Hi Ted and Davor,
Thank you for confirming this. This means the netdev trigger no longer
works in 3.12 on or after. When use with APU led driver, the problem
already shows. It is not APU led driver problem alone but is netdev
trigger.
I would remove netdev trigger from the time being.
Regards,
Punky

If you are seeing network hang-ups during boot on an WRAP/ALIX/APU

VOYAGE_LEDS="NO"
Sorry I don't have a better fix.

Here is the console output captured trying to enable the netdev
trigger on the ALIX.
