'debug' on the kernel command line causes boot failure
Last modified: 2013-10-21 17:35:13 EDT
Remove 'rhgb quiet' from the kernel command line in the grub config and add 'debug'. The system will mostly hang right after it says 'Welcome to $DISTRO'.
It isn't completely dead, as I still get one log line every minute or so. But 10 minutes the system is clearly not booted and has made no visible progress. I wonder if there is a sleep 60 type line in the debug code path somewhere?
Seem that systemd's own logging gets stuck in the filled-up journal socket,
before the journal is started, and tools only log in 1/min frequency. :)
This seems to make it work for me:
systemd-207-1.fc20 has been submitted as an update for Fedora 20.
systemd-207-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report.
