you are clearly using ubuntu, so here's a simpler recipe i've used
successfully.
1) configure and build your kernel from the source
2) "sudo make modules_install"
3) "sudo make install"
4) "sudo update-initramfs -c -k <kernel version goes here>"
5) "sudo update-grub"
the drawback to the above is that your kernel is not built as an
official *package* but for testing purposes, it should do. you'll get
your kernel installed under /boot, your modules installed, a new
initramfs image, and your grub file updated. can you try it this way
and see if it makes a difference?
