Hi Christian,

Unfortunately there is no source code in that commit, it's just a merge. And
your bisect run found that the very first commit in that merge was OK:

So I'm not convinced your bisect run was correct, sorry.

My pasemi is booting OK, but I haven't had time to test the network. If you
remind me next week I will make sure network is working on my board.

Are you testing your board with your additional patch as well? Or just vanilla
mainline?

cheers
