G2 Mini D620 kernel compilation problem - LG G2 Mini

Hello, I'm trying to compile my own kernel from sources for this piece of hardware, everything went well and I completed the whole process, but with my kernel device doesn't boot up and stuck on boot screen at bootloader stage (fastboot mode). I'm using CNexus Boot.img tools from here. To obtain
PAGE SIZE: 2048
BASE ADDRESS: 0x00000000
RAMDISK ADDRESS: 0x01000000
I've used arm-eabi-4.6, stock and working kernel with command ./boot_info boot_327680.bin so I think, these parameters are ok.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Whole ramdisk image is also taken from stock kernel with command ./split_boot boot_327680.bin. Configuration used ".config" comes from stock kernel too. Even after compilation of pure split image, device won't boot...
This piece of code I'm using to compile kernel image for example:
Code:
./mkbootimg --kernel boot_327680.bin-kernel --ramdisk boot_327680.bin-ramdisk.cpio.gz --cmdline "console=ttyHSL0,115200,n8 androidboot.console=ttyHSL0 user_debug=31 msm_rtb.filter=0x37 androidboot.hardware=g2m" --base 0x00000000 --pagesize 2048 --ramdiskaddr 0x01000000 -o test_stock.img
It looks like in newly compiled kernel at the end of file a lot of code is missing.
You may open following files with hex or text editor to see what I mean.
Stock kernel:

Compiled one:

Any suggestions?

Thank you for that, didn't really know about that, now I have to find out how to build dt.img or extract it from stock image.

I managed to build working kernel but something is still wrong with graphics, there is no image, display stays black. I can hear that system boots up and touch is working, adb is working too.
EDIT: Attached here kernel with broken video and logcat of it.
If someone want to test it and help me to find out the problem, do nandroid boot backup first!

Guys for CM we need CAF kernel. Kernel from me is CAF and need couple of fix but system is boot and working.

And are you using stock ROM?

Yes, stock odexed ROM.
PS. Repacked with this method and then compiled stock boot.img is working ok, so I assume something is wrong with zImage instead of ramdisk.

If you upload the source that you used to GitHub I vould help you more, because I doubt that you used stock kernel source code plus stock defconfig, as in logcat appears some errors of missing functions that are defined in stock kernel source

Here you go, kernel compiled from clean LG sources + Garcia98 config file cyanogenmod_g2m_defconfig. Still working system with black screen
