We have an MX700 running TC7.3.15.a9f4c3a, when booting up we initially get the Cisco logo on both screens, but then the screens both go blank and the system does not progress any further. The touch panel is trying to pair with the codec without success.
We have pulled the attached log from the console port on boot up and always stops at :
systemd-fsck: /dev/mapper/config: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. systemd-fsck: (i.e., without -a or -p options)
