Build: OpenWrt SNAPSHOT r13600-9a477b833a / LuCI Master git-20.168.54087-84a0b68

Similar crash, but this is using the snapshot from OpenWRT. Pretty much identical to hnyman's build. Unfortunately it looks like it is coming from the closed binaries if I'm reading it right. It basically stalls/locks up.

The curious item - it worked, somewhat, for another 24 hours before the wireless went completely down.

Reboot brought back wireless.
