I'm not sure why so many people (so far) seem to think that this problem
is always the same issue -- it isn't.  There are multiple things that
have historically (and/or presently) have caused this issue.

Here's the list I composed only a few days ago, and it is far from
thorough:

My point is that the "shutdown -r issue" issue might manifest itself in
the same fashion for everyone, but the **root cause** often differs.
I.e.  what fixed it for you may not fix it for Adam.  We must wait and
see (he's in the process of getting a system to try stable/9 on).
