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

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

[Rafael Fernández López]

Hi,

I've googled and I haven't got any successfull results. I've my hard disk
as follows:

/dev/hda1 - ext2 (here will go /boot)
/dev/hda2 - swap
/dev/hda3 - ext3 (here will go /)

I've compiled gentoo-sources with NO genkernel, but manually. I've no
filesystem as modules, everything is included in kernel (as asterisk (*)).

I am getting the next error when booting:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown
block(0,0)

And my bootloader is grub, here is grub.conf:

default 0
hiddenmenu
timeout 5

title=Gentoo GNU/Linux
root (hd0,0)
kernel /vmlinuz-2.6.17-gentoo-r5 root=/dev/hda3

I can't figure out what's going wrong... because I think that I don't need
initram because I've nothing compiled as a module.

Thank you very much,
Rafael Fernández López.

Rafael,
Did you compile in support for your IDE "controller"?

Well, I think so... is not a SCSI drive or similar. It is just an IDE hard
drive, no special support is required.

Anyway it doesn't matter I've re-formatted with:

/dev/hda1 ext3 (here will go /)
/dev/hda1 swap

As I have my others computers.

Thank you,
Rafael Fernández López.

What ever file system you use for /boot and for / must be included IN
the kernel, not as modules.  It has to be able to read it for it to load
the modules.

That should help.

I guess I misread it then.  It is common for someone to not put the file
system root uses in the kernel though.  Me, I don't use modules at all. 
The only module I have is nvidia.
