Bug Description
it looks like systemd-udevd is crashing with the following error:
-- Boot a74cfdb7e237433

I'm not sure if this is related, or a red herring.
this is on a raspberry pi 4b 2GB that was recently upgraded from 21.04 to 21.10

acpidump:
just to clarify, before the upgrade I had /dev/ttyACM0 and a corresponding entry in /dev/serial/by-id/ for it.
I've verified that a fresh image of 20.04 LTS with the same device attached does not exhibit the same issue, and the device shows up as expected.
