Subject: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(2,0)
Date: Sun, 11 Dec 2005 15:30:12 -0300
Hi all,

I've just installed Gentoo 2005.1-r1 on my amd64 box and i've got this 
problem while rebooting:

Root-NFS: No NFS server available giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy and press ENTER
end-request: I/O error, dev fd0, sector 0
VFS: Cannot open root device hda2 or unknown-block(2,0)
Please append a correct "root=" boot option.
Kerenel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(2,0)


What should i do? is it a grub configuration problem? or kernel compilation?

Here is my grub.conf

#
# Sample boot menu configuration file
#

# Boot automatically after 30 secs.
timeout 10

# By default, boot the first entry.
default 1 #SECOND

# Fallback to the second entry.
fallback 1

#splashimage=(hd0,1)/grub/splash.xpm.gz
#GENTOO
title  Gentoo Linux
root (hd0,1)
kernel /boot/bzImage-2.6.14 root=/dev/hda2
#initrd /initrd.img

# For booting Windows NT or Windows95
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader  +1
# For loading DOS if Windows NT is installed
# chainload /bootsect.dos

root (hd0,1)
setup (hd0)





Thanks in advance,

Felipe
