ok compiling kernel 2.6 using the defult setting but add ntfs read support and changed the processors type to P4

i do these command:
1) # make xconfig
2) # make bzImage
3) # make modules
# make modules_install
4) # make install

1) make xconfig:
all went fine i added ntfs support (as a module)
i also changed the processors type to Pentium 4
others using default settings.

2) make bzImage:
all went fine and no error

3) make modules and make modules_install: i got the warning/error message as below
