One thing to note is there are no hardened parts to use ulsd. The 5521s has the latest updates but unless something snuck past me nothing is hardened.
Something I realize just now reading your signature is that you have a #9 resistor and I remember now I don't have a resistor in the connector on the new PMD. I have a #5 and #9, I will install the #5 tomorrow and see if it makes any difference.
