I really don't know.. I don't have stock kernel to test on, I have the generic boot.img of 4.4 image, so it isn't fixed, because this build is from february, and it wasn't fixed. Don't know how to help you, but the OTG doesn't act with your kernel.
OTG works, but you need a 3rd party app to use it. There's NOTHING I can do on the kernel side since my kernel has the same log as your fake "stock" kernel. so from kernel's perspective, there's nothing wrong.
