Ubuntu :: Kernal Panic On Boot
Nov 20, 2010
So I just installed the new linux kernel ( version 26) . On reboot there is a kernel panic with something like not able to mount root fs on 0,0. The older kernel works fine though. And btw while installing the kernel it did complain about not sufficiant space in /boot. I have got this message earlier, so I removed one of the oldest kernels. and i recently there has been package failure during installation of other packages. And one last thing, i noted that during the removal of the older kernel, there were lines in the terminal suggesting that kernel-26 had not been configured properly, so it tried to configure kernel-25 which also apparently failed.

I recently installed new hard drive and cloned old hard drive software onto it. The bootloader installs either linux or other operating system. Ever since the cloning, boot hangs. Words in the thread title are the last to appear before everything grinds to a halt. Just before the kernal panic message appears, "Initrd finished" is last line. Will have to try booting again to find more info before this.

I have a Dell Dimension 2400 I got at a yard sale. Has the typical 512MB Ram, 80GB Hard Drive, 2.4GHz Celeron and the integrated Intel video and audio. I decided to put Ubuntu 9.10. However I got a Kernal Panic while loading the live CD. It gets to the white flashing Ubuntu Loco. It freezes. The lights on the keyboard flash and it complains of a kernel panic.

I was unable to access the server and had to reboot it. When the server was booting after the Grub, it errored out withKernal Panic -not syncing Attempted to Kill init!!exec of init (/sbin/init/) failed No such directoryI reboot into the recuse mode from the CD and when looking for the installed OS.I got an error like thisFound OS but with errors.Mounting part or all of your system at /mnt/sysimage.. something of the sort. I've run fsk -y on the /boot and root drives and rebooted but still the same issues.Here is my grub.conf:
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file

System:
Ubuntu 10.04 Lucid; clean install; 32bit
When booting, I can choose 2 from 2 options (ignoring recovery mode):
- Ubuntu, with Linux 2.6.32-22-generic
- Ubuntu, with Linux 2.6.32-21-generic
(and then Windows Vista and Ubuntu 9.10 a couple of times) The newer version appeared with an update from Ubuntu a couple of days after installation. When booting from the first I get the following message:
Code:
Kernal panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) When booting from the second, Ubuntu loads without a problem.

I've got the following system:
Quote:
I've been having problems with the system ever since I replaced the motherboard. Moving slow and just generally acting 'wonky.' Well the other day I reached my frustration limit and wiped the HDD. Up to this point the HDD had been in 2 partitions, one for the DELL diagnostics and one for the OS, XP Pro.
I decided that I wanted to set up the system in a dual-boot during the rebuild so I created a two partitions using the Windows install. Partition one is the DELL Diagnostic partition, partition 2 is the XP Pro partition and partition 3 is to be the Linux partition. All seemed to go well with the Windows install. I got the OS up and running and got all the updates done and drivers installed.
I only have the one HDD in the system so I was going to have to make this dual-boot off of one HDD.
I had previously, within the past week or two, downloaded the .iso and created the disk for FC11.
I went through the install process and successfully installed Linux on the 3rd partition, or so I thought. When I attempted to boot into Linux I got the Kernal Panic error.
My grub file as it exists now is:
Code:
If I leave the file as is, I get the kernal panic error but the splash image works fine. If I try to change the 'splash image' and 'root' references from '(hd0,2),' then neither works.
I can boot into Windows XP from the setup as it is now.
I if I boot using my LoaS (FC 11 made at the same time as the images for the cds were downloaded) I can see the hdd and multiple partitions. There seems to be a 'boot' partion, the Linux OS partition, a swap partion, as well as the Dell and XP partions. Now I've tried changing the references in the grub file to reflect the different partitions, basically I've tried 2, 3, 4 and 5, everything but 0 (the dell diagnostics) and 1 (the XP Pro).
I've also re-wiped the HDD and started the whole process over from scratch, thinking maybe I'd hosed something up the first time, but being a firm believer in 'Always do what you've always done and you'll always get what you've always gotten,' and that one of the definitions of insanity it keep performing the same actions over and over and expect different results, I seem to be at impasse here.
Results from 'sfdisk -l'

