So I did some backtracking and through playing with this thing I found something I want yalls opinion on. After I used the "Genkernel All" command, I was told to check the created kernel image name and initrd for later reference when configuring the boot loader. (Grub in this case)

Here's the results:

Code:

ls /boot/kernel* /boot/initramfs*
ls&#58; /boot/initramfs*&#58; No such file or directory
/boot/kernel-genkernel-x86-2.6.12-gentoo-r6

So here's my question of course, what's the initramfs/initrd and why is it saying no such file or directory.

Thanks

initrd = initial ramdisk

It may say that it doesn't exist because you don't have one... Not all setups use initrd, I don't use it. Did you check your fstab setup aswell?

Okay, I brought up the Fstab. This was a long process copying by hand, but here it is.

Code:

/dev/boot                     /boot           ext2       noauto,noatime       1 2
/dev/root                     /               ext3       noatime              0 1
/dev/swap                     none            swap       sw                   0 0
/dev/cdroms/cdrom0            /mnt/cdrom      iso9660    noauto,ro            0 0
#/dev/fd0                     /mnt/floppy     auto       noauto               0 0

Note&#58; next line is critical to boot.
proc                          /proc           proc       defaults             0 0


shm                           /dev/shm        tmpfs      nodev,nosuid,noexec  0 0
/dev/hda1                     /boot           ext2       defaults,noatime     1 2
/dev/hda2                     none            swap       sw                   0 0
/dev/hda3                     /               ext3       noatime              0 1
none                          /proc           proc       defaults             0 0
none                          /dev/shm        tmpfs      nodev,nosuid,noexec  0 0
/dev/cdroms/cdrom0            /mnt/cdrom      auto       noauto,user          0 0

Whew, Well there it is. Getting the thing to format all pretty in this post was a lot of work.
Let me know what you think.

That's easy: just write the mono-space stuff in a monospace text editor and then cut-n-paste to the reply box!

I think the lines for "/dev/boot" and "/dev/root" and /dev/swap" are just for example. I think you should delete them or comment them out with a '#' at the beginning of the line. Your "/dev/boot" is apparently "/dev/hda1". Also, I think proc should be last. So, not counting commented lines, I think this should be your fstab:

Code:

shm                           /dev/shm        tmpfs      nodev,nosuid,noexec  0 0
/dev/hda1                     /boot           ext2       defaults,noatime     1 2
/dev/hda2                     none            swap       sw                   0 0
/dev/hda3                     /               ext3       noatime              0 1
none                          /proc           proc       defaults             0 0
none                          /dev/shm        tmpfs      nodev,nosuid,noexec  0 0
/dev/cdroms/cdrom0            /mnt/cdrom      auto       noauto,user          0 0
proc                          /proc           proc       defaults             0 0

Maybe someone else can second this?

Almost, drakebasher you have double lines for proc and shm! Also, in this example I add an entry at the bottom for usb pendrive and floppy disk, remove the "#" in front of them if you need them:

Code:

/dev/hda1                     /boot           ext2       defaults,noatime     1 2
/dev/hda2                     none            swap       sw                   0 0
/dev/hda3                     /                   ext3       noatime              0 1

none                            /proc              proc       defaults             0 0
none                            /dev/shm        tmpfs      nodev,nosuid,noexec  0 0

/dev/cdroms/cdrom0    /mnt/cdrom      auto       noauto,user          0 0
# /dev/fd0                    /mnt/floppy     auto       noauto,user               0 0
# /dev/sda                    /mnt/usb         vfat       noauto,user               0 0

So I changed my fstab to match the recommendations. I went back through and re-wrote the grub.conf as well. Luckily It goes straight through for the most part, in other words no more hanging and making me type the whole:

Code:

kernel /kernel-genkernel-x86..... &#40;etc, etc&#41;

But here are the remaining issues, first off it goes to a blank screen with a blinking cursor in the upper left hand corner. It waits there until any key is pressed and then completes the boot loader and into the kernel loading phase. Also the text is displayed in a very strange way, it appears garbled and trashy looking as it executes the boot loader phase prior to the kernel phase. Not that this is really an issue to fret over, but if it's a quick fix, by all means let me know...

And secondly, most importantly, I'm still getting the Kernel Panic - not syncing. Any ideas? I have the fstab completely blank, and wrote ONLY what was posted by jaboua. What else causes this "mis-syncing"?
Would it have something to do with the fact that it's checking root block (1,0) and not (0,0)? Just a stab in the dark, I'm trying to think of reasons for the failure here.

**Sovtek** · 09-26-2005

I just thought I should be sure and describe the exact error I was getting, once again, just for the sake of clarity and reference.

Code:

&#40;more stuff prior&#41;
Net&#58; Registered protocol family 1
Net&#58; Registered protocol family 17
UDF-fs&#58; No Partition found &#40;1&#41;
XFS&#58; bad magic number
XFS&#58; SB validate failed
Kernel panic - not syncing&#58; VFS&#58; Unable to mount root fs on unknown_block &#40;1,0&#41;

And this is a Stage3 install of Gentoo Linux, version 2.6.12-r6, x86, and 'genkernel all' was used. The system is using the 2005.1 x86 handbook as the default settings. Also, the partitioning scheme is:
/dev/hda1 ext2 appx 32Mb (Boot)
/dev/hda2 (swap) appx 512Mb (Swap)
/dev/hda3 ext3 rest of the 20Gb (Root)

Would any other info be of service with this issue?
Thanks.

Can you post the grub config as well?

**Sovtek** · 09-28-2005

Here's my Grub.conf

Code:

default 0

timeout 30

splashimage=&#40;hd0,0&#41;/grub/splash.xpm.gz

title= Gentoo

root&#40;hd0,0&#41;

kernel /boot/kernel-genkernel-x86-2.6.12-gentoo-r6 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda1

Anything out of place?

**jaboua** · 09-28-2005

Try adding a space between "root" and "(hd0,0)"
