Created attachment 117692 [details] Full kernel log - line 5251 SUMMARY Wayland session crashes and goes to a black screen requiring a reboot The kernel logs mention org_kde_powerde and org_kde_powerdevil STEPS TO REPRODUCE 1. Use the wayland sessions normally. Issue seems to happen randomly. OBSERVED RESULT The whole wayland session crashes and you are brought to a black screen, which shows no response to keyboard input. Kernel logs show that the kernel is still at least recognizing REISUB (i had it disabled at the time though so i couldn't use it), so i don't think it's the problem. EXPECTED RESULT Wayland session does *not* crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: Antergos with 4.14.5-2 (happened once) & 4.14.90-1 (happened twice so far) (available in About System) KDE Plasma Version: (for 4.14.90) KDE Frameworks Version: 5.54.0 Qt Version: 5.12.0 Kernel: 4.20.4-arch1-1-ARCH ADDITIONAL INFORMATION I'm using a RX 560 (AMDGPU) and a Ryzen 5 2600 cpu (Motherboard is a MSI B450M Gaming Plus with current bios (7B87v13 and AGESA Code 1.0.0.6) Attached is the kernel log (at around line 5251 is where the issue seems to start)
>Jan 27 14:10:18 brian-ryzen systemd-coredump[8683]: Process 7069 (kwin_wayland) of user 1000 dumped core. Kwin crashed. Kwin crashing just makes everything quit. From a powerdevil POV, it's not a bug, so I'll close this. We still have a kwin crash. Do you remember what you were doing at the time? Ideally we also need to get a backtrace.
I have not been able to reproduce it yet unfortunately. It's very random. I was in spotify at the time switching a song, and then i went and minimized the window and opened dolphin. Further, i'm not really sure how i could grab the backtrace?
