Our Observation :
As seen above if booting is successful, log message "Starting udev" is getting printed immediately after "INIT: version 2.88 booting". (Highlighted in RED above)
if booting is failed, log message "INIT: Entering runlevel: 5" is getting printed immediately after "INIT: version 2.88 booting". and a none login is getting appeared.(Highlighted in RED above)
What could be the possible cases for this occurrence.
Thanks in advance.
