The CuBox-i4 Pro booted Kernel 4.0-rc1 OK, but – although eth0<\/em> was present – there was no network connection possible..<\/p>\n

I found a similar problem described on the Linux Arm Kernel mailing list:\u00a0 http:\/\/lists.infradead.org\/pipermail\/linux-arm-kernel\/2015-February\/325249.html<\/a><\/p>\n

According to the info there, I changed linux\/arch\/arm\/mach-imx\/mach-imx6q.c<\/strong> as follows:<\/p>\n
