Kernel Panic in Ubuntu 7.10

CrownAmbassador · 02-12-2008, 10:16 AM

I've been trying to get my 2.6.24.2 kernel up and running, but had no success. I've done a lot of searching around and tried the following:

I installed the kernel as shown here. After that I ran the following command to update GRUB:

Code:

sudo update-grub

After doing that, this is how /boot/grub/menu.1st looked:

Code:

root            (hd0,4)
kernel          /boot/memtest86+.bin
quiet

But every time I got the following error:

Code:

[- 29.172344] pnpacpi: exceeded the max number of mom resources: 12
[  29.791290] kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

There is no initrd image for the 2.6.24.2 kernel in /boot. I was told that this is not always neccessary, but as I could not get the kernel to work anyway, I figured I'll make a initrd image to see if it works.

I used the following command to make the initrd image:

Code:

sudo mkinitrd -o /boot/initrd-2.6.24.2.img 2.6.24.2

Then I edited grub so that it uses the initrd image:

Code:

But then I got this error:

[14.784127] kernel panic - not syncing: Attempted to kill init!

I've seen a website where it said to set the following to "Y" when configiring the kernel:

Code:

Device Drivers->Multi-device support (RAID and LVM)
Device Drivers->Multi-device support (RAID and LVM)->Device mapper support
Device Drivers->Block devices->RAM disk support->Initial RAM disk (initrd) support

I found a place to enable RAID support, but not LVM support.

So, nothing I tried worked and believe me I tried. Can someone please help me with this?

Your going to probably have to switch your root=UUID... to a root=/dev/hdXY to use the kernel that you have built. Either that or you are missing drivers or file systems in your kernel configuration. If you compile drivers or file system support needed to get your system booted as modules you must make an initrd image so that the kernel can get to these drivers before it mounts the root file system.

Find a better distro to build your kernel against - too many roadblocks with the "mega" distros.
I use (variously) Arch, Gentoo, Slack - in that order.

There is a "sanctioned" way to do a Ubuntu build - have a look here. There is a link at the bottom for kernel.org source trees that will serve you (much) better than that you tried.

Okay I am completely confused here now. I already have the source installed and now that site is telling me to get it via apt. I can't get the 2.6.24.2 kernel via apt.

CrownAmbassador · 02-13-2008, 06:55 AM

Sorry syg00. Started looking at that site instead of the site listed at the bottom of it. Compiling now.

CrownAmbassador · 02-13-2008, 08:41 AM

Great! Thanks Syg00. Got it up and running. But now my sound aint working. Is there a command I can run or something to fix the problems that comes with installing a new kernel?

Ok problem. Now I can't get my Vodafone app to start up. It just does nothing. Even if I go alt-f2 and run as terminal, the terminal opens and then closes again before anything can be displayed. Idiotic old me have already uninstalled the old kernel. I've got ADSL at work that works fine, but now I'm home and for the time being I'm uing a USB 3G modem till I get my internal card to work. So at this stage I need that app. I tried installing the app using the live cd, but there is dependency problems that it needs to go online to fix! So I was forced to boot Windoze up! Hating it! Anyone here feel my pain? Lol! Help will be appreciated!

I'm still getting this error when starting up too: pnpacpi: exceeded the max number of mem recources: 12, but it goes past it and starts up anyway.

Thanks,
Conrad

Okay... I guess nobody knows. Can some one tell me how to change all the 2.6.22 packages in my repositories to 2.6.24 please?

CrownAmbassador · 02-14-2008, 06:46 AM

Reinstalled my kernel to the newest one off this Ubuntu website. Gives awesome instructions on how to update without compiling and fixes the sound issues too!

But I still have the problem of the Vodafone app not starting up. When the modem is in it doesn't start, but when it is out it does!
