General :: Kernel(s) Will Not Boot Or Output Anything?
Jan 21, 2011
when I was updating my Ubuntu, the Linux kernel images were also updated (to 2.6.35-x), and the one I was using was removed (2.6.32-x). Since then, none of the 2.6.35-x kernels boot at all. I have upgraded several times, and now have installed 2.6.35-23-generic and 2.6.35-24-generic. Neither boots. I am running 2.6.32-24-generic, but there are no sources or headers for that. I even compiled 2.6.35-7 and 2.6.36, but neither worked either.
After I select the kernel in Grub, the screen goes blank, my hard drive spins a few times, and the screen stays blank, until finally the computer just shuts off. I tried running one of those kernels, and then booting normally after that failed, and looked at /var/log/kern.log. I saw messages from the last time I booted using 2.6.32-24-generic, and messages from when I booted just now (identified by the timestamps), but I could see no messages that took place in between, when the nonfunctional kernel should have been loading.
I really don't know what other information to add. I am running Ubuntu 10.10 on a Toshiba Satellite A215-S7411. The hard drive is an external hard drive connected with a USB Y cable. like VirtualBox, do not run without having the drivers compiled, and to compile them, I need the kernel headers, which I don't have and are not available in the repositories.

this is what i did i downloaded the latest stable kernel archive from kernel.org and extracted the archive into the download directory (i don't think that matters though) then i downloaded and installed the ncurses archive (needed for menuconfig) then i opened a terminal and navigated to the directory that was extracted from the archive and issues the floowing commands

I have a home-brewed Linux system that I've installed on a USB key. I'm plugging this into a laptop. I can tell from what is going on that it has successfully loaded the kernel and is running the shell script that is specified on the "kernel"he GRUB configuration.But... although I can get output from printk() calls in the kernel just fine, I get nothing from "echo" commands (or any other commands) in the initialization shell script. I can see that the commands are being run,t the output is just disappearing into the void.This is problematic because there are other problems, but I can't get debug output to track those down...Given that printk() output goes to the laptop screen as expected, it seems that GRUB must be sending other output to something other than the console, yet the grub.conf configuration is quite simple:
default=0
timeout=0

I've been trying to build and install a 2.6.37 kernel on a RedHat Enterprise 5.4 system. The build completes with no errors and I get the bzImage file as expected. I used /sbin/installkernel to install the new kernel on my system.
When I attempt to boot the new kernel it fails. RedHat nash starts and a few seconds later it panics with the message:
I checked the file that /sbin/installkernel named /boot/vmlinuz-2.6.37 and it shows that it is a "Linux kernel x86 boot executable".
The 2.6.18 kernel I'm trying to replace shows its filetype as "ELF 64-bit shared object"
There is a file in my build tree arch/x86/boot/compressed/vmlinux that is filetype "ELF 64-bit executable" which is closer. I test-installed this but GRUB said that this was an unsupported filetype.

I am using FC12 (2.6.31.5-127.fc12.x86_64) and I have tried compiling the new kernel, downloaded the sources from the kernel.org for X86_64. The kernel version is 2.6.32.15. I have successfully solved the mkinitrd issue referring to the tutorial on the howtoforge.net but still not able to boot into the newly compiled kernel. I have updated menu.lst,set default=0 to boot into the new kernel. Can I compiled my old kernel 2.6.31.5-127.fc12.x86_64? I don't have source code installed that is bugging me while writing kernel modules?

I usually have something like
iptables -A OUTPUT -p tcp --dport 113 -j REJECT --reject-with tcp-reset
in my firewall near the top, as I dont want the servers to generate ident requests and I don't want services (mail and ftp...) stalling when waiting for ident replies on clients with ident port filtered. This worked fine until the 164 kernel series.
Tested both 2.6.18-164.2.1.el5 and 2.6.18-164.6.1.el5. The rule gets matched, but the rst is never returned to the application so it stalls in every case. Booted back to 2.6.18-128.1.10.el5 and it works like a charm. I see no netfilter related patches in the 164 series that weren't present in 128.

