Just for the record: loading i2c-mv64xx.ko reproducibly hangs my Debian
Jessie install with the 4.3.0-0.bpo.1-armmp-lpae kernel.
This happens only on u-boot 2016.01; both Debian stable 2014.10 and my
own build of 2016.03 + patches work fine!


So no problem since it's fixed on newer builds.
Just a note for those playing along at home and wondering why their
olinuxino does not come up anymore with 2016.01.
