General :: Kernel Panic After Updating 2.6.37-r4

May 3, 2011

I use gentoo linux and some minutes ago I thought to upgrade my kernel version. I had 2.6.36-r5 and I want to set 2.6.37-r4. After merging gentoo-sources I did this:

# cd /usr/src/linux
# make menuconfig
# make && make modules_install
# mount /boot
# cp arch/i386/boot/bzImage /boot/bzImage-2.6.37-gentoo-r4
# module-rebuild populate
# module-rebuild rebuild

At the end I changed the /boot/grub/grub.conf file. The last two commands are for reinstall modules that are not included in the kernel source. After rebooting the system this is what it printed out and stop loading.

sd 2:0:0:0: [sda] Attached SCSI disk

General :: Kernel Panic In 64bit Arch Linux After Kernel Recompile - 2.6.35-rc3

Jun 15, 2010

I have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.

Running Arch Linux 64bit, most recent version.

Kernel Output:

Code:

My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are. Now thinking it may be a memory error so will run a check when I shutdown.

General :: Getting Info On Kernel On Another Disk - Kernel Panic Error 6 Ext3

Feb 13, 2011

Dell laptop booting from a USB stick with a CentOS 5.5 minimum installation.

Uncompressing Linux...OK, booting the kernel.
Red Hat nash version 4.2.1.13 starting
sda: assuming drive cache: write through
sda: assuming drive cache: write through
mount: error 6 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
umount /initrd-dev failed: 2
Kernel panic - no syncing: Attempted to kill init!

1. Does minimum installation not drop on a kernel or initrd with ext3 support? I can't imagine that's true, but have to ask.

2. The USB stick is single partition ext3. Maybe there is some limitation specifically related to USB stick booting that requires boot to be FAT16 or FAT32? Except the CentOS 5.5 installer refuses to let me install on either FAT.

3. How can I do the equivalent of lsmod on a linux installation that will not boot? i.e. I have CentOS x86_64 running in VirtualBox, I can plug the USB stick in there, so how do I get information on the USB stick's kernel and initrd if I can't boot from it?

4. Is it possible to rebuild the i386 based initrd on this USB stick, when the computer is not booted from that stick, with a system that's x86_64 based?

System Info:
Dell Latitude i686 Laptop which has run CentOS 5.5 and Fedora 12,13,14 in the past, and boots from Fedora 14 Live CD transferred to a USB stick. So I know USB booting is possible on this machine, and this stick.

The process of creating the stick:

CentOS 5.5 i386 on a USB stick. Old Dell i686 laptop which has previously run CentOS 5.5 installed from DVD, and has successfully booted from this same USB stick holding transferred Fedora 12,13,14 Live CDs. CentOS 5.5 was installed onto the USB drive directly by the CentOS 5.5 DVD installer (running virtualized in VirtualBox 4.02 on Mac OS X 10.6.5.). No errors or complaints during installation.

For whatever reason, the installer did not do some things correctly. First Grub wasn't working correctly, I got that sorted out and have the Grub+CentOS splash screen, it finds vmlinuz and the initrd, and then I get a kernel panic.

Ext3 was built into the kernel and that's why I'm getting this message. I do not know how the installer would have dropped a kernel or initrd during instalation that that don't contain such a basic thing that obviously comes in linux kernel 2.6.18-89 EL.

General :: Tried To Install Bcmwl-kernel-source And Now Getting Kernel Panic

Jun 25, 2010

I am running an Hp Pavillion dv6000 with the Broadcom card that never seems to work for Linux. I recently talked with my friend who said he found a way to get it work.following his instructions I opened Synaptic and checked the package bmcwl-kernel-source to be installed.I went through the process of it all and it said it had install successfully. I restarted the computer and when I tried to enter my operating system I got this error "Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block(8,1)"
I have previous versions of Linux on my computer so I can still get in to those if need be but I don't know how to undo what I did or why it isn't working for that matter. Does anyone have any ideas as to why I am getting this error and how I can fix it?

General :: Kernel Panic - Not Syncing - No Init Found - Try Passing Init - Option To Kernel

Apr 19, 2011

Im am building a Linux distro. It will be very tiny and fast.

I only have a minimal linuxkernel (bzImage) who is 1,2 mb big. And then I have Busybox who is 174,6 kb big.

The commands in busybox is: cd, ls, mkdir, rmdir, wget, httpd, clear, rm, poweroff, halt, reboot, fdisk, mount, umount, free, and cp.

When I compiled the kernel i use initramfs/initrd function and point it to a folder where initrd/initramfs source is.

