I have downloaded the source of linux kernel 2.6 and built it with the default configuration. I am testing it on qemu-system-x86_64 with the following command :-
qemu-system-x86_64 -m 1024 -smp 4 -kernel arch/x86/boot/bzImage -initrd initramfs.gz -append "rdinit=/ root=/dev/ram" -serial stdio -append "root=/dev/ram0 console=ttyAMA0 console=ttyS0"
and, it is showing the following error when it tries to boot :-
end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
with the stack trace being the following :-
9.187305] Call Trace:

I have been searching more about this error but, am not able to identify the cause of this error. Can anybody please explain it to me why am I getting this error ? How can I resolve it ?
Please bear in mind that I have just started kernel development and still a noob in this area.
