Created attachment 878397 [details] dmesg content Context: I launched libreoffice and got this kernel NULL pointer dereference. This was brought to my attention by a "soft lock up" message. Sadly, I didn't save it. Let me know if I need to report this elsewhere. Quick googling wasn't success in finding this bug already reported. The attached file has more dmesg content [181771.785131] amdgpu 0000:04:00.0: amdgpu: bo 0000000061596dee va 0x0800000000-0x0800000001 conflict with 0x0800000000-0x0800000200 [181771.785137] amdgpu:

Similar reports indicate that bad memory might be a cause. Can you run memtest?
Memtest86+ ran overnight. No errors in almost 10h of testing. Yesterday I opened libreoffice and the same bug was triggered. I am now on 6.6.6. Today, I did a trace with drm debug at a high debug level, using the instructions at https://gitlab.freedesktop.org/wlroots/wlroots/-/wikis/DRM-Debugging
Created attachment 879006 [details] dmesg with DRM debug 0x19F
For the past month, using the latest kernels I can no longer trigger this bug. It has most likely been fixed upstream.
