I've posted a mail with the screenshot (waiting for moderation) when I try to boot from make defconfig built kernel. Basically the kernel doesn't boot because "Missing modules (cat /proc/modules; ls /dev " it says...It's the same screen that appeared when I tried using make oldconfig pressing enter for default values.
I tried using make localmodconfig but It again asks for many config params that I don't know anything about.Saludos,
Abel.

Hi.I just built using make defconfig and it, again, doesn't boot. Instead it displays the error that I've described before (sorry I forgot to attach the screenshot, I attach it here).
As I already stated, neither /boot/${uname -r} nor make oldconfig work for me, they both show the screen above.

To add to what Ozgur said, you may first copy the existing .config
file that comes along with your Linux distribution to your kernel
tree, and then use:
$ make localmodconfig
instead of defconfig. A quick Google search should tell you the
differences between the two - and from what I've read, localmodconfig
is preferred to defconfig.
Hope this helps.
