I'm able to reproduce this on a Focal 5.4 kernel by sending data to a Pi

Raspberry Pi OS running a 5.4 kernel. I recompiled the Raspi OS kernel

Sorry for the late reply. That kern.log doesn't help much since it
doesn't contain any of the errors mentioned above.
>From https://github.com/ROBOTIS-GIT/turtlebot3/issues/593 it seems that
18.04.3 works but 18.04.4 does not? Is that a true statement?

Sure. I have attached the most recent one.

Reportedly this was not an issue with 18.04.3, although I cannot say I
have personally tried this.
