We changed a router card, and now we're seeing PSE on both ends.  If the 
E3 card is stronger, I can accept that we're overdriving the carrier's 
gear, causing issues to be seen at the other end, but if we follow the 
same logic shouldn't the card also _accept_ a stronger signal (and 
therefore not take PSE due to the wider margin)?

This is the only link in the card.  Problems were the same whether it 
was in port 0, port 1, or as currently in port 2.  I've also gotten an 
offlist response which showed me how to adjust the timing sources at the 
card level.

We're seeing OSPFv3 issues that seem to coincide with times when the PSE 
rate is perhaps highest.  We're also seeing far more than the Cisco 
troubleshooting doc says is allowable, figure a million per day.
