Dear Gala:
  I meet a problem when porting kernel  2.4.25,and 2.6.12 to a HD860 board: Whatever your config, or whatever you patch, set ppcboot enviroment, 
  whether use ramdisk or nfs, the kernel  all display a message then halt.
  "transferring control to linux (0x000000) ..."
  The log_buf in Memory display that the kernel has problem at : 

  1. /init/main.c  calibrate_delay() ;
  2. /init/main.c  do_initcalls() do while dead loop!! 
  3. /init/do_mounts.c mount_root() 
 
 Does it need any patches? thanks!
 The kernel 2.4.25 is from ELDK 3.1.1, 2.6.12.3 is from kernel.org

Where are "transferring control to linux (0x000000) ..." ?
If are you use in The kernel 2.4.25 is from ELDK 3.1.1?
Please check you uboot.

How do you define "halt"? There is no "halt" instruction in the  CPU,
so it must be doing "something".

Locate the problems and fix them.

this kernel works fine on many, many  other  boards.  It's  extremely
likely that the problems are caused by your port only.

Hope you are connecting with right port speed.
