[gentoo-user] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(2,0)

[Felipe Ribeiro]

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

kernel -- make sure / fs support is _not_ modular, for
starters

I've removed Windows from the grub.conf file, just to test, and now
when i try to start linux, it reboots the system instead of showing
the message: "Kernel panic - not syncing: VFS: Unable to mount root fs
on unknown-block(0,0)

This usually means you did not compile the driver for your root
filesystem into the kernel.  Maybe you compiled this as a module?

I don't think these setup lines should be in grub.conf.  I'm not sure
that it causes any harm, but it doesn't look right to me.

Whatev. The kernel has to be able to read it without
having to wait for a module.
