GRUB Error 15 for -21 Kernel.

[ShinobiTeno]

Hello!!=)

This week I got the kernel update to -21 appear under Updates and performed it. It went flawlessly, and added -21 to menu.lst, but the problem is: every time I try boot into it(by selecting it in GRUB menu,its marked as default), I get Error15: File not found. -19 boots no problem!
Menu.lst is ok, i checked it three times. File locations(/boot, and symlinks in /) are ok. I force reinstalled -21 kernel as well. No change. I suspect that 1024 cylinder makes it happen... I suspect that the new kernel got behind 8Gb and GRUB cannot access it... Does we have to do a separate /boot partition right on the start of the disk? Any ideas it happenz?


Additional info:
Ubuntu Studio(Hardy), GNOME.

2x500GB(WD5000AAKS) sata on sil3152. One work, one 1:1 backup. One old PATA disk, with very known OS, that is going to be dd`ed very soon, for it looks quite useless contra linux)

System is set to boot from SATA, hd0(GRUB) is sdb. Because of libata mixing Pata and Sata, it gets placed second, behind old Pata drive.

Partiton Map for 500Gb disks(sdb,sdc) is the following
<sdb1="/"> <sdb2 <sdb5="~/DataDisk"> > <sdb3=swap>

Rest hardware: AMD AthlonXP Barton2.2ghz, 1Gb ddrram, Nforce2ultra400(Abit NF7-S v2, g6800.

Post all output here. It should tell you that it at least found the linux kernel image.

[ShinobiTeno]

Sorry, >>`ed it to the tail of the first post. ):/

[Neo_The_User]

You might have to do some compiling. It's pretty complicated and requires a lot of typing on my part. I'm asking ahead to prevent frustration.

I'll get you started a little bit for now then let me know if your ready for the hard long complicated stuff. Might take 35 mins or it can be an hour and 30 mins.

not sudo apt-get install


sudo apt-get source linux-image-2.6.24-21-generic


and the rest is something I rather not get into unless you want me to.

[ShinobiTeno]

So you think its not that kernel image is unreachable for GRUB?.. -19 runs fine, -21 always gets "File not found". If you think theres a possibility to solve this with recompiling, lets give it a shot=) I`m ready.

[Neo_The_User]

It is reachable by GRUB. Most likely, The -21 kernel config has a different setup that the -19 kernel. I think they tried making the kernel smaller for faster boot-ups etc etc. Anyway... Now that you have the source code, CD to the kernel source folder. If you did it in your home folder (most likely) then type in



cd (kernel source folder goes here except without parenthesis)


Now for the dev tools.



sudo apt-get install linux-kernel-devel fakeroot build-essential makedumpfile qt3-dev-tools libqt3-mt-dev


Make sure your using the -19 kernel when doing this :lolflag:

Now that you have the dev tools you need and the kernel source, now its time for the compiling and configuring.

To get the -21 kernel using the same config file as the -19 kernel, type in the following command.



cp -vi /boot/config-`uname -r` .config


Now to graphically edit the config file (just a few things)



make xconfig


Now... go all the way to the bottom of the list located at the left side of the kernel config window. Look for kernel hacking. Turn off kernel debugging (unless you want to wait a million years for it to compile) which should then turn off "compile with kernel debug info"

Now click the save icon located at the top left of the kernel config window or hit Control S to save it.

Making the kernel:



make-kpkg clean


Compile the kernel:



fakeroot make-kpkg --initrd --append-to-version=-ultimate-killer-kernel kernel-image kernel-headers


Replace ultimate-killer-kernel with whatever you want. If you want it to say 2.6.24-21-generic then change it to generic. I personally thinks it cool in the grub menu when it says 2.6.24-21-ultimate-killer-kernel

Wait a long long time. WHEN IT SAYS DONE FOR A LONG TIME BUT IT DOESN'T GIVE YOU THE INTERACTIVE TERMINAL LIKE "neo@neo-desktop" (thats mine because its my name) THEN SCROLL UP AND DOWN THE TERMINAL TO WAKE IT UP AGAIN! THE TERMINAL FALLS ASLEEP KIND OF AT THE END!

Figure out what processor you have and how many cores it has.

If you have an AMD Phenom X4 64-bit Quad-core then after it compiles, type in
echo fbcon | sudo tee -a /etc/echo fbcon | sudo tee -a /etc/initramfs-tools/modulesinitramfs-tools/modules


export CONCURRENCY_LEVEL=5


I have a K7 AMD Athlon XP 2000+ and have no idea how many cores I have so I don't do the concurrency_level thing.

Load frame buffer



echo vesafb | sudo tee -a /etc/initramfs-tools/modules
echo fbcon | sudo tee -a /etc/initramfs-tools/modules


Now open up a file browser to where you had your kernel source or whatever. Inside the directory (not the folder of the kernel) of which the kernel source folder is in, find the kernel image and the kernel headers. It will say Custom-10.00 or something like that. It will be a very long .deb file. After you find them, go back in terminal and type in



sudo dpkg -i (kernel image goes here so drag it in via nautilus or something)

sudo dpkg -i (kernel headers)


In terminal, type in



sudo update-grub


If you still have problems type this in



fsck -y /dev/hda0


replace hda0 with hda1 or whatever if it doesn't work. Post output of fsck -y /dev/hda0 here.

[ShinobiTeno]

Much thanks for the guide!

I`ve been hacking in the kernel for some time and got it to work.
But the most important thing is after I installed it and did update-grub, stock -21 kernel magically started to boot... I did try update-grub before all this(right after kernel got installed thru automatic sys-update), and it didnt change anything...

Customized kernel that I built works, but I get PulseAudio warning-"unable to get connection(or something)" and the X server fails to start>complained on NVIDIA not integrated(I use them for 3D). Are there possibilities to make nvidia work using ubuntu reps, or I need to go to nvidia and get their drivers there and recompile the kernel with their script?..

What's on PulseAudio(in the case you're using it or know about)?

Other strange thing: In xconfig, I noticed ALSA to be turned off completely according to -19 stock .config... But it works in -19 nevertheless...

Im just currious about turning on PAE and (especially) recompiling for K7(I have 3200+ athlon(2,2ghz)) :)
