I got a mail off list which pretty much explains it :) fpd version 1.17 seems
to affect tengig 0/0/2/2 and 0/0/2/3 (Which are the ports i moved the link between).
The IOS XR 5.3.1 contains 1.18 BUT - somebody updated this machine without
reading the multi-page-update-description which mentions "fpd auto-upgrade". So
nobody updated the fpd to match the current IOS XR - so - although 5.3.1 is 
unaffected by the bug - this machine still is due to incomplete upgrade.
