Hi all,

After booting successfully the kernel without a root file system.

I  installed a file system on the flash disk. I used: BusyBox 1.12.1, and
the script mkrootfs.sh (written by 

Wofgang Klingauf) to generate the rfs.

I changed the boot arg in the kernel configuration as follows:

 [*] Default bootloader kernel arguments                                                                    
│ │ 
  │ │                                      (console=ttyUL0,9600
root=/dev/xsysace/disc0/xsa3 rw) Initial kernel command string 

Then I rebooted the kernel, and there were those errors :( :

Linux/PowerPC load: console=ttyUL0,9600 root=/dev/xsysace/disc0/part3 ip=on
