If it goes through a full reboot cycle then there should be no
difference from one boot to the next as not much should hang over from
one boot to the next. I wonder if you have a hardware problem, though
the fact that they work in grub tends to suggest otherwise. I think
you said earlier that if you ask it to reboot then it does. If you do
this does everything work every time?
