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.