I've been using Ubuntu now for 4 years and apart from getting the wireless card working on this laptop it has worked perfectly until now. I just loaded the updates and now problems, after switching on and selecting Ubuntu the next screen gives options
2.6.31-20 generic
2.6.31-20 recovery mode
down to
2.6.31-16 generic
if I hit return or let 20 load the next screen reads 1.414518 Kernal panic-not syncing :vfs : unable to mount root fs on unknown - block (8,2) Caps light starts flashing and only way out is to power down. If I select 20 recovery I get a screen full of info and then caps light flashing and only way out is the power button, if I select 19 it loads and works as normal. Is there a simple way to get it auto loading again as the rest of the family use this and are now Ubuntu converts and will not realise whats going on and will reluctantly load up windows.......

I originally tried Ubuntu 9.10 via a windows installation through Wubi. I had a VERY complex problem with a "Kernal Panic" due to an update through update manager and my system would not run proficiently. I wanted to know if that bug was exclusive to Wubi installations or does it also exist with this method of installation. I'm not going to update ANYTHING until I know for sure.

After I upgraded from 9.10, I restarted and waited. ubuntu boot screen froze after a little bit, and the my caplock and scrolllock started flashing (I believe this is the kernel panicking) Then I tried safe mode and it did the same thing when is was saying something about sensors. So I then went to grub and started it with an old kernel and it booted fine (without the splash screen though) what should I do?
EDIT: ok the kernel version it is not working with is version 2.6.32-21 and it does work in 2.6.31-21. Also, it now doesn't say anything about sensors. It panics after App-armor loads ans skips Firefox's profile (or something like that)

I'm a linux newbie so be gentle please. I'm on Lucid Lynx. Last night, the update manager installed updates to the linux kernel header. I'm not exactly sure what that means but it was one of the more important updates as it required a reboot.
This morning, my machine would not boot. After getting past the loading screen, my laptop hangs on a black screen. It was working flawlessly before yesterday. I can boot into recovery mode which appears identical to the regular mode, which works fine and is what I've been using. Also, I used a custom bootscreen, but it seems to have reverted to the default one that comes with the Lucid Lynx install.

At every boot I get an automatic bug reporting warning about the kernal. Not sure what is causing this or how to fix it. It is on a Dell d600 laptop.

I have a pc trying to install fedora. It is an amd downloaded and tried to install different versions of fedora. The latest i686 and will get to a boot screen and when selecting boot will lock up at the i386 start kernal command and blinky curser. Yes I am new to linux and may need some hand holding. I have however successfully installed fedora on other computers a while back which is why I am not sure what is going on. It may be a hardware mismatch. I will try to see if I can find another computer to install. I used a different computer and is working. The athlon computer is not working.

i used dual boot system (xp + ubuntu 10.04) and decided to replace them with jolicloud os and then it started In about 86% of jolicloud install it showed me error of hdd partition. I tried different versions of partion type, used also option to install on entire hdd - none of my tries actually worked (also with many hdd formating tries) so I was able to use only usb as live user for Jolicloud, and i burned ubuntu iso on disk - on boot up showed boot up error, i checked BIOS and everything seemed to be ok with boot order. So after many tries i took my old Gutsy Gibon 7.10 live cd. I first updated it with LTS version (8.04 Hardy Heron) and after that I updated it to 10.04 but it seemed to not finish when i saw some error in terminal and installer was exiting 13 minutes before finish then it had kernel panic - fuuuuck! After that i tried to download small versions of linux like Austrumi and puppy linux , but it showed me boot error or cd didnt even open install dialog without showing boot error.

I had a problem a couple of months ago after doing an update where something went wrong with the latest Kernal but I could still use Ubuntu by selecting another Kernal, now after doing an update last night and restarting.....nothing.... the screen reads:
GNU GRUB 1.97 beta4 Minimal BASH- like line editing is supported. For the first word TAB lists possible command completions. So if I press TAB and boot it says "no Kernal" does this mean UBUNTU is no more on my machine?

