Hardware :: Trying To Debug Memory Error Lockup - Kernel Panic

Jan 31, 2010

I am having a problem with lockups on a new FC12 box (dual core 3 ghz, 4 gb memory, HDPVR, nvidia 8400gs). This happens reliably when replaying MythTV videos, but also randomly at other times using other apps. Usually but not always this is accompanied by a kernel panic (caps lock + scroll lock lights flash on keyboard).

I did a core dump with kdump and it reports:
Thread 1 (<main task>):

Cannot access memory at address 0xffff880028025b70I am in the process of running memtest86+ right now, and it's been through several passes without errors. I know it needs to run more, but given the reliability of this problem with MythTV video playback I am wondering if the problem could be in the video card memory. Any linux (or bootable) tester for video memory? All I am able to find are some things for windoze such as this. Also is there any way to track that address from the core dump back to a physical location?

Server :: Debug Out-of-memory Error After The Fact?

Jun 22, 2010

Last night a RHEL server in our cluster unexpectedly ran out of memory and became unable to perform its purpose. I say unexpectedly, because it had been purring away for ~385 days of uptime without a twitch. It has 16GB of memory, of which on average 2GB are in use. I see no unusual traffic in e.g. HTTPD log files. how to approach tracking down why this might have happened, with a view to preventing a reoccurrence.

Ubuntu :: 10.04 Kernel Panic-not Syncing And Failed Memory Test?

Aug 7, 2011

this is a dual boot XP/UBUNTU 10.04. while using XP, the computer rebooted itself. the GRUB's screen appears, but neither the ubuntu nor the XP option works.

Ubuntu gives this error message:

Code:
0.797795 kernel panic-not syncing: vfs: enable to mount root fs on unknown-block (0,0)

XP hangs on a black screen... and that is it (thanks for support windows!) UBUNTU 10.04 live CD hangs when the 5 processing dots appears bellow the ubuntu logo. hangs the same way with the processing bar in UBUNTU 9.04 live CD. memory check (memtest86) is showing thousands of errors right from the start.

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.

Fedora Hardware :: Kernel Panic During Installation - RAM Error

Sep 9, 2010

I have a system here that tends to have kernel panics during an linux installation, though I was able to perform a vista installation on the same hardware. Now I would like to ask what your suggestion for the cause of that problem is. Here a screenshot: [URL]

I suspect the hd to cause it:
-it is now over 7 years old
-smartctl displays over 16k read error and 0.5mio seek errors
(or are such high numbers normalfor that old disks?)
-the panic contains the string bad_area in the trace

But it might also be a RAM error, since the trace contains sth about page_fault and vista installs on the very same hdd and does not report any error messages (concerning the hardware, and I heard win doesn't complain about a bad RAM).

OpenSUSE Install :: Getting A Kernel Panic Error On Computer

Feb 13, 2010

It is my first try getting Linux on my pc which is an Acer Aspire Z5610. This is not the first time for me when I am getting an Kernel Panic error on this computer.

I looked up google hoping to find an answer and I found out that it may be my BIOS's fault. I currently have Windows 7 on this PC. I have a Phoenix BIOS and there is an update for it called "Bios Linux" on the official Acer support website.

OK, after this short introduction, that's the error:

I really hope to get support for this problem as I can not literally install any other OS to this PC than Windows 7 because they fail with Kernel Panic.

Tried other Linux Editions and even Mac OS Intel Edition and IAtkos V1 and V7 and they all give kernel panic.

Red Hat / Fedora :: Corrupted Libs: Kernel Panic Error

I untared a few libs on the wrong server (that's the when you're supposed to start laughing!) and I corrupted my server. Everytime it boots up, I get the following error:

I can I restore the original libs? I'm running RHEL 2.6.9-42 on a Proliant DL585.

Ubuntu Installation :: Kernel Panic Not Syncing / Relocation Error

Apr 15, 2010

I tried to upgrade Empathy from 2.28 to 2.30 via Synaptic but the upgrade always failed as there were some errors to do with the dependencies (libglib2.0* and others). The dependency issues were odd as it told me that Empathy wanted to install files that were older than the existing ones. So I decided to uninstall Empathy and all its dependencies, and re-install the whole (updated) package and it's dependencies from scratch via Synaptic. After the install, Ubuntu told me that there were broken packages and Update Manager kept on popping up asking me to run a partial upgrade to fix these broken packages. Well, the partial upgrade also failed (due to the same dependency issues , I suspect) so I decided that I'll run a full system update (as Update Manager had being bugging me prior to my failed Empathy upgrade). 486 Mb later, Ubuntu no longer wants to boot - it freezes on the splash screen.

When I start it in recovery mode, it spews out the various processes being loaded. Trying to run earlier kernels (2.6.31-19 / 17 / 14) from GRUB, in both normal mode and recovery mode does not seem to help.I am running Ubuntu 9.10, kernel 2.6.31-20-generic.

a) Is the problem to do with the kernel - did the update try to update the kernel as I note that there is a new stable release (2.6.33-2)? However, GRUB still indicates that the kernel is 2.6.31-20.
b) Would updating the kernel to 2.6.33-2 help? If so, how do I do this?
c) Is the problem, as I suspect, to do with the libglib* files? If so, how do I fix it?

