Description of problem:
When attempting to boot Fedora-IoT-29-20181021.0.aarch64.raw.xz on the Raspberry Pi 3, error messages are repeated during the boot:

How reproducible:
Most of the time. The system does boot to initial-setup.

Comment 1 Paul Whalen 2018-10-31 19:58:11 UTC
Goes away when all consoles are removed from the kargs, output is correctly displayed on the serial console.

Comment 2 Peter Robinson 2018-11-17 01:07:14 UTC
This was console options conflicting with bluetooth and is now fixed in IoT nightly builds.
