Since I started rebuilding ports yesterday, I've been hit by this panic
(copied from a low-res camera):

panic: moea_pvo_to_pte: pvo 0x17e6810 pte does not match pte 0x26e0740 in
moea_pteg_table

...

The svn version is r215752, I'm currently building r216254 hoping that might
fix something.  This panic seems to occur after about 1-2 hours of ports
building, so is reproducible to me.  I also have the crash dumps available
(2).
