I have firmware 13 on the GE module :(

The PR29528 is JunOS, not firmware related and we're already running 7.4R2.6

I have two coredumps in /var/crash .. but i dont know how to "read" or
debug them.

Also i notice another strange thing... a "show chassis craft-interface"
shows

|Up: 19+07:48:31     |

but i really dont know where this 19 days are coming from. The RE has a
uptime of 69 days and both, the FPC and FEB rebooted yesterday evening...
