I can build v18.06.0-rc1 just fine, and it boots on my WNDR3700v3. But the latest snapshot - it builds fine, and installs ... but the boot fails as follows (just hangs at the last line below). Anyone else seeing this?

Don't worry about the MAC or that it says WNDR4000 - the initial OpenWrt flash trashed this info - but the other build (18.06.0-rc1) is just fine with this.
