I think your kernel is crashed or boot cannot find where the kernel locates but it is too broad to say why it is stopped until actually have a look at it carefully with many possibilities.
If you haven't modified kernel, then it may have a problem with partition or SD card itself.
If you are just aiming to boot OS, I suggest you simply use "NOOBS" to boot what Raspberry supports
Below is my booting log and I don't think your kernel didn't actually started.
