Red Hat / Fedora :: Error 8: Kernel Must Be Loaded Before Booting
Nov 16, 2010
I'm relatively new to Linux, and have broken many more things than I have fixed.. I guess that's the learning process eh? So here's my problem: I've been experimenting with the mount command, and have mounted my local file system (sda1) to a directory (/mnt/test). I was attempting to mount an external hard drive, and sda1 clearly was not the correct drive (I did eventually discover where the external was located, however sda1 remains tied to that directory). I rebooted my system, and now the Grub command prompt loads. When I type "boot" I'm presented with "Error 8: Kernel must be loaded before booting". I'm assuming this is because I mounted my local file system, but I could be wrong. Does anyone have any ideas how I could remedy this?

I Installed Fedora 14 about 2 weeks ago and was just settling into using it more or les permanantly and had to turn of the power to do some maintenanace. When I rebooted I got the grub> prompt. As I have already shut down and rebooted several times over the last couple of weeks, I could not se why this happened, so I rebooted and stiull got the same problem. Things I have tried:

I am currently using a 64 bit ASUS P75P55-M motherboard.

I just installed fedora 10 using the GUI install, and when I try to boot, it gets me to the grub command line
grub>
when i enter 'boot', it gives me grub error 8: kernel must be loaded before booting. Not sure how to fix this.
Also, I used to have fedora 9, and i had an option to boot fedora or 'other', which is windows. How do I go about setting up something similar in this case?
EDIT:
Also, when I type root, it tells me that the partition (hd2,0) (i assume the one i installed FC10: 3rd hdd, first partition) is an unspecified file system ...
I think something happened to grub when it removed my old partition with FC9...

I've been looking forward to making the switch to Ubuntu for a while, but ever since I did, the road's been pockmarked with errors and hassles. That's, primarily, because I don't know what the hell I'm doing. Let me explain how I installed Ubuntu: All I did to install Ubuntu was download the file from the website and run the program. I didn't burn anything onto a CD or USB; I just clicked on the .exe file and let it run from there. Everything worked great - all I had to do was boot my laptop and choose from either Windows 7 or Ubuntu. Now, I had no idea how to watch videos, so I started to install a lot of stuff from the Synaptic Download Manager. Now, I don't know all of what I downloaded, but it was mainly games. The next thing I know, I get this page when I choose Ubuntu:
Code:
GNU GRUB version 1.97~beta4
[minimal BASH-like line editing is supported. For the first word, TAB lists possible command completion. Anywhere else TAB lists possible device/file completions.]
sh:grub> _
So I hit TAB and try the easiest command on the list, BOOT. This is what I get when I try boot:
Code:
error: no loaded kernel
So I don't know what I did wrong.

I was about to do upgrade from 11.3 to 11.4.I was following the guide I found in opensuse's website. I was to the point where I had to disable all 11.3 repositories and add the 11.4 at that point I forgot to change my nvidia repository ( I have a g210m graphic card).
thus after the upgrade the X could not start at all. I think this was because Yast could not find the nvidia driver.
Using text mode YaSt2 I added the nvidia driver but after restart I can not see and X running. I receive an error message that the current kernel can not be loaded!!!
I also checked in command line if there is something like Sax2.. but I couldnot find anything.

I used to have FC11 installed with the nvidia supplied binary driver. Worked fine, very stable. Trying FC12 and FC13 live CDs caused a hang, so I stuck with FC11. FC14 live CD did boot so I backed up my own files and did a clean FC14 install. Upgraded to get kernel 2.6.35.6-48, installed the nvidia driver from RPMFusion (260.19.21) and had a working system! Now, after a cold boot, the kernel always hangs during boot. Tried a number of kernel boot option (apci=off, noapic and a few others too). The hang is not always at the same place. The earliest it has hung is after:Disabling lock debugging due to kernel taint
Sometimes its a few lines later at:NVRM: loading NVIDIA UNIX x86_64 Kernel Module 260.19.12 ...(which would seem to imply that the hang can even occur a step or two before the actual driver is loaded!)
Sometimes it keeps going for a few more seconds and randomly hangs during some other driver load.
Without a specific nvidia driver the system always boots ok, so I'm pretty sure its the nvidia driver but I just can't seem to get a handle on this in a reproducible way. Sometimes, when I have make some other change, it will boot and work ok, but a reboot locks it up again (for example, in case it was SELinux, I disabled it and on the next reboot it booted and worked ok. Then, next boot, it wasn't working again). When I make changes, I reboot using the previous kernel, make the changes and reboot, with an occasional success. Once I start rebooting using the latest kernel, it always hangs.
I'd love to get a solution to this, but even some advice on debugging this would be appreciated!
I'm using 8600GT, 256Mb, PCIe card in a MA69VM motherboard with 3Gb of RAM.

These days, I tried to compile my own kernel. Now, it seems work. However, when the kernel is booting, I always get the error message like below:
acpiphp_ibm: ibm_acpiphp_init: acpi_walk_namespace failed
It looks that something is wrong with my acpi subsystem's configuration. But no matter How I reconfig it, this message still occurs.
My distribution is UBUNTU 10.04 LTS
original kernel with the distribution is 2.6.32
My own kernel is 2.6.35

After a reboot, my PC just hang. It says "insmod : error inserting '/lib/raid456.ko : -1 File exists ..." then followed by a kernel panic. I have tried to boot using rescue mode but it couldn't find any Linux partition, thus no /mnt/sysimage was mounted. It left me at a shell and I'm stuck there.

