Hi Fabio I've never used bisect before and I have thusfar failed to get ARM cross-compilation to work so I'm a bit wary of having to spend several days rebuilding Linux several times on my board.
I think the first thing I need to do is to see what other archived Arch kernel packages I can get - hopefully I can find packages for 4.9.1, 4.9.2 etc. I would imagine that if I can find the stable release post 4.9.0 where imx6 SATA speed took a nosedive, that will make bisecting much faster. If anyone has an easy to follow, known working guide to setting up cross-compilation from amd64 -> armv7h, that would be massively helpful as none of the ones I have tried in the past have worked.
