Re: The kernel halt after "transferring control to linux(0x000000)..." on HD860(MPC860SR) board kernel 2.4.25, and 2.6.12

In message [off-list ref] you wrote:

  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.

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

  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() 

Locate the problems and fix them.

 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

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

Best regards,

Hope you are connecting with right port speed.
