Actually, /usr/src/linux is pretty much deprecated by the Prime Penguin himself; you're supposed to keep your kernel sources somewhere else. I got lazy and used it in the example, mostly because it's shorter to type than the /lib/modules path. The latter is the better way to go, however, especially in scripts or makefiles - it "automatically" points to the right source tree, unless you move your trees around.

Hi rashminivarthy,

your kernel is not module enabled,
obviously.

Sincere Regards,
