I just compiled and installed a 2.6 kernel but I just can't seem to get it to boot.


The root file system is stored in one file called rootfs. The 2.4 kernel still loads everything just fine but when I boot up the 2.6 kernel I get this:
Code:

>> Activating mdev
>> Determining root device...
!! Could not find the root block device in .
    Please specify another value or: press Enter for the same, type "shell" for a shell, or "q" to skip...
root block deivce() ::


Here is my linuxboot.cfg file for my bootloader:
Code:

title Gentoox
kernel vmlinuz
initrd initrd.gz
append init=/linuxrc installtype=e-drive root=/dev/ram0 kbd-reset video=xbox:640x480,nohwcursor,hoc=13,voc=13

title Sparkle
kernel vmlinuz
initrd sprkrd.gz
append load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=26215 rw root=/dev/ram kbd-reset

title Gentoox-2.6
kernel vmlinuz-2.6
initrd initrd-2.6
append init=/linuxrc installtype=e-drive root=/dev/ram0 kbd-reset video=xbox:640x480,nohwcursor,hoc=13,voc=13


Here is my /etc/fstab file:
Code:

# /etc/fstab: static file system information.
#
# <file system>         <mount point>   <type>          <options>              $
/dev/loop/0             /               reiserfs        notail                 $
proc                    /proc           proc            defaults               $
/dev/cdrom              /mnt/cdrom      iso9660         defaults,ro,user,noauto$
/dev/hda51              /mnt/fatx/c     fatx            defaults,noauto,umask=0$
/dev/hda50              /mnt/fatx/e     fatx            defaults,umask=0000    $
/dev/hda55              /mnt/fatx/f     fatx            defaults,umask=0000    $


Now I have built reiserfs filesystem support into the kernel but that is the only solution I could really think would work but the error still shows. Does anyone know what could be wrong?

Thanks,

It's either one of two things:
1. You don't have the ReiserFS support in your kernel.
2. You don't have support for your IDE/EIDE/ATA/SATA (or whatever you have) interface in your kernel.

In your case I think it'll be the second option, as the first one would probably return another type of message. Check your hard drive interface drivers in the kernel (for the time being most probably ATA or SATA drivers).

EDIT: Hold on a minute. Which partition is used for what and what bootloader do you use?

looks like your using an xbox so make sure your using xbox-sources rather than gentoo-sources. Also make sure you have xbox specific options enabled (ive never used xbox-sources so ive no idea what if any extra options there are), however id guess that theres some extra fat options as the xbox uses a modified version of fat as its filesystem iirc. Also id look at things like ramdisk support.
