--- Comment #7 from Alex ([email protected]) --- Additional confirmation from reporter (to use all triage info): - Reproduces on stock Arch LTS kernel 6.18.55-1 as well, same cold-boot + high + immediate-GUI pattern. So NOT CachyOS/sched_ext specific (CachyOS 7.2.9 has lavd warnings, LTS does not, both wedge). - No RADV involvement: faulting CS are kitty (OpenGL) and kwin_wayland (OpenGL radeonsi raven ACO). RADV installed but idle in this repro. - devcoredump: kernel printed `[drm] AMDGPU device coredump file has been created` twice in faulty boot, but it is RAM-only and expired after reboot (nothing in /sys now). Reporter will set a udev rule to auto-save `/sys/class/drm/card*/device/devcoredump/data` on next `high` repro if you need it - please tell which artifact you prefer (devcoredump vs umr register dump vs full dmesg with drm.debug=0x1ff). - Will run memtest86+ to fully exclude shared DDR4 (VRAM is carved from system RAM) and `amdgpu.vm_update_mode` / `cwsr_enable` tests on request. Currently stable on `auto`, so can A/B on demand. - 3.9MB full journal of faulty boot retained locally (attached trimmed kernel-only 109KB due to size); can provide compressed full log or split on request. -- You may reply to this email to add a comment.
