After upgrading the kernel,I restart the computer.When I choose the new kernel vision,I met a problem below:
kernel panic -not syncing:vfs:unable to mount root fs on unknown block(0,0)

But I enter the old kernel successfully,I don't know what's wrong with the new kernel.Any help will be appreciated.

Here is my /etc/grub.conf:

splashimage=(hd0,2)/grub/splash.xpm.gz
