Ubuntu Servers :: 8.04 - Kernel Panic On Boot Even In Recovery Mode
Feb 18, 2010
I have a 8.04 x64 server installation that is receiving a kernel panic on boot no matter which kernel I choose even recovery mode.

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 attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?
I am using RHEL 5.4 in VMware. Recently i have made changes in /etc/sysconfig/selinux and made it to be in "enforcing mode". Now when I rebooted my system, It is showing the following error: "Unable to load SELinux Policy. machine is in enforcing mode. Kernel panic- not syncing: Attempted to kill init!"
After a large update of software I can nolonger open Squeeze. I get past the grub screen however before the gdm starts up the screen goes blank and stays that way. I have only one kernel showing on the grub screen.
I tried in Recovery Mode: Ctrl+Alt +F keys with effect and startx returns a blank screen, this is why I though to try loading another kernel to see if that helps. I'm using a Acer Laptop.
My question is: Is it possible while in Recovery Mode to load/install another kernel os that when I get back to the grub screen I have another kernel to try to boot into?
Today I wanted to make a backup of my Ubuntu server. Since the program wasn't working for me, I rebooted my computer and right now it wont boot. Now I entered recovery mode and I'm trying to recover my /var/www and /etc/mrtg folders. I want to copy them to my USB-Stick but Ubuntu wont do this.
The command I tried: Code: cp -r /var/www /dev/sdg1/www I already created the folder via a other system. I also tried to mount the USB stick: Code: mount /dev/sdg1 /mnt/usbe But im getting the following error: error while loading shared libraries: /lib/libsepol.so.1: Invalid ELF header.
I'm having a huge problem right now and I could use some help deciphering what's wrong.I can't get my system to boot (see signature) and even the recovery mode is buggered. henever I try to boot, all I get is a flashing underscore. This is the same for both the normal and recovery modes Kernels. I've run the boot info script from a live cd and I've attached it to this post.
I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

This is an urgent problem. I removed my propreitary ati display drivers because I had to update them but I don't know what happened. Now I can't boot. The screen shows the Ubuntu splash screen but then the login screen does not come on. I get a blank screen. Worst of all, I had removed Recovery entries from the grub so I can't boot into recovery mode so easily. It's urgent. I don't want to reinstall with my exams a week away.
as Ubuntu is my only OS on this box.I had this PC running as a server for a few months with few reboots.I installed updates as usual yesterday, and hadn't changed anything configuration-wise since the last reboot. Well last night this server that I was running was moved to another Windows box and so I finally got to shut this PC down for the night. In the morning, I was greeted with an endless splash screen. It went on for 20 minutes without anything. I did update the kernel through update manager.
So what do I do? This machine has a 1TB HDD with a lot of very important data on it--reformatting is not a considerable option at this point. Which is bad because I don't know what else I could so when even recovery mode isn't working...
I had many problems with installing kubuntu 11.04 on my laptop HP Elitebook 8560p and after downloading different iso everything works well, but sistem freezeout and would not reboot also in recovery mode that would load untill Recovery menu when system won't responde.
this is what i did i downloaded the latest stable kernel archive from kernel.org and extracted the archive into the download directory (i don't think that matters though) then i downloaded and installed the ncurses archive (needed for menuconfig) then i opened a terminal and navigated to the directory that was extracted from the archive and issues the floowing commands
After upgrading to 9.10 Karmic Koala, my Amilo Laptop (AMD64) refuses to boot. I installed GRUB2 which works fine for my WinXP ... and Karmic will boot in recovery mode.
When trying a normal boot, I get a black screen. CRTL-ALT-F1 yields just a blinking cursor. The system will immediately reboot when pressing CRTL-ALT-Entf.
When booting in recovery mode, I choose "Resume normal boot" from the menu, log in while in cosole mode and enter "startx" ... and the grafic environtment works fine!
Why does the system work in recovery mode, but does not start with a normal boot?

