i don´t know what machines you cansider "old" but a full
kernel-compilation on a 486 with 20Megs RAM takes about an hour...
whatever "make dep" is for, it is *not* for partial recompilation, make
recognizes *automatically* which parts have to be recompiled after a
Do you always "make clean" before compiling your kernel??
