I haven't found any matching public bugs on bugsearch.
I guess I'll have to open a TAC case soon.

Hi all,
since a few of you seem to have ASR 920 deployed, a word of warning about
upgrading to 03.18.00.S/15.6(2)S:
- upgrading from a previous image might lead to some or all of your four 10GE
uplink ports being put in admin shut down state which is reflected in
running-config as well as startup-config after the upgrade.
This could lead to unreachability if you use those as backbone links and don't
have an OOB console. Even a physical power off/power on won't help, as it's
written to NVRAM.
You will need to re-activate the ports on the CLI with no shut. Subsequent reloads don't
seem to be affected, so it's just the upgrade that's flawed. (Might have to do with the
removed "license feature port bulk" command).
- removing a transceiver from one of the four 10GE uplink ports will put the
interface in admin shut down:

So just replacing an SFP+ will need a CLI intervention (no shut) to get it
online again.
This change is just affecting the running-config, a reboot will bring back the
old state (no shut).
This behaviour can be easily reproduced on a ASR-920-24SZ-M model, but might
also impact other models.

Chris
