This happens when I turn on the scroll lock some time after "Creating
and/or trimming log files" is printed, but before the vty login prompts
At this point I can't use the vtys (login, switch). CTRL+ALT+DEL seems
to properly restart the system. But if I wait for 30 seconds, a login
prompt finally shows up.
The things to note is that (1) the text from the scripts never got
printed, and (2) the system should have been loaded in 2 seconds, not 30.
