Ubuntu 11.04(with kernel 3.4.4) boot error "VFS: Unable to mount root fs on unknown-block(0,0)"

I just upgraded my kernel version from 2.6 to 3.4.4(from kernel.org) and built the kernel using the following commands:

Code:
make
make modules
make modules_install
make install

update-initramfs -c -k 3.4.4

Then I checked the grub.cfg and it showed me an entry for 3.4.4.


But the kernel is not booting and I get the vfs error:

Code:
VFS: Cannot Open root device "sda1" or unknown-block(0,0)
.
.
.
VFS: Unable to mount root fs on unknown-block(0,0)
.
.
.
Call Trace:
.
.
.

How to resolve this issue?

i don't think the generic kernel will run with ubuntu... why not using "apt-get" to update your system?

Thanks duke for the reply.
I had been using the kernel 2.6 earlier and it was running fine.
