I saw the same thing myself.  It turns out, though, that I was using 

COPTFLAGS= -march=pentium -Os -pipe

to compile my kernel.  When I used the stock opt flags of

COPTFLAGS= -O -pipe

to compile my kernel, my machine booted OK.  It appears as though some
changes were put in the tree that are sensitive to optimizations above -O
-pipe.  My machine never behaved this way before with high optimizations
until the new changes were put into -current about 1 or 2 days ago.
