Hello everyone,
I have received the response from Lee, one of the export in Android
porting.
Thanks Lee's suggestions.
I post his response in here, and wish to help your porting job.

Lee said~
In my opinion, your problem is LCD flickering.(framebuffer driver)
Your android system is not died.
It just tries to display something. (but CPU usage 99%, trying
EGLDisplaySurface().. )

To solve this problem,
Modify your framebuffer driver.

Brief Overview :
1. double buffering ( yres * 2, and memsize * 2)
2. provide *_pan_display() function (android init check this by ioctl
loop)

You have to run the init in the android file system, this starts the
various services that will follow. You can boot into the shell and
then issue it manually too.