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?

Ubuntu Installation :: Grub - Ran An Update And On Reboot Get A Kernel Panic Error

Mar 24, 2011

I have a new acer machine which runs fine on 10.10 mythbuntu desktop livecd. Install seemed fine.

Then I ran an update and on reboot I get a kernel panic error. Research on this reveals it as a very deep subject which can consume many hours, so I opted to reinstall.

This time with ubuntu 10.10. I've tried different CDs, liveusb. Same errors.

So, the question is this - where do I concentrate my efforts - somewhere ubuntu doesn't like this machine, or grub. Does a reinstall overwrite the grub install too? Or do I have a bogus grub install I need to purge before I will get anywhere.

Fedora Installation :: Error - Kernel Panic - Not Syncing: DMAR Hardware Is Malfunctioning

Mar 26, 2010

i study computational systems engineering.. and in my school (itlp) we've got fedora 12 installed in some of the computers.. and we use it to learn network administration and security. the reason of this message.. is that i want to install fedora 12 in my notebook (dv4-1525la vu068la).. but an error keeps poping up.. the error is the next one..

DMAR: No ATSR found
DRDH: handling fault status reg f0003d63
Kernel panic - not syncing: DMAR hardware is malfunctioning

and though i have looked in bugzilla.. there is no help for me there.. they say.. "press tab in the welcome bootscreen when you are about to select whether to install or restore an existing system and write intel_iommu=off and press enter" but that does not really helps.. it just does the same.. in some blogs they say "upgrade your bios".. but i say.. then why i can not install the olders distributions with my "old" bios.

Ubuntu Installation :: Error - Kernel Panic - Not Syncing: Attempted To Kill Init

Jun 8, 2011

Today I was upgrading my netbook with Ubuntu 10.10 on it to 11.04 via the Update Manager. I got a few errors and the Update Manager seemed like it wasn't continuing, so decided to exit it. It didn't respond so after a while I decided to restart the netbook. However the on/off/standby/restart, etc. button in the top right wasn't responding either, so I decided to force a shutdown with the power button on my netbook. Now Ubuntu doesn't start up, and gives me an error along the lines of:

Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.35-28-generic #50-Ubuntu Now could I in some way repair my Ubuntu installation while still keeping the files I already have on my computer? Maybe via booting from a flash drive or something...?

Ubuntu Installation :: From A USB Flash Memory Stick - Warning "VFS: Cannot Open Root Device "sda6" Or Unknown-block(0,0)" And Kernel Panic On First Boot

Apr 24, 2011

I am trying to install Ubuntu 10.10 from a USB flash memory stick. It works fine until around 95%, where I get the following warning/error:

[Code]....

I click OK and the installer seems to finish nicely, except the terminal throws several errors along these lines (see photo):

[Code]....

I tried also with 10.04 LTS, the difference being that the install warning appears two or three times instead of once. Some results from googling (Ubuntu Forums, Ubiquity bug) suggest unchecking the initial update options. I am going to try this but I'm not sure if I'll be able to get the boot loader right (there seemed to be problems with this).

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.

Fedora Installation :: F11 Installation Error Kernel Panic - Not Syncing

Jun 10, 2009

I am trying to install Fedora 11 from the full DVD iso on a system using an Intel D945GNT motherboard with a dual-core 3.2GHz Pentium D installed. The installation hangs quite quickly and produces the error "Kernel panic - not syncing"... The previous line is something along the lines of "EIP: [something] intel_i915_configure() [something else]". I have tried many different kernel boot options, such as acpi=off, nolapic, nommconf, and the like, but to no avail. It seems as though this has something to do with a memory mapping conflict due to the allocation of video memory for the on-board graphics chip, but I'm not at all certain about that.

Installation :: Boot Error Kernel Panic Can`t Boot Cdusb

Sep 2, 2010

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.

Hardware :: EXT3 Aborting Journal - Kernel Soft Lockup ?

Feb 2, 2011

I have a system running CentOS 5.5 (194.32 Kernel) that has been working fine for about 8 months. I found it stuck one morning dumping a Soft Lockup Kernel message every 10 seconds and have been trying to find out what is going on - here is what I've done and found.

System is a Core i3 with 4Gb DDR3 ram and 2 1.5Tb SATA drives - everything is less then 1 year old with not too much load (this is a backup system for my server - a twin and the other works fine)

Intel Mobo: DM55HC

Rebooting the system (after doing a fsck on the drives with lots of errors) it runs for about 20 hours or so and then drops back into this problem.

Prior to going into the soft lockup it reports that the Journal has aborted on one drive or the other and drops into a Read Only FS.

There is nothing in the logs apart from the aborting journal message and the soft-lockup)

Tried fsck with badblocks check on the 2 mountpoints for both drives (dunno how to check the swap partition) - nothing I could see there.

I have tried memtest for about 36hours. No errors

I ran smartctl long tests on both drives. No Errors