The kernel works OK with others initramfs/initrd files. But not with my own.

Quote:

Here is how the end of the kernelcomplie look like.

Quote:

Here is my init file who is the initrd/initramfs source.

Quote:

The initramfs folder contains "bin" (folder) and "init" a file. No more.

The problem is that the kernel cannot find/read init file.

General :: How To Tell When A Machine Is Fsck-ing And Hasn't Had A Kernel Panic

Jul 31, 2011

I have a server with Debian on it that I regularly reboot after upgrades. Sometimes (on schedule) fsck will check a disk when the computer is booting. With the exception of sitting in front of the console to observe the fsck, how can I determine the difference between a problematic halt and an fsck (besides waiting out the fsck, hoping it is an fsck)?When I send the computer down to reboot, I will usually have a terminal window open pinging the computer so I know when it has come back up. My first thoughts drifted to fantasizing about hacking fsck to respond to pings with some special magic byte so you could tell via ping that a computer was fsck-ing, but I'm thinking there have got to be easier ways..

General :: Switching Hard Drive Causes Kernel Panic?

Aug 12, 2010

I had an old Dell Precision 470 with 2 hard drives, a 250GB boot drive with Red Hat installed, and a 500GB hard drive with data on it. Both of these are SATA. The computer died and I have replaced it with a Dell T3500. I was hoping just to move the hard drives into this computer and let generic drivers take over until I make the necessary changes. Unfortunately, I get the following kernel panic message after POST:

VFS: Cannot open root device "Volume00/root" or 00:00 append a correct "root= " boot option Right now the arguments to boot from the hard drive are:

ro root=/dev/Volume00/root hdc=ide-scsi hdd=ide-scsi

General :: Ubuntu Install Freezes / Kernel Panic

Jul 24, 2011

Yesterday I decided to dual-boot windows 7 and Ubuntu 11.04. I successively instaled Ubuntu the first time using a flash drive. However, I found that I had made the partition for Ubuntu way to large. Having no idea what to do, I messed around with the partition sizes. Through a series of... mistakes, I deleted the two (the main space and swap space) linux partitions. When I restarted my computer I got the "partition not found" error. So from there, I burnt another ubuntu disk, (the flash drive I used had been reformatted for use on an Xbox) I am able to boot a live version of ubuntu on my computer. However, when I go to install Ubuntu, something goes wrong. After copying all the files, it goes into kernel panic about not syncing, and freezes.

I had looked up some advice on the web, and they said that it might be a memory error. However, Ubuntu 11.04 does not have the memtest86 or whatever, (at least that I could find) So I took out the smallest RAM stick (1 gig, leaving the laptop with 2 gigs of RAM) and it still freezes.

I included the story to see if I did something wrong with any of my steps that may have permanently done something bad to it.I know it does not sound like it, but yes, I only installed Linux yesterday, therefore, still a newb.

General :: Kernel Panic On Boot - Authentication Process Failed

Feb 22, 2011

I got home today to find that my KDE login screen would not let me log in. It said the authentication process failed or something and I needed to terminate the screen lock process manually. So I go over to another virtual terminal and try to log in. As soon as I enter my user name, a bunch of errors come up and I am unable to log in. "This can't be good" I think to myself, and reboot.

I am greeted by this error upon booting:
The error says that it says it cannot find /sbin/init. I loaded up a Ubuntu live CD and verified that /sbin/init is indeed present and all my other files still seem to be there. I tried booting into arch fallback on grub but that didn't work either. Midway through the day I SSHed my desktop from my phone and started it doing an upgrade. I was able to login.

General :: ACPI Error & Kernel Panic On Boot - Fedora 12

Jan 7, 2010

I just installed Fedora 12. When I boot, only the following three lines are printed: pnp 00:09: can't evaluate _CRS: 12298 ACPI: Expecting a [Reference] package element, found type 0 Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) I first installed Fedora using a RAID 1 setup that mirrored each partition, so I thought the problem was coming from GRUB and confusion from what to boot off of. However, I reinstalled Fedora using a simple single drive setup (left the second drive without any partition), and the same error was returned. Is this an ACPI issue with this particular motherboard/BIOS? Any ideas for how I can fix this?

