OK, so this really hints at a regression in the mvneta driver itself. Could you try to revert just: 6ad20165d376fa07919a70e4f43dfae564601829 a29b6235560a1ed10c8e1a73bfc616a66b802b90 2a90f7e1d5d04e4f1060268e0b55a2c702bbd67a first all of them, and then each one by one, so that we can pin-point the commit that causes the breakage ? I looked at all the other changes in mvneta between 4.10 and 4.12, and I don't see how any of the other changes can cause a functional difference. So let's focus on those 3 commits for the moment. Assuming you're using Git, to revert a commit just do: "git revert ". Thanks again! Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
