VFS: Cannot open root device

[c4rdinal]

Hi,

I'm having problem compiling the new kernel linux-2.6.17.8.
Error appears on boot-up:

VFS: Cannot open root device "<<NULL>>" or unknow-block (8,8)
Please append a correct "root=" boot option
Kernel Pannic - not syncing VFS : Cannot open root device or unknow-block (8,8)

And my grub looks like this:

/etc/grub.conf

title Fedora Core 5-new
root (hd0,0)
kernel /linux-2.6.17.8

#lspci

00:0f.1 IDE interface: VIA Technologies, Inc.
VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)


I understand that the error shows that my IDE controller was not installed in
the Kernel config. I selected in the make menuconfig:

DEVICE DRIVERS --> ATA/ATAPI/MFM/RLL --> VIA82CXXX

But the same error occur while rebooting the kernel. What should be enabled in
the kernel to fix the problem? Any suggestions?

I'am building Monolithic Kernel.

Thanks,

It's telling you that you had not specified a root device in your grub config.

default=0
timeout=5
password --md5 $1$WKmXM1$oCg.S/hgVGAFQ5tdhTmQE0

Add the root partition to your kernel line in grub
