Bug 511541

Application: plasmashell (6.5.1)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.0
Frameworks Version: 6.19.0
Operating System: Linux 6.17.6-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.5.1 [CoredumpBackend]

-- Information about the crash:
I've recently had a problem where my notebook would no longer wake from suspend and I had to force-shutdown the entire system. This caused the entire BTRFS filesystem to go kaput.

After that FS destruction I went ahead and re-installed OpenSUSE Tumbleweed from the latest ISO for x86_64 and then went ahead to restore my entire system from a two day old backup which restored all of my important files and my kde settings.
Now to the current situation: plasmashell keeps crashing at random with me not doing anything. No matter if I'm browsing or just letting the system idle. Plasmashell crashes.

I have since checked every single component of my X390 Yoga Thinkpad. I've ran a full SMART check on the SSD, which has a mere 17 TBW on a 2TB disk, so only 8.5 DW and shows no signs of wear.
The CPU is idling at a cool 35-40°C and tops out at ~80°C running memtest on all cores. And memtest finishes without errors for several full passes. I'd be willing to bet 50€ on the hardware being in perfect condition.

One thing I remember is having run updates on the day the escapades started. Everything from the lock-up to the FS corruption to now. I don't have conclusive evidence to properly suspect the update, but it just seems too... fitting.

Further specs of my notebook:
 - 16GB LPDDR4 from Micron (soldered)
 - Intel Core i5-8365U (4c 8t 1.6GHz)
 - KINGSTON SNVS2000GB 2TB NVMe SSD
 - Kernel 6.17.6-1-default
 - OpenSUSE Tumbleweed 20251031
 - Plasma ver. 6.5.1
 - Wayland (Going to X is not an option due to lacking touch support)

Please help. I am getting frustrated and cynical.

The crash can be reproduced every time.
