Seeing this when looking at journalctl -b:
$this->bbcode_second_pass_code('', 'Jan 01 00:00:02 ubos-bbb kernel: WARNING: Your 'console=ttyO0' has been replaced by 'ttyS0'
Jan 01 00:00:02 ubos-bbb kernel: This ensures that you still see kernel messages. Please
Jan 01 00:00:02 ubos-bbb kernel: update your kernel commandline.')
Where's the kernel command-line anyway? My uEnv.txt only says:
$this->bbcode_second_pass_code('', 'optargs=coherent_pool=1M')
