Update from me: I can't reproduce the splat in 5.19.0-rc4. Not sure if it's already fixed though, since it happened randomly and I didn't realize what action provoked the splat. I am running Ubuntu 22.04 for my daily desktop activity. I'll keep my lockdep on and will send you update if it's still triggering. -- Ammar Faizi
