of GNOME-on-X11 is that they haven’t implemented touch gestures for most things, so it’s not a great downgrade, but it does at least not crash or hang.

Thanks for advice! I’ll try both methods and see if they work for me as well!
Yep, changing to KDE solved the issue: no more crashes. I actually like KDE more than gnome, so thanks for suggesting me that. I tried to highlight your reply as a solution, but for some reason I don’t have the permissions to do so ¯_(ツ)_/¯
