I compiled a new kernel for slackware 13 yesterday and all is going well, except for the fact that during boot I get errors regarding a second hard drive. They are of the form
PHP Code:
[code]....
I wasn't getting this error with the previous 2.6.29.6 kernel. As far as I can tell everything is working fine, but the errors make me nervous as this is where all my data is stored. The partition was previously formatted ntfs-3g and I thought maybe I'd done something with ntfs support while configuring the kernel so I backed up the data, reformatted to ext4 which matches all other linux partitions except for swap of course, and I get the exact same errors.
1. Is there something different in this kernel in reporting errors or maybe something I set in configuration?
2. recommend a good (simple and ubiquitous) cli program to check the disk for errors so that I can run it in both the old and new slack kernels as well as mandriva on the same machine?
I have 2 hdds, with encrypted / and /home. Besides there are four other (encrypted ext4) partitions I use rarely. In Fedora 11 at boottime I gave the luks passphrase for / and home and the system booted as intended.
Whenever I needed those extra encrypted partitions I mounted them in Nautilus. Now, in Fedora 12 at boottime dracut tries to open all the encrypted partitions, / and /home are mounted fine, but opening all the other partitions gave the following messages in messages.log:
Quote:
dracut: luksOpen /dev/sdb6 luks-02a0e706-a26f-4019-a2a0-88a0366a994d kernel: Buffer I/O error on device dm-0, logical block 124 kernel: device-mapper: ioctl: unable to remove open device temporary-cryptsetup-304 kernel: Buffer I/O error on device dm-0, logical block 124 kernel: Buffer I/O error on device dm-0, logical block 124
[code]....
...and these messages are repeated with the other partiitions, and the boot time takes very, very long. How can I tell dracut to ignore those extra encrypted partitions at boottime?
I am trying to debug the issue of a desktop that has for the last two weeks started having kernel panics at boot time. This machine has been running flawlessly for the last 8 years, and has had three OS upgrades. I am using memtest to try to understand the issue. The following is part of the memtest output: Reading all physical volumes Buffer I/O error device hdc logical block 0 Buffer I/O error device hdc logical block 15

i have a inspiron 1520 laptop which is starting to slow down some so i thought linux would help because all i do is internet use, so i download it from another computer and mount it to a usb flash drive like the site says, (netbook remix latest version) then i put it in my laptop and it loads all the way and i press try and after about 10 minutes of loading it lets me try. so that was ok really slow but i thought id install it to hard drive to see if it improved speed. so the next time i start my laptop i get Buffer i/o error on device loop0 logical block xxxxxx so i redo the usbflashdrive no errors switch usb ports and same thing, ive done the switch usb ports and redo the flash drive about 4 times im really getting mad at linux before i even have it installed.
I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error: Memory for crash kernel (0x0 to 0x0) not within permissible range Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00) The failed "read 10" packet command was: Buffer I/O error on device hdd, logical block 176935
(This error message repeats for another 9 or 10 times then it says the following) Red Hat nash version 5.1.19.6 starting Setting up new root fs (Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).
Setting Clock Starting udev Loading default keymap (us) Setting hostname local host.localdomain Setting up logical volume management Checking file systems
These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.
Create symlink /dev/root and then exit this to continue the boot sequence.

loops that during install. new hard drive fresh out of box. WD 320GB 7200 Toshiba Qosmio intell core duo i've installed with this same disk before previous hard drive died. installed over windows vista. this time im trying to install solo no windows disk to reinstall with, F10 only. I've tried other distros as well, Mandriva one 2009, Dreamlinux, and this one. i've suspected hard drive controller went out but i can format and partition the drive. also the cd/dvd drive is bad but im booting from cd fine. tried removing the cd drive and booting from an external usb cd rom, same errors.
im about to deploy and need my computer up and running ASAP. 7 months no entertainment is not good. when i use a linux boot disk from Ultimate Boot Disk (UBD) i get an error of - hda status no response and something about invalid heads dreamlinux pushes past the error till i get the error about cant start x server. about my graphics
i've just burned a livecd (fedora 11), but it doesn't work correctly.it says after i hit boot:

and then something else, which is similar so i didn't write it down.i read on bugzilla, that is should try to append the boot command with pci=nomsi, but it doesn't work for me
The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.

