Unhappy [Q]Xperia Miro - Vengeance kernel - Start dumping ram to sd card

This is my device

Xperia Miro st23i
Paradox V1 ROM from here : http://forum.xda-developers.com/xper...radox-t2209026
Stock kernel

So i want to flash kernel to vengeance
Flashing process is OK, no bad blocks or error, but when i reboot it won't boot to home screen. The sony logo appeared and then reboot again by itself and then display the "start dumping ram to sd card" then reboot and dumping again repeatedly until it tell me that the sd card is full. So i fix this by flashing the kernel to stock again and there is a "ramdump" folder in my external sd with HUGE size.

I also try other vengeance kernel. Here are some kernel i tried and the result
vengeance v 1.46 : stuck in sony logo and cant boot
vengeance v 1.40 : ramdump problem above
vengeance reloaded (with gpu oc) by shivang dave : ramdump problem
vengeance (i dont know which version) the one included in UltraBeast Rom by shivan dave : ramdump problem

i heard some people can successfully flash their miro with vengeance v 1.40

Is anyone can help solve this problem?