I've been playing around with trying to assemble a bare-bones Linux system on a disk.img file through a loop device. I compiled the most recent stable kernel and then copied it onto the root partition in the image. When I try to boot up into the image using qemu, grub gives me this:
Code:
Booting 'tiny'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinux
Error 13: Invalid or unsupported executable format
Press any key to continue... I am confused because I compiled the kernel with 'make bzImage', and the architecture hasn't changed (qemu on the same machine used to build the kernel). So it should be bzImage format. Is that what this Error 13 means, or could it means something else is wrong...?

I'm trying to get Ubuntu 10.04 running on a PCM-9343 board from Advantech. To do so I followed the instructions in this file from DM&P [URL] I installed a text-only Ubuntu using the alternate installer on a CF card that was connected to my PC. After reboot I downloaded the given kernel and updated the installation on the card, as said in the instructions. Inserting the card into the PCM-9343 gives a working Ubuntu Installation. So far so good.
The only thing not working is networking. The ethernet adapter is not loaded on boot, neither can I up it after logging in using "ifup -a". I found out, that the driver was not loaded during booting, i.e. the module r6040 didn't show up on "lsmod". The module is included in the modified kernel, that I downloaded from the producer's page. So I added it to /etc/modules and rebooted. Now it's loaded, but still no eth0. Ifup -a gives the following messages:

The graphics card on a openSUSE11.4-32-bit system is a ATI RV530LE [Radeon X1650 PRO] It looks as though xorg sets it up with the RV535 or RV560 chipset if the radeonhd driver is selected Is there a way to ensure the RV530 chipset version is loaded when booting.

I had fedora-11 installed and the kernel version was 2.6.29 I downloaded new kernel version 2.6.33.2 and did following,
make mrproper
make
make modules_install
make install
when I rebooted and selected 2.6.33.2 from grub entry, fedora logo came and spalshed, after that monitor started blinking and now its not going anywhere, i can see blank screen and nothing else. If I do ctrl+alt+del it shuts down the system normally.
I tried interactive mode also system did fine untill this point "registering binary handler for windows application" after that the same problem came, monitor started blinking and screen is blank., Any pointer regarding this will be helpful , what exactly went wrong? I can provide more info if u need it.

I installed VirtualBox-OSE and VirtualBox-Kernel from the Slackbuilds at slackbuilds.org.When I start VirtualBox I get the following message on the CLI: Code: WARNING: The vboxdrv kernel module is not loaded.Either there is no module available for the current kernel (2.6.33.4-smp) or it failed to load.Please recompile the kernel module and install it by sudo /etc/init.d/vboxdrv setup.You will not be able to start VMs until this problem is fixed.I gave /etc/rc.d/rc.vboxdrv executable permissions, and then ran.The only issue is, I have to do this each time that I reboot, should I add 'modprobe vboxdrv' to one of the startup scripts or is something else wrong?

I have a zyxel dsl (usb) moden, which needs a firmware portion to work, called cxacru-fw.bin.
I have been using this modem using with at least two different slackware distributions, even when the atm drivers were not included in the kernel.
Presently I am using slackware 13.0, with the vmlinuz-huge-smp-2.6.29.6-smp kernel.
I downlowded the 2.6.34 kernel, because I need it for a new webcam, compiled and installed it, and oops! the modem does not work anymore.
I am pretty sure I have configured the kernel correctly; dmesg tells me the modem is recognized by the kernel, as it is with the previous one, but the firmware is not loaded, because the DSL led remains off.
I attach the kernel configuration lines:
I have tried forcing the kernel to load the firmware, using but it didn't work either.

In an attempt to ameliorate some other problems (lm_sensors, and loopback), and based on several forum entries, I decided to update the default f15 kernel (2.6.38.35) using kernel-2.6.39-1.fc16.x86_64.rpm from rawhide. It seemed to install without problems and when I rebooted it seemed to hang just before completing the boot process. The on screen boot messages ended with:
Started Display Manager
Started LSB: daemon for libvirt ........
Starting LSB: suspend/resume libvirt guests on shutdown/boot
[ 12 ......
about a dozen similar lines ending with
[25.030991 hci_cmd_timer: hci0 command tx timeout
then it apparently hangs
However, at that point I can log into to a console using Cntl-Alt-f2, so most, if not all, the crucial boot processes seem to have completed. There is an issue with the nVidia driver that I will deal with by modifying /boot/grub/grub.conf to re-enable nouveau, but I am stumped by what is causing the hang up. There is a certain amount of traffic regarding a similar problem with Ubuntu 11.04, but no solution other than it seems to be related to a BIOS bug (NFI)
what sub-system uses the "hci_cmd_timer" and why it might interfere with the boot process? Has anyone else run into a similar problem with f15?
Is there a better way to get an updated kernel in f15? I do want to keep all the Red Hat patches and back ports, so reluctant to build a kernel from scratch from upstream sources at kernel.org (and maybe just a bit apprehensive ;-})