Edit: The PC is broken and I'll buy a new one. Don' bother reading this thread.
I have Kubuntu 9.10 installed on my Acer 7520g laptop. It used to work fine.
But recently my laptop has often went into kernel panic, sometimes at boot, sometimes after hours of normal usage. Today it has not been able to boot properly from HD a single time.
When I boot it up in recovery mode, it kernel panics and displays this (normal mode displays just the graphical progress bar, no text):
Code:
00010c0f
[ 9.620019] TSC f0ed3f8e6
[ 9.620019] PROCESSOR 2:60f82 TIME 1270650316 SOCKET 0 APIC 0
[ 9.620019] This is not a software problem!
[Code]....
I'm sure this is a pure software problem, because Ubuntu 7.10 LiveCD boots up normally and I got X, Gnome and everything working. So CPU must be working perfectly.
I read the logs in /var/log but there were no error messages.

I installed mythbuntu from a live CD on an old machine with an IDE hard disk just to play with it. It worked a treat, so I bought an Acer Aspire Revo R3610 and used dd to copy the old HD contents to the new one, and then gparted to resize the ext4 partition.
On boot I got - Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)
I checked every grub2 command and it all looked fine. I then tried booting the original kernel that the live CD installed (2.6.31-14) and it booted! I tried 2/6/31-17 again, and got the panic.
After much googling, I found a suggestion to do - sudo update-initramfs -k all -c -v and this worked.
Is this expected behaviour? One of the delights of Linux is that installs move smoothly between machines, but this one didn't. Was this due to the old machine using IDE and the new one AHCI SATA? How do I get an initramfs that's flexible and will boot smoothly on any given hardware?

when i was in office, something funny happened. my laptop power chord seemed to be disconnected and was running on battery power. i was away from desk and by the time i came back, laptop had gone to sleep may b due to battery getting drained.i packed up and came home, plugged in and booted but ubuntu seemed to give lots of erros and didnt boot. i went to my win partition, burnt the iso i had earlier downloaded and kept on win partition for safety. i booted off the cd and issued sudo fsck command from terminal. fsck did its job and gave a clean chit for my dev/sda5 (where ubuntu is).

I've been trying to get Ubuntu on my beloved 4 year old Acer desktop that's been chugging like a tank. However, after either a fresh install or upgrade, I would get the following error:"Kernel panic - not syncing: VFS: Unable to mount to root FS on unknown-block(0,0)".I've looked here and there, and one of the issues it would seem is the kernel not recognizing my hard drive if I'm correct. One of the suggestions was to upgrade the kernel however, I have no idea how to do such a thing if I can't get into the OS.

I decided to try Linux recently. I downloaded CentOS-5.3-i386-bin-DVD.iso. Installation was successful but the OS reports Kernel Panic while booting. At first I can see messages:
Memory for crash kernel (0x0 to 0x0) notwithin permissible range
PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not usin MMCONFIG
The OS continues to boot, but then shows kernel panic.
I tried to solve this problem during several days. I've installed the OS at least 10 times changing conditions. I tried x86-64 version, disabled PAE in BIOS, performed manual partitioning without LVM. The result is the same.
My PC has Intel Core 2 Duo E8400 CPU (no overclocking), 4GB RAM (DDR2-800), ATI 3470 GPU. Windows is working smoothly on it, I can encode video during several hours without problem. All fans are working, the system is not overheated. MemTest86 showed no errors.
I've installed CentOS on my laptop (Core 2 T5600 CPU, 2GB RAM, Intel G945 Video), it works nice, i like it very much.
For testing I've installed OpenSUSE 11.1 on the PC, everything is ok, I'm writing this message from it.

