Call me stupid, but I can only find the trace and linked to unreadable
google sites that wan't me to log in somehow and no actual details.
If you have a direct link to the reproducer (an attachment would do
it as well) I'd love to try it myself.
Otherwise this commit in the block-5.15 tree should help to catch what
I suspect is the root cause (final ref drop before unregister) earlier
and with a better backtrace:
