 Hello Daniel,

 I'll admit that I've never tested ALLWINNER kernel without INVARIANTS
or WITNESS recently, I'll try that.
 I assume that you've patched your DTS for ethernet support, can you
try with the unpatched one ?
 It seems that it panic because the mod0 clk doesn't have the correct
parent.

 For the semi random MAC address this is expected. The awg driver
generate a random one if it can't use the SID root key as
the "source", which we don't support for now on H3 (it shouldn't be 
hard to add support for the H3).

 Cheers,
