I've tested the following releases for upgrades:
03.16.01a.S/03.16.02a.S/03.17.00.S, all have the same bad behaviour when 
upgrading to 03.18.00.S.
I guess the problem really is with 03.18.00.S itself, because it will 
also shut down some 10GE ports when
you erase the startup-config starting fresh with a reload, when normally 
all ports are no shut by default.

It could have to do with the dual-rate 1G/10G ports, as on the 
ASR-920-12CZ-A we didn't have a problem when upgrading.
(they have two 10GE only ports, no 1G SFP work in those ports)
