Hi all I just switched to kernel 2.4.22 and i got an error saying that "somthing is wrong" about /usr/src/linux/include/asm/errno.h . What there is no /usr/src/linux/include/asm folder into the kernel sources , but there are "/usr/src/linux/include/asm-*" folders ( have a look yourselves ) so i just made a symlink : /usr/src/linux/include/asm that point on my archtecture and then it works . Thanks .
