Ah, looks fairly familiar to me.  I've got several 7507 RSP4/256M 
VIP2-50 PA-MC-2T3 combos around my network.  Two of them are connected 
to MX2820s.  One of them was showing horrendous errors (including the T3 
controller flapping; a thread here a few weeks ago has me checking 
12.0(28)S2, as I'm at 12.0(27)S3 at the moment) on the MC-2T3, but clean 
as a whistle on the mux.  A cable swap has significantly lowered the 
errors, but not completely eliminated them.  Next step is to swap to the 
protect card in the mux, and we're coming up on the window to do that.

Do you have "sh contr t3 1/0/0 tab", and if so is it clean?
