Thanks, no worries! I got myself confused too. :) The config you sent looks like I'd expect now too. Questions for you, if you have time to diagnose further: - Are you able to catch the very beginning of the crash, where the Oops starts? - Does pstore work for you to catch the crash? - Can you try booting with this patch applied? https://lore.kernel.org/lkml/20230629190900.never.787-kees@kernel.org/ I'll try to see if I can figure out anything more from the images you posted. -Kees -- Kees Cook
