happends on 2.4.20 dont happend on  2.4.17 , and now im using that kernel
and it works awesome.-
i know thath is not an correctly solution ok ?
but IT works Correctly .- Why ? really dont know , if U can givme an ftp or
something  i have a 2.4.17 already patched i can upload it to You.-


p/d : I know thats is not a right way , but i U need a solution now , that
help i can give U , as I say U before , i have a 2.4.20 kernel working , but
when i try to make the same compilation in another machine , i don't know
waths go wrong... and invalid arguments apears.....
