[Buildroot] about buildroot init

[黄庆]

hi,
  I use buildroot for ixp425 & MPC8280,I get some troubles.
  I make rootfs.powerpc.ext2.gz,and use it for ixp425 & mpc8280 ramdisk.
  When linux uncompress ramdisk.gz,exec init,then system halt

if del /sbin/init ,then I can direct enter bash ,so I think that is init's promble.

Then system is halt!

my environment
1) MPC8280 & IXP425  hardware is OK
2)if mpc8280 use MontaVista's rootfs ,it work OK,and if ixp425 use snapgear build ramdisk.gz ,It work ok,too.
3)buildroot version is 2006-8-17 snapshot,gcc is 4.0.3,linux-kernel include 2.4.31,binutils 2.16.1,uClibc & busybox is snapshot 2006-08-17
4)mpc8280 zImage: linux kernel version is 2.4.26 ,IXP425 zImage:linux kernel version 2.4.27

  so please guide me how to resolve this issue

Thanks
