i have tried going through this old post but its still not working ... tried googling but i do not seem to find any conclusive solution for this. [URL]i am getting this error during boot time:
there is no immediate effect due to this but after sometime the HDD goes in read-only mode. have tried changing bios setting from IDE to AHCI, did a disk check using hiren boot disk which did not give any errors.even now the error still persists. Linux 2.6.18-164.el5PAE #1 SMP Thu Sep 3 04:10:44 EDT 2009 i686 i686 i386 GNU/Linux CentOS release 5.4 (Final) i know i should probably upgrade my kernel but i see people with latest kernel also facing the same issue (mostly with samsung hdd but mine is seagate)

I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php -rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.
recently I'va bought PCI adapter for extending ATA devices [URL], connected disk (WDC WD1600JB-00REA0, ATA DISK drive). Everything is fine except switching off. Sometimes it freezes, sometimes it takes longer time (more than 30 sec). Everything goes well - except the last step (when appears "Rebooting", or "Switching off" on console). I didn't add any extra boot option into /boot/grub/menu.lst
after upgrading ClamAV to version 0.97.1 and run the command Code: clamscan -r -i / --exclude-dir=^/sys --exclude-dir=^/dev --exclude-dir=^/proc | mail -s "clamav scan report XYSERVER" xy@mail.com the following errors appeared:
I compiled my kernel, compiled scsi support into kernel, used the new kernel and initrd, the boot failed.Then ,i unzip my initrd, found that sd_mod.ko can't be insert, i added it manual, and reboot OK.so, why! in the kernel configure , the sd_mod.ko is set to <M> , but why it can't be found in initrd?

(I can't replace old SCSI disk because it isn't available any more.) I disabled SCSI controler in BIOS and removed Adaptec SCSI RAID 2000S PCI card. I inserted PCI SATA controler connected both SATA disks and configured mirroring.
I'm trying to get Virtualbox up an running. So I have added virtualbox in my repo and added the key, looks fine so far. but afeter downloading I get this:
VirtualBox-3.0.8_53138_rhel5-1.x86_64 Creating group 'vboxusers'. VM users must be member of that group! No precompiled module for this kernel found -- trying to build one. Messages emitted during module compilation will be logged to /var/log/vbox-install.log.
Compilation of the kernel module FAILED! VirtualBox will not start until this problem is fixed. Please consult /var/log/vbox-install.log to find out why the kernel module does not compile. Most probably the kernel sources are not found. Install them and execute /etc/init.d/vboxdrv setup as root.
I've been using Fedora 12 for about a month, and i'm very happy with it. Even tough, there's only one thing that worries me, and is giving me problems at the same time. I'm getting an error from: syslog@localhost that says: kernel:Uhhuh. NMI received for unknown reason b1 on CPU 0 kernel: Dazed and confused, but trying to continue. Kernel: seems to be a problem, likely on the PCI Bus

Whenever I try to install Xubuntu onto my really old computer (not this one), it goes to a screen that shows nothing except the Xubuntu logo and the name. After a bit, my monitor falls asleep, and I am unable to wake it back up.If I press enter while at this screen, it brings up the error message in the title. The same thing happens with all the options I try to press.

I recently installed Kubuntu 10.04 Lucid Lynx Desktop 64-bit edition. The install worked and I was able to restart the machine no problems. Last week (5/27/10) I shut down my machine and since then I cannot boot. I assume it's because of new software maybe a new kernel; I did an "apt-get update; apt-get upgrade" on May 28th or 27th. Upon booting if I hit Esc right away I see:
(process:325): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) [About 5 minutes passes then this next line prints] BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) Enter 'help' for a list of built-in commands. /bin/sh: can't access tty; job control turned off (initramfs) [this is some kind of shell...who can't see my harddrive]
I'm running an up-to-date Lucid Lynx, full encryption with LUKS on my Eee 1005HA. Since yesterday, after booting, the only "X" is can see is the mouse cursor above a console-like text, saying:
Code:
(process_290) GLib-WARNING **: getpwuid_(): failed due to unknown user id (0) init: ureadahead main process (410) terminated with status 5 fsck [clean, blah bla, check deferred, on battery]
[code]....
So, I googled for the getpwuid_r thing. I found a blog saying to install nscd (did so) and run it. But: To my inconvenience, after every booting, I have to switch to console 1, log in, run "sudo /etc/init.d/nscd restart" and then "sudo restart gdm".
Currently running 10.04. Just did some updates and when it finished rebooting it just doesn't work right. Whenever I click on my user name to enter my password it freezes for 3-5 seconds then the screen reloads. If I do Ctrl+Alt+F7 I get this error(the title of the thread). I have no earthly idea what this means but everything was working great until I did my updates just a couple hours ago. on??

