Have you rebooted after updating the kernel ?
I don't think so.
You are running 4.9.41-v7 kernel while 1.20171029-1 is 4.9.59

Thanks, that was it, didn't make the 20171029-1 -> 4.9.59 connection when looking at apt list as the 4.9.59 reversion number is not part of the package name. Sorry for the noise.
