>Description:
Here is a sample from dmesg before my change:
CPU: Unknown 80686 (451.03-MHz 686-class CPU)
and after :
CPU: Pentium II Celeron (Mendocino) (451.03-MHz 686-class CPU)
>How-To-Repeat:
Boot the machine with an Intel Celeron or Celeron (Mendocino)
Processor, and you get Unknown 80686 cpu.
