I have managed to find an old livecd image from june 2025, and I have installed it. I have not installed nor updated any package yet. I could update each package until the problem occurs again, so that we would know which package causes it. Would this help? What packages should I upgrade and in what order? Do you have suspicions?

I believe the AI is misleading you: I have removed nvidia_470 and nothing changed, except for even worse performance, because of course now everything is cpu rendered

glxinfo | grep "OpenGL renderer"
OpenGL renderer string: llvmpipe (LLVM 22.1.5, 256 bits)

I don’t know if any of the uploads was successful because I am told I am not allowed to upload those file types.

unfortunately it did not help

Got this using strace -f -o kate_crash.log kate -n (compressed with zstd)

The reason I suspect some shared library is that non-openmamba software (edge, vscode…) are not crashing despite having bad performance. These come with a bunch of statically linked libraries.

Another solid test would be to have an older version of openmamba at hand to install, but I don’t have that. I do have windows installed too, and that one is working fine (fine by microsoft standards).

Hi thank you for the reply. I also discovered this one

$ LD_PRELOAD=/usr/lib64/libthread_db.so.1 kate -n
kate: symbol lookup error: /usr/lib64/libthread_db.so.1: undefined symbol: ps_pdwrite

rpm -V libQt6Core returned nothing. rpm -qa | grep -E "^libQt6|^qt6" | sort showed all 6.11.1-1mamba

sudo dnf reinstall libQt6Core and rebooting didn’t change the situation

I can get kate to crash consistently when any scrolling (horizontal/vertical) happens, I am testing with that

I could let memtest run overnight but I am more suspicious of some library over the hardware being faulty

[einar.hjortdal]

It probably isn’t libQt6Core, after a reboot crashes keep happening but libQt6Core errors aren’t present in dmesg yet

[einar.hjortdal]

Could it be libQt6Core? dmesg -T is full of drkonqi-coredum[17665]: segfault at 0 ip 00007f4db46345c3 sp 00007ffe25cce738 error 4 in libQt6Core.so.6.11.1[2345c3,7f4db44c2000+457000]

Even kate crashes when opening the openmamba-report file. Performance is abysmal, bluetooth crashes too. Something for sure is happening. Surprisingly, nvidia_470 is working fine this time

Although, after the update, plasma and kwallet kept crashing. I was not sure if I caused this mess so I have re-installed openmamba using the livecd image.

I noticed that plasma cannot open the menu widget in the livecd image and Calamares crashes at the end with a “installation failed” message. Despite that, after rebooting openmamba appears to have been installed correctly. The menu widget still does not open.

After dnf upgrade, I am still getting the same crashes. Therefore I do not believe I caused these issues myself.

[einar.hjortdal]

Got it, that was correct. I removed all i586 packages and the update proceded correctly. The repo was indeed disabled

[einar.hjortdal]

Fixed, thanks

[einar.hjortdal]

Edge is actually available as rpm here, however I do not like how it is packaged.
