You think it may be a kernel bug ? It happens in Fedora, Ubuntu 19.10 does not have this.

I don't know that for sure since I am not familiar with lvconvert. But,
the fact that it is hanging while doing its job suggests that it is a
good place to start.

This says that lvconvert can't complete because it is waiting for a
resource that is locked. Something else has that lock, and it seems
to be something in the lvconvert chain, or it would be released and
lvconvert could complete. This is known as deadlock, and is a resource
contention error, and usually is a bug.
e.g. A starts and runs, and triggers B to run. B grabs a lock on
resource X while running and then waits for completion of A in order
to finish. A gets to the end of its tasks, and needs a lock on resource
X to finish. But B has that lock, and is waiting for A to complete to
finish and release X. =><=
