I have a similar problem like the one that arrived to bikutoru on his RPI3.
On a fresh new install on Odroid C1+, Volumio crash after a some minutes and then going bootloop :
Web GUI crash (spinning wheel) and freeze. Track continue to play normally but playlist is broken. After few seconds, volumio reboots (spinning wheel and startup music can be hear), then bootloop crash every 30’’/1’.
I sent log but can’t get the logs…. because the /dev screen still indicates “sending log reports, please wait” but nothing happen
I have 3 plugins installed : spotify, youtube and Backup & Restore Data
