Well, the bash is what turned off the logging, and the logging started at
619.xxx and ended at 633.xxx so that's ~14 seconds of logging. So I would
assume you did it in the right place.
How long does the stop happen, and what exactly freezes? Can you ping the
machine? Also, have you tried to switch to a console before it freezes,
and see if it doesn't freeze that. I'm curious if X isn't waiting on
something.
