After some of the recent ‘Ethernet fix’ patches have not worked with more recent linux-next kernels, I have found one that – at least at the moment – does fix the ‘hang’ problem – again..

The patch is applied to meson-gxbb-odroidc2.dts, and can be found here:  http://archive.arm.linux.org.uk/lurker/message/20161221.113134.3ac4d1e6.en.html

I did have to revert this kasir_offset patch (…-R) to stop the linux-next (December 22) kernel compile from failing:  http://archive.arm.linux.org.uk/lurker/message/20161211.005055.ad5e5693.en.html but hopefully this will be fixed in a later version..

With this dts patch, I now have a stable Ethernet connection on the C2 – again..

I should mention that this only gives a headless boot, as USB/Graphics still do not work, on my C2..
