Is wrong my kernel command line, on this situation ? (Booting L4 linux)

[Taeung]

Hello, every l4-hacker.

I've succeeded booting "Hello world + L4/Fiasco" on Freescale 
i.MX6q_sabre_sd because big help of Admed, Tim, Matthias.

And then, I'm trying to boot "L4 Linux + L4/Fiasco" on my board.

I've  configured for L4 linux build.
Such as..

|System type -> ARM system type (L4 Linux)
Build type (Use ARMv7)
|

And then, I've successfully build it.

I've did "make uimage E='L4Linux ARM' ..." ,so I've got uimage.
And I try to boot it ,using 'uImage' and 'u-boot.bin'.

But I did not boot it on my board.
It was stoped at "l4linux | panic: going to sleep forever, bye"

====================

I guess that the problem is somthing about ramdisk(root file system) and 
kernel command line might be wrong.

Referentially I've used ramdisk file(ramdisk-arm.rd) and my kernel 
command line
"setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 
rootwait rw video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 
video=mxcfb0:dev=hdmi,1920x1080M at 60,if=RGB24'".

How do you think about that?

Is wrong my kernel command line,on this situation ?
