I have just compiled a kernel for my work station and it vent quite well due to god advices from laurentbon:
The last problem to solve is the cash memory size that is reported to be 32 kb when doing a 'more /proc/cpuinfo' , it should be 512 kb.
The machine is equipped with dual Intel Tualatin processors.
At the kernel configuration the processor type was selected to be Intel P3.
Some one have an idea how to solve?
