How to fix ubuntu 12.10 can't start with kernel 3.15?

hi all:

I get the kernel in branch:

git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
And I config and make it by:

make localmodconfig
make
make modules_install
make install

when these have done, I reboot the computer. I can see kernel 3.15 in grub list. When I start with it, the screen is:

Loading Linux 3.15.0-rc5+ ...
Loading initial ramdisk ...

then the screen stopped. So How can fix it?
I can't find any useful error messages because the computer don't get into the kernel.
Thank you.

Did you type make modules ? It's sounding as module issue.

You'll have a much easier life if you stick with the way your distribution builds and installs a new kernel:
