Thank you.
I have managed to compile the kernel (got some suggestions from the guys at sailfishos-porters) then I built two sailfishos image. None of them boots. The phone stuck at the Samsung logo. And none of them gets mac address/ip address either. So telnet doesn't work, I need to manually assign a mac address and bring up the network to be able to telnet in to the phone. Then, I can start journal and see messages but mostly look ok, so I am puzzled why it doesn't continue the init process.

Edit: probably the selinux is not disabled and that is the problem.
