boot problems after compiling kernel 2.6.6

[Buller]

hi all.

i'm trying to run debian with kernel 2.6.6.
i installed debian with the sarge iso and downloaded the kernel-source-2.6.6 afterwards. i ran through the menuconf and checked support for my hardware configuration. everything seemed to go okay, but when i rebooted i got:

VFS: cannot open root device "hda1" or unknown-block(0,0)
please append a correct "root=" boot option
kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)

any help would be very much appreciated!
oh my hardware specs are:
asus k8v se
AMD Athlon 64 3400+
1024 mb samsung ram.
Nvidia GeForce fx5600
IBM 60 gb hd

if i forgot anything or if more nfo is required please lemme know. I'm a half-noob 2 linux so please answer in a not too much technical way. Thanks a lot.

All the problems with your VIA Technologies are SATA problems, as i've done some good research. I'll check out some more sites.

P.S: I was helping Buller on IRC and i couldn't get any more info, so I suggested he try our Forums.

It looks as if you did not specify what the root partition is in your boot loader configurations. If you are running LILO, you need something like root = /dev/hd<letter><number> below the image = /path/to/kernel_image. As for GRUB, check this: link

hello,
are you using GRUB or LILO? I am guessing that there is an issue withthe mapping - for GRUB you need to edit /boot/grub/grub/conf and /boot/grub/device.map - here are mine as examples:

grub.conf

# grub.conf generated by anaconda
#kernel /boot/vmlinuz-2.6.5-1.358 ro root=/dev/hdc2 rhgb quiet
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd1,1)
#          kernel /boot/vmlinuz-version ro root=/dev/hdc2
#          initrd /boot/initrd-version.img
#boot=/dev/hda
default=1
timeout=10
splashimage=(hd1,1)/boot/grub/splash.xpm.gz
title Fedora Core (2.6.5-1.358)
        root (hd1,1)
        kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/1 rhgb quiet PCI=noacpi 
noapic nolapic
        initrd /boot/initrd-2.6.5-1.358.img

title Kernel 2.6.6
        root (hd1,1)
        kernel /boot/vmlinuz-2.6.6 ro root=/dev/hdc2 
        initrd /boot/initrd-2.6.6.img

title Kernel 2.6.7
        root (hd1,1)
        kernel /boot/vmlinuz-2.6.7 ro root=/dev/hdc2 
        initrd /boot/initrd-2.6.7.img

title Linux 2.4.22
        root (hd2,0)
        kernel /boot/vmlinuz-2.4.22 ro root=/dev/hde1 idebus=ata66 hdh=ide-scsi
        initrd /boot/initrd-2.4.22.img

[root@bugs ~]cat /boot/grub/device.map 
# this device map was generated by anaconda

if you are not using grub please let us know.

I downloaded the knoppix conf for the 2.6 kernel and now it all works fine... but it's a shame it loads many things i don't even need. i guess i screwed up when i compiled the kernel my self... sorry for being noobish guys thanks a lot for your help, u have all been great!

Glad you got it working. In case you're wondering what was wrong, you can always look at the Knoppix 2.6 kernel's config and possibly compare with your kernel config and next time, you won't need a Knoppix Kernel.

Thats a good idea! i might do that tomorrow. and of course let you guys know where i screwed up. hehe

cheers
