The problem stems from this patch: https://lkml.org/lkml/2014/7/8/579
It introduced two dts with the same machine name. I have submitted Kernel patch [PATCH 1/1] imx6q-wandboard-revb1.dts: use unique machine name https://lkml.org/lkml/2016/2/6/58 When upstream accepts the patch, please, consider to add it to Debian. Together with an update of file all.db in package flash-image this should fix the problem. Best regards Heinrich Schuchardt