Here's some information on my system:
cat /proc/version
Linux version 2.6.31-17-generic (buildd@crested) (gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu ) #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009
I'm posting this in the "General Help" category, because it doesn't really fit in another one. Feel free to move this thread, if it's the wrong place. I'm having a problem with my Linux. Since today, my Kubuntu 10.10 (running on an Dell XPS M1530) doesn't but anymore. Neither normal, nor recovery-mode is working. I also tried out different kernels in the grub-menu without any success. The boot-process stops at:

I have GRUB on my laptop with Ubuntu and Windows 7. GRUB and Windows 7 seem to boot just fine, but recently, Ubuntu doesn't boot. My suspected cause is simply because I've often shut down unofficially. My laptop doesn't have a battery, and even the AC connection is awry, so as soon as an accidental disconnection or something occurs (because it too is broken), it'll essentially shut down.
I try booting Ubuntu, and it doesn't boot. I think I see that Ubuntu and the dots page, but it'll hang there (and I waited overnight). Immediately, I want to run an fsck, but I seem to be unable to, so I run Recovery Mode. I always get a forever loop of a bunch of stuff that doesn't make sense to me, but this is one thing that I always see (or something similar).
I started a thread over in installations and upgrades in which I was trying to upgrade from Ubuntu 10.04 to 10.10 using the upgrade manager. My computer froze in the middle of the process, requiring me to restart my computer. When I try rebooting Ubuntu, I get an error message "The configuration defaults for Gnome power manager have not been installed correctly" and then a blank screen. No mouse pointer, no cursor. It will not take me to the Ubuntu desktop screen. I've already found the sudo commands I can run to try and fix Ubuntu. They are as follows:
sudo apt-get clean (If the problem is not having enough free hard drive space) sudo dpkg --configure -a (If the problem deals with the upgrade installation process)
However, what I can't get is the terminal to come up to run these commands. In the other thread I started, someone mentioned that in the Grub menu, you can choose "recovery mode", hit "enter" to boot it, and it will give you a menu of options to choose from. However, when I choose "recovery mode" and hit "enter", I do not get a menu but instead 3 pages of data about my computer that ends with this:
"Begin: Running/scripts/init-bottom... Done. "
It gives me a blinking cursor at the very end but I cannot type anything and I cannot page up to see the 3 pages of data. What I am looking for is a way to get to the recovery mode menu OR somehow open up a terminal so I can run the sudo commands. My computer automatically logs me in, so I do not get a login screen and Ctrl+Alt+F1 does not work for me. Anyone know how I can open a terminal with only access to the Grub menu? Perhaps a BASH command that I can use in the command line that will open up a terminal? To summarize: My computer does not boot Ubuntu. I get an error message followed by a blank screen. It does not go into the desktop screen so I cannot choose Applications->Accessories->Terminal.
My Grub menu consists of Ubuntu and it's version, Ubuntu and it's version with recovery mode, memtest, and Windows XP (I have a dual boot system). In the Grub menu, I can select "e" for edit, "c" for command line and "enter" to boot either regular Ubuntu OS or Ubuntu recovery mode. "Sudo" commands are not recognize if I choose the command line for either Ubuntu OS or recovery mode. I have a Live CD for 10.04 but you cannot run sudo commands because you do not have access to root on the Live CD.
i'm a recent convert from windows and my first few days with this os have been great. to think i've been living in the dark all this time...
anyway, my question is about the boot screen in bios. normally it booted up thusly:
ubuntu-linux generic [...] ubuntu-linux generic [...] (recovery) memory thing windows xp
but today, the boot screen showed two instances of ubuntu generic, its recovery mode, and the memory thing (i forget what it's called exactly. do you know what i mean?). i installed the os only once.
So I have been messing around with the new 10.04 and I managed to screw it up. When I started to log off, I closed the lid to my laptop so it would hibernate, but instead the screen went black and I could only see the cursor. It stayed like that for several minutes so I shut it down manually. When I booted it up again, it froze on the splash/loading screen and I haven't been able to boot it since. I've tried to boot in recovery mode, but I think my campus internet interferes with the downloading of the necessary files from the internet. Is there any way to boot a recovery mode from the install disc? Or am I SOL?
I have an encrypted file system and recently installed proprietary ATI drivers for my graphics card. The moment I did that, Ubuntu boots with a black screen. Now I'm attempting to get back into the OS to remove the drivers, but when I choose Ubuntu Recovery Mode from the grub boot screen, it shows some dmesg output and then the screen goes black. Whats interesting is it doesn't even ask me to decrypt the hard drive (like it normally does). how I can get back into the OS to remove the drivers?
I installed ubuntu 10.04 by wubi. It works perfect until I installed and ran "startupmanager". I find that I can't enter ubuntu, even in recovery mode. The screen keeps showing "rstslog main process ended, respawning [fail]" and other text
My friend asked me to look at their laptop as it was not booting up. I checked it and found that you could not even boot into safe mode. I have used a windows boot disk to try and sort any issues but this has not worked. The problem is he never made the recovery disks by the manufacturer so I cant reinstall windows. I can access all the files on the hard drive when running Ubuntu. So what I need to know is it possible to run the manufacturers program to make the recovery disks from Ubuntu.
This started a few days ago and I checked back through recently installed packages and nothing looks related. If I boot into ubuntu normally, plymouth looks a mess, but then things boot fine but while the mouse is showing and ubuntu goes about with connecting to networks and so on, but it doesn't register the and input from the mouse or keyboard. It will sleep if you press the power button, but its no more responsive after waking up.
If I boot into recovery mode, and use the failsafe graphics option then everything runs fine. Apart from 3D graphics being pretty slow, which I can kind of understand. I get the same behaviour on all of the last three kernels. I'm running the latest maverick on an HP 6715b. i386 version although the processor is 64 bit compatible. 2Gb RAM.
I'm new to ubuntu and I wanted to setup a headless server (Asus Hummingbird, 2GB RAM, Ubuntu Server 11.04). The installation was successful but: After I tried starting my server without any connected monitor, the server did not start -> I run into a kernel panic (if I connect the monitor after a while I can see the messages on the screen, Keyboard lights flash...). What do I have to do to get the machine running without any monitor? My second problem is, that the Network is always powered down on system power down -> no WOL is possible. Is there an easy way of enabling the WOL function? I tried several things from different tutorials but nothing worked...
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 prepared a ISO from ubuntu 8.04.3 server using which kernel 2.6.24-24-server.My installer file is in initrd is iecho Preparing to install cd / mount -nt tmpfs tmpfs tmp