I have built a new server, now I am trying to restore my db from mysql. I have a backup that is out dated, I was hoping there was a way to copy the files over and have them work on the new installation. I can boot the server with the installation cd using recovery mode, I can get to the hdd and mount a smbfs share from the new server. I have tried to cp the files retaining the permissions and get a permission denied error, but if I copy without retaining the perms they copy just fine and do not work.
I have setup the new server with very close to the same version of all software. I have built a new instance of my service using all of the same users and passwords. I then backed up the new db and moved it over and attempted to copy the old db over. I did not copy it straight to the mysql folder as I did not share that folder out. Any other ideas to get this db recovered? What about getting my old server to run again just long enough to get a mysql dump?

I previously managed to install Ubuntu 9.04 using the regular Live-CD by using the no-ahci option. Now I am trying to install Ubuntu 10.4 LTS with an alternate install CD but even tho when i use the same options, I get a black screen then everything messes up and I get this: This is a video of what happens: [URL]
So I downloaded the regular installation CD and I had a big surprise again...The same thing happens except that its not white but purple. No matter which option I select its still the same. Note that this did the same thing when I tried to install Ubuntu 9.04 with the Alternate CD. I have a SiS motherboard. I tried OpenSuse just for the fun of it and it works!!! But the things is I don't like OpenSuse I would really like to make it work with Ubuntu.

We have not actually purchased support on a 2nd seat yet, so I can't go to them for this yet, and purchasing the seat may be silly if the machine can't run the OS.
I have tried several times to install RHEL 6 workstation onto a server machine. It has a dual drive RAID filesystem, whose configuration I had nothing to do with. The install procedes nicely but Displays a mdam error 127 before shutting down for the first real boot.
When booting a weird progress bar with at least 3 colors proceding at different rates displays for about 5 seconds followed by a very verbose kernel panic error which mentions tainted swap and scheduling while atomic. I suspect the error that caused the mess runs off screen too quickly to record.
Does anybody have a clue what might be happening? Even if I install minimal this happens so it appears to be a very low level hardware problem rather than a corrupt package.
I should mention that the machine runs on ubuntu 10.10 just fine, but my Lab PI wants to run it as a redhat system.

I am running Debian squeeze. A while ago I upgraded my kernel to 2.6.38 from backports. Just now I thought it would be good to upgrade to 2.6.39 from backports. Upgrade went fine, but after rebooting I get a kernel panics rightaway.
"No filesystem could mount root, tried:"
"Kernel panics = not syncing: VFA: Unable to mount root fs on unkown-block(0,0)."
This is the first time one of Linux installations halts/panics on booting, so I don't know what to do now. I tried booting the recovery entry from the grub boot menu, but same result.

I was finally able to install Fedora 11 x64 after choosing to only install packages from the repository on the install DVD. Prior to that when I had chosen tio install from the default online repositories, the install itself failed with a Python exception ( see my other post ). Now, however, once I boot after the install I eventually receive a kernel panic message, and failure. The exact same thing happened with CentOS 5.3 x64 after a flawless install. So unless someone knows what might be going on I will assume that Fedore, Red hat, and offshoots for x64 bit systems are just not for me. I have been able to successfully install the latest Mandriva and SUSE x64 Linux distros so whatever Red Hat/Fedora has done just does not work on my system.

It appears that I have really messed up my machine. I was trying to get matlab working on FC 11 and I ran into libc.so.6 issues, so I put an older file libc.2.3.1.so in /lib/tls/ directory and created a symbolic link libc.so.6 to see if the application would work. Unfortunately at the same time the system did some updates and the system hung, so I ended up rebooting, but now it gets stuck at boot screen (after grub) with a kernel panic - not syncing: attempted to kill init.I just need a way to get to the directror /lib/tls and delete the link and the older .so file I threw in there. How do I get this accomplished. I cannot get even to a shell from the boot screen.

I am trying to install Fedora on my computer but I am getting a kernel panic at liveCD boot after boot menu. It occurs to me for F13 and F14 (all x64, F14 x86 seems to boot fine but I'm trying to host a x64 guest OS on it so I need to get the x64 version to work)
My system specs:
Dual Opteron 265
4GB RAM
Asus K8N-DL (nVidia nForce Pro 2000, BIOS 1010)
I also tried to install F14 in some other computer (which worked flawlessly) and put the HDD into the computer in question, which gave me the same kernel panic.
