I had already done it and from what I could see until now, it doesn't change
anything if it is a cold or a hot boot. Just in case, after your comment, I did
it again and it still ended hung (3.13-rc3 with all spread spectrum disabled).
It happened before that my system would not hang for some reason once in many
boots, maybe that's what happened.
