https://bugs.kde.org/show_bug.cgi?id=463716 --- Comment #1 from betami...@posteo.de --- I have tried narrowing down what the issue might be and have found that adding "intel_iommu=on" to my kernel's boot options causes it to happen in 100% (or close to that) of the cases. My normal boot options are: "options root=PARTUUID=XYZ zswap.enabled=0 rootflags=subvol=/@ rw rootfstype=btrfs processor.max_cstate=9 intel_idle.max_cstate=9 nmi_watchdog=0 nowatchdog mitigations=off intel_iommu=on kernel.kexec_load_disabled=1 audit=0" I am able to reliably reproduce the crashing, but the coredumps are close to 16MB (10MB for kwin_wayland and 6MB for Steam's webhelper). The bug shows up regardless of whether I am using linux kernels 6.1.1-zen as well as 6.1.1-cachyos, and now "6.1.2-3-cachyos". -- You are receiving this mail because: You are watching all bug changes.
