Thanks for your suggestion! I tried and it seems the previous 
problem disappeared but it throws out another  error:

"Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "sda5" or unknown-block(2,0)
Please append ac correct "root=" boot option; here are the
available partitions:
Kernel panic - not syncing: VFS: unable to mount root fs on
unknown-block(2,0)
Pid: 1, comm: swapper Not tainted 2.6.31-gentoo-r10 #2"

I searched the Internet for a while, but still can't find any solutions.
The root partition is definitely sda5, as also specified in the fstab file.
