If I had to guess (and I do) I'd say one of your shutdown scripts tried
to grep thru something in /proc and the module that once supplied the
data for that something is gone, without having removed its /proc
entries. Lacking any particular insight on what module to blame, I'd
start by disabling various modules and booting cleanly so they never
load. Binary search your way thru them until you find the culprit.