I tried to make Compiz work using the experimental 3D support of the free Nvidia driver, because I am suffering from a bug in the proprietary driver (click here for launchpad entry). The free driver I mean is the one that shows up as "Experimental 3D support for NVIDIA cards" in the "Additional Drivers" manager (note: for some reason, this option will only present itself when no proprietary driver is currently active).
Now the strange thing is: the driver does not provide 3d support, and behaves generally awful (lots of glitches and so on) when I boot my system normally. But when instead I boot from the grub menu into recovery mode, then select "failsafe graphics", and then select "restart X", the whole thing works perfectly! So now I am running the experimental 3d driver, I have compositing working, 3d animations on docky. Somehow, the failsafe boot sequence does something right that my normal boot sequence does not. When I reboot in normal mode, everything is screwed up again.
I have no idea what statistics about my system I should include here, because I really have no idea what could possibly be wrong. I am running 32bits Natty in Classic mode, on an Ahtlon Dual Core 4850e machine, with a GeForce 6150 LE graphics card. These are the normal and recovery entries in my grub.cfg:
Code:
menuentry 'Ubuntu, with Linux 2.6.38-8-generic-pae' --class ubuntu --class gnu-linux --class gnu --class os { recordfail set gfxpayload=$linux_gfx_mode insmod part_msdos
I've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.
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 am not able to start gnome desktop though most gnome applications work in icewm and xfce4 newly installed. the system config edit button i cannot understand what keys where to edit? how do we reinstall gnome fully? by the way my system is

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?
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.
