Works ok for me. Is your power led flashing still?

Please be respectful when posting. I do this in my free time on a volunteer basis. https://lantisproject.com/blog
On openwrt 15.0.5 release build the wan led works fine.
However on latest trunk the led is not working.
The setup for the led in /etc/config/system is the same on both builds and on gargoyle.
So i think it is an openwrt bug.
My power led is only blinking during boot i think. After booting it is steady.
