Starting Network: lo0 em0 em1 lagg0. However, about 70% of boots result in this: Created clone interfaces: lagg0. em0: link state changed to UP em1: link state changed to UP [hang] When doing Ctrl-T at this point I get: load: 1.51 cmd: ifconfig 606 [*in6_multi_mtx] 17.80r 0.00u 0.72s 0% 1940k >How-To-Repeat: I have a second box (different board, also with em-Interfaces) with the same behaviour. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
