this breaks booting debian with systemd for me:
[    4.632197] systemd-udevd[90]: Starting version 241
[    4.639324] systemd-udevd[91]: Failed to create udev control event 
source: Operation not permitted

"env delete console" and it works again.

The device tree already has 'stdout-path = "serial0:115200n8";' btw.
