I have been compiling my own kernels since I got my board. All of the 4.14 revisions have worked great.
4.15-rc1 works fine, but only after it finally gets ethernet initialized. It seems to take about 5 minutes or so for the network to come up during which time I am not seeing any diagnostics to let me know what is happening.
Has anyone else tried a 4.15 kernel and if so are you getting similar results.
