Hi Looper

Like :
Code: [Select]
kernel_total_size
Code: [Select]
loading /boot/core.gz
Code: [Select]
loading /boot/vmlinuz
Those messages sound like they are from the boot loader.

That one sounds like it might be coming from the kernel. You could try silencing it with the following boot code:
Code: [Select]
loglevel=0
Which boot loader are you using?

Code: [Select]

Hi Looper
Posting the contents of your config file might also be helpful.

Many tanks again for your replaying @Rich

This is my isolinux.cfg
Code: [Select]
default mc
Label mc
      Kernel /boot/vmlinuz
      Append initrd=/boot/core.gz loglevel=0
Console 0
Implicit 0
Prompt 0
Timeout 0

Notice : I changed with your reply
But for now with this configuration I got :
Code: [Select]
early console in extract_kernel
Input_data
Input_len
Output
output_len
Kernel_total_size
Decompressing Linux
Booting the kernel

Append initrd=/boot/core.gz quiet loglevel=0