I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.
I have been having a lot of trouble lately with installing from CD/DVD. The DVD reader/writer on this laptop is new. Nevertheless, trying to install Ubuntu onto an exernal HD, I get 'input output error on sr0 logical block (a large number) After a long time the booting proceeds to a point, but I never get the actual installation started, and have to shut down manually.
The CD is fine, says the Ubuntu-checker. I just installed using my sons laptop, and there was no trouble. Question: does this indicate a motherboard failure? A memory block damaged? Do you know of a diagnostic tool I can use to check the reading of a CD/DVD?
After fixing drive partition numbers, I got the following error from cfdisk: Code: FATAL ERROR: Bad logical partition 6: enlarged logical partitions overlap Press any key to exit cfdisk However, I can see all my partitions with fdisk and gparted, I can mount and use all of them.I used the following guide to fix the drive numbers order: Reorder partition drive numbers in linux | LinkedBits Does somebody know whet is cfdisks problem and how can I fix it?
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.
i am just learning about computers and know nothing at all except how to turn it on. i just booted up linux and recieved message: [0800654] Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown - block (8,1)
I add new syscall, and it need copy big data into the buffer specified in user mode. How can i do it? use copy_to_user? or can i use memcpy directly? If i use copy_to_use, is it low efficient?v
I need a shared buffer between user and kernel space. I read that one way is to allocated buffer in kernel and then call mmap from the user space. I searched for an example but couldn't find something useful. If you know, could you please send me any links or sample code that does this..
I have upgraded from 10.4 to 10.10, and when I restart I get the error "kernel panic - not syncing: VFS: unable to mount root fs on unknown block".I've done some googling and found this is a pretty common problem, but no existing solutions have worked for me.Right now I am using the 10.4 live CD.
I am trying to install debian on my windows PC but am receiving some errors with it. I have downloaded "debian-506-amd64-DVD-1.iso" from debian website and am seeing that the md5 sum is correct. I am getting following error when I choose Graphical Install or install.

I started installing the beta of Maverick a few days ago, but the update server was running inordinately slow, so I canceled it. Several times, I have attempted to continue the installation, but I've been unable to reach the server. Shortly after this happened, I could no longer boot normally--I get the error:
Code: Kernel Panic - not syncing:VFS:Unable to mount root fs on unknown-block(0,0) Choosing the previous kernel fixes the problem.
So, I obviously want to upgrade to the release version now. When I open the update manager, I get asked if I want to do a partial upgrade to complete the install. I'm a bit leery of doing this since I only have one previous kernel to go back to (my list got really long and I have another operating system entry underneath, so I set my automagic boot manager to only keep two), and if I can no longer boot after the upgrade, I'll have to use Windows until it gets fixed... So, should I finish the upgrade, try to troubleshoot the error, or do something else to jump right to the latest release, after being partway through the upgrade?
I have 250Gb, 500Gb and 1Tb drives concatenated together as one volume group (span) with a logical volume (spanvol). Under kernel 2.6.31.5-127.fc12.x86_64 it mounts totally fine. However, under 2.6.31.6-145.fc12.x86_64, I get this:-

When this appears the disk becomes unavailable and I have to remove and plug it in and mount again. After that it works couple of hour and then the problem appears again. Is this a hardware problem?
I am facing a problem while installing backtrack 4.0 on my virtual box. After assigning a hard drive and booting from the live cd, i am receiving a error message as follows:

It is not the first time i install operating systems on virtual box though it is the first time i receive such an error with backtrack.
