So, if I may be so bold as to make a suggestion:
Can we please modify 2008/760 to make fast-reboot *not* enabled by
default? A follow on case can be submitted to change the default
behavior later, when everyone is comfortable with it.
Sherry, if you agree with this course of action, then I'd recommend
sending a note to the case log of 2008/760 indicating this. I don't
think we need to reopen it or have further discussion about such a
change, if you're agreeable to it.