Failed login attempts are logged to syslog with the user id or login id set to UNKNOWN_USER or UNSET.Anybody know if this is configurable. I would rather it just pass the actual id that the user used. Doesn't matter if it exist or not, just want to know if someone is guessing at user names and what those user names are
I've had a Centos 5.3 zimbra mailserver set up for about 3 months now.Every 7-10 days or so, the system will do a kernel panic and I've been putting off its resolution due to other matters.I'm now ready to look into it but I have two issues :
1) No logs.
So far, I've manually rebooted when a kernel panic occured and could look at the panic printout and write down relevant info. But since I wanted more info than I had written down, I went hunting in the logs for the kernel panic event (one happened earlier today) but, to my surprise, I noticed the system doesn't log the kernel panic at all. Kdump is currently disabled as I'd like to keep all available memory available to the system but I was under the impression it would log the kernel panic message regardless but would simply leave out more advanced diagnostic information.How would I make sure the kernel panic is logged so I can have more info about it ?
2) The actual panic.Here's a snippet of what's appearing when the kernel panics :
I've also seen f793bee4 instead of the highlighted part above but everything else is always the same from the times I've seen (as I haven't always had the chance to be around when a panic occured).I'm looking further into it at this point but early research seem to indicate this could be a memory issue. I'll run memtest next weekend to check that out (since I don't want to take the system offline for any length of time during office hours) but people here might have other theories based on what I've put up so far. The system has all of the latest patches and updates and is running only what I need as far as software goes (zimbra server + prerequisites, x + GNOME (not loaded on startup), firefox and vnc for windows RDP access). My system also uses a software RAID1 array (boot = md0 and / = md2 with swap files not being mirrored as there's no need to).
PS : In order to further troublehsoot by myself before posting here, I've tried to enable kdump to see if kdump is the culprit for the missing logs but I'm also having an issue with it. I'm getting a "No kdump initial ramdisk found" and "mkdumprd: failed to make kdump initrd" messages at startup. I'm thinking this might be because of my raid array ? I've found an old bug report regarding one of those error messages on centos 5.2 but it was supposedly fixed in the 30 version by RH and I'm using the latest one (56).
I would like to use the collision detection routine from the OPCODE library, newest version 1.3 ... There exist documentations, e.g. Opcode.pdf and OpcodeUserManual.pdf, but they do not agree with the source code, neither the current nor the previous version 1.2.
Any working example to check if to meshes collide? I only would like to define the meshes using triangles and connectivities (no callback function). I started with a code like the following, but not successfully.
#include <Opcode.h> using namespace Opcode; int main(void) { IceMaths::IndexedTriangle *Tri0 = new IceMaths::IndexedTriangle[10]; IceMaths::Point *Pnt0 = new IceMaths::Point[10]; MeshInterface Mesh0;
I just isntalled LAMP using tasksel and have a problem. Whenever I try to access a page (aside from phpmyadmin, that works well), I get this error... Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0
I have restarted the computer, restarted apache, etc and still nothing. When I first installed, phpmyadmin was inaccessible, so I ran some command in terminal which apparently created a symlink between phpmyadmin in the user/share dir to the /var/www dir, and curious if this is the problem. I have no clue how to remove this symlink if this is the case, and have phpmyadmin working now due to install using sudo apt-get install phpmyadmin.
I am working with linux special edition LXFS Installed everything from the disk, works all fine but sometimes Linux shuts down suddenly and the following message appeals on a black screen. ' (proces 271) GLIB - warning getpwuid_r() : failed due to unknown uster id co) ' When I restart the computer everything is OK again. but than later it happens again.
"(process:325): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)"
It comes after choosing language, when the Ubuntu start-up logo shows with the 5 dut under it. I am trying to install Ubuntu Netbook on a little Compaq Mini.
When i try to install Ubuntu 11.04 or try without installing i get graphics like this:[URL] same with older versions, and on older versions i used to get this error: (process:257):GLib-Warning**:getpwuid_r():failed due to unknown user id(0) but on new version it dosent appear. My graphics card is: GeForce 7600GT MSI.
I used make-kpkg to generate bzImage from 2.6.39-3-686. After update-grub and booting the new vmlinuz system. I get:
"kernel panic - not syncing: VFS: unable to mount root fs on unknown block(0,0)". grub.cfg shows new entry 'linux/boot/vmlinuz-2.6.39.3-686 root=/dev/sda1 ro quiet' but previous working shows 'linux/boot/vmlinuz-2.6.32-5-686 root=UUID=210a363d-c0ed-4005-b6e8-bbc aeb7abe54 ro quiet'
Am I missing a step? (or two?). Is it possible to do this from 2.6.32? Currently running Debian-6.0.2.1-i386-DVD-1, Squeeze, /release/current/ 20110626-15:45 on a SATA 1T hd.
I just installed the DVD iso of Fedora 13...and did a "sudo yum update" after the installation got finished. After 3 hours of waiting, I restarted. I was greeted by Fedora with a kernel panic, right after it boots up.
Here's the message:
Code:
Kernel Panic - not syncing: VFS unable to mount root fs on unknown-block (0,0)
EDIT: Here's the content of grub.conf
Code:
# grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that
[code]....
What is peculiar on this grub.conf, is that the 2.6.33.6-147 boot conf is missing an initrd line...I looked in the /boot directory...and I found out that the initramfs file that matches the 2.6.33.3-147 kernel is also missing (i.e initramfs-2.6.33.3-147.fc13.i686.PAE.img).
My Fedora 14 box is no longer starting. I am getting a message at startup - "Kernel panic - not syncing:
VFS: Unable to mount root fs on unknown-block(0,0)".
Unfortunately, I don't know what I did before I got the message. I mean, I have made various installations, including some kernel drivers (such as a wifi card and a sound card). Also I did need to update the kernel-devel package as a requirement for some install or other. I know that is not very helpful, but let's get to the important bit...
What does the message "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" mean? What has broken?
And how does on recover from it? I have been reading around, and of course I am able to boot the machine from a live CD, but I am not sure what I should do with grub.conf, what I should rebuild, how to do it and so on.
I'm using Ubuntu 9.10 through Windows 7 and got this message today...
kernel panic- not syncing VFS: unable to mount root fs on unknown block (8,1)
Is there a way to fix this? (and I'm going to need really simple instructions here)
Also I tried to uninstall ubuntu in windows 7 and then reinstall but it will not let me. it says that an error has occurred: The system cannot find the file specified stdout=