General :: Unable To Boot On Vmware Workstation 6.5. Kernel Panic

Aug 7, 2010

I'm unable to boot the LFS-6.6 which i've built on a vmware workstation 6.5. i had no trouble in installing all the packages and have managed to run all the test suites successfully w.r.t stable LFS-6.6. while booting i get 'kernel panic' and it says unknown device /dev/sda1 and unknow block (0,0). i've only one primary partition without any swap partition. i've a label assigned to /dev/sda1 and have included it in my fstab file. device.map shows 2 entries:

One for the floppy and the other for my harddisk which is- hd0 /dev/sda. this is for the 2nd time i'm stuck at a point after perfectly installing all the stuff as mentioned in the LFS-6.6 book. i've also noticed on this website the many users have similar type of issue. it would be great if somebody could help me.
note: while configuring the linux, i've inbuilt everything required for my system, including support for ramfs and other required filesystems, scsi driver etc.

My host machine is on a intel core 2 duo processor. my virtual scsi hard disk is 3 GB in size and is a ext3 fs. scsi is configured with LSI Logic which is recommended by vmware while adding an hard-disk.

Red Hat :: RHEL4 Strange Kernel Panic On Boot - Kernel Update No Solution

Dec 31, 2008

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.

General :: Boot Disk - Returns Kernel Panic - Not Syncing Cpu Context Corrupt

Mar 6, 2010

I am a Windows 7 user. I have two machines a laptop & a new bench top. Both machines run & boot Windows 7 very well. I use a very good program to clone my Hard Drive to an external USB drive. called Macrium Reflect. It is free and is a dream to use & very fast. This program creates a Linux based boot disk, which will allow you to find a backup clone file on an external drive to restore your hard drive. It works a treat on my laptop & has saved my bacon many times when I have messed things up fiddling with the registry etc.

The problem I am having is that my new desktop will not boot from the start up CD & returns the error kernel panic,not syncing cpu context corrupt. & then just tries to reboot again. I don't know what this problem relates to whether it is the computer hardware or the Linux CD or both. My laptop with the same OS does not have a problem, It is an Acer Aspire 5920G with 1.6ghz Intel dual core processor & 2gig Ram. The bench top has an Intel Dual core 3.3ghz processor, Zotac mother board & 4gig of Ram. both machines are running 32 bit OS.

I have browsed through the posts on this forum with people having the same error at boot, but as I am not using Linux & only using a boot CD I didn't think it appropriate to but into their threads. So I am hoping if some one can tell me is this a hardware issue or a Linux/New dual core CPU/ or Bios/Mother board issue. If it is a Linux issue then my Laptop surely would not boot would it? My bench top is only a week old and guaranteed, should I be sending it from Adelaide back to Sydney(purchased online from MWave) for fault inspection? or just take to a local Technician for a diagnosis. I am not having any hardware problem running Windows 7.

Slackware :: Kernel Panic After Upgrading Slackware64-current To 2.6.32.x Kernel?

Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot.

General :: Kernel Panic - Not Syncing: VFS : Unable To Mount Roof Fs On Unknown-block Error?

Apr 21, 2010

I downloaded the ubuntu-9.10-desktop-i386.iso file from the website, extracted it, and ran the Wbiu.exe file - it prompted to get my info and then restart. Upon restarting, I then had the choice to run Windows or Ubuntu, and I've been running Ubuntu ever since.

I ran into some speed-bumps. Upon entering the Ubuntu option at my start-up prompt, I go to another prompt asking me to choose from: Ubuntu, linux 2.6.31-20 Generic Ubuntu, linux 2.6.31.20 Recovery mode Ubuntu, linux 2.6.31-14 Generic Ubuntu, linux 2.6.31-14 Recovery mode Windows 7 installer Windows Vista installer
I've been choosing the very first one, the 31-20 generic, but just this morning after downloading some programs from the Synaptic and transferring a few Gbs of music, I received this error prompt: Code: [2.879604] Kernel panic -- not syncing: VFS : Unable to mount roof fs on unknown--block (8,2) After that, I've been running the 2.6.31-14 generic installer. I have no idea what any of this means and I've spent time crawling through threads trying to figure it out. I mean, it still WORKS but I just help but think I've done something very wrong. ALERT: SUDO PASSWORD QUESTION

I hope the cautionary sign above has dispelled any annoyed gurus who have answered this question dozens of times before. I've crawled through my fair share of threads concerning this, the best corollary being the following: forum/linux-newbie/157773-solved-sudo-password-errors-usb-internet-issues.html; which, strangely enough, was never really solved. Like the user in that thread, when I access the terminal and type in a command, the next line invariably states "[sudo] password for jacob' -- when I hit enter and type in the long list of possibilities I've read (read: sudo, su, su root, su passwd, sudo passwd, sudo root, et al.), alas, nothing happens but the same statement.