I am using Ubuntu 9.10. Since a few days my I cannot boot anymore with the newest kernel (2.6.31-20.31). Instead I get a menu with a menu that lets me boot in recovery mode or boot from previous kernels (2.6.31-19).
In recovery mode for 2.6.31.20 it hangs at: Waiting for root file system. It boots just fine with kernel 2.6.31.19 except that apache and cups have to be reinstalled after every reboot. Everthing else seems to work without any problem.
Is there a way to do a system recovery, like in Win XP, going back to a system state from before the problems started?

I'm back with more trouble. The new kernel (2.6.38) won't seem to boot on my laptop. It would only do the initial reboot, then it wouldn't boot again. It started when I upgraded to Ubuntu 11.04. I tried a new install, that wouldn't boot. Then I tried Linux Mint 11, same problem. I have CDs for previous versions, in case nothing seems to work. What should I do to get the kernel to work. (I'm dualbooting with Windows 7)

I installed a fedora with kernel 2.6.15-1 (quite old, isn't it ?) on my vmware workstation and try to compile a new kernel with 2.6.15.2 just for testing. I download the kernel and compile with that:make menuconfig make modules-install install
then I reboot the server but if i choose the new kernel. the system poped up the error msg like : Unable to find device-mapper major/Minor No volume groups found unable to find volume group "VolGroup00"
Unable to access resume devices (/dev/VolGroup00/Logvol01)mount: could not find filesystem '/dev/root'
yes. I am using LVM to setup the fedora.
i search online and find some possible causes:
1) the .config does not contain support for LVM.
then i choose to enclude the support for LVM
2) need to re-create initrd i use commond initrd --force-lvm-probe to generate the .img file
But both the method do not work. and i notices that the new '2.6.15.2.img' is about 1.5M which is smaller than the current 2.6.15.1 img (1.7M)

I would like to boot the Linux kernel alone and run busybox, not including a GUI.
How can I do that? How can I make a custom bzImage, initrd.img and how can I change the file structures in that images?

I'm trying to upgrad from kernel 2.6.32.9 to 2.6.34.3 and I'm having problems.The boot finished with that old gem "Kernel panic - not syncing: Attempting to kill init !"I suspect that it's something to do with my PATA IDE driver because there have been kernel changes in this area.My problem is all the boot messages scroll off the top of the screen before I can read them and it's no use saying look at dmesg or /var/log/messages because the root fs isn't there - another reason why I think it's to do with the drivers.So my question is, is there some way I can slow down the boot process so that I have a chance of reading the messages ?

I have installed Linux Mint 9 within Win XP and have installed an additional HDD as a Slave on the same IDE cable as my DVD drive. I installed ubuntu on to the additional HDD using the live CD and when I try to boot the computer I am greeted by two versions of GRUB?! First version appears to be the one that comes with Mint and so asks me to boot either Windows or Mint, when I select Mint I get ubuntu's version of Grub, it asks me to boot one of three OS's; here's where it gets weird:
Top of screen says:
GNU GRUB Version 1.98-1ubuntu5-1mint2
If I select Win, it boots fine. If I select Mint it boots fine however if I select Ubuntu it says:
error: no such device
error: file not found
error: you need to load the kernel first
I pressed "e" within grub and was faced with this:
insmod ntfs
set root ='(hd1,1)'
search --no floppy --fs-uuid --set f6422203421e479
loopback loop0 /linuxmint/disks/root.disk
setroot =(loop0)
linux /boot/vmlinuz-2.6.3-21-generic root =dev/sdb1 loop=/linuxmint/disks/root.disk ro quiet splash
initrd/boot/initrd.img-2.6.32-21-generic

I am running a headless Ubuntu 10.04 server with the 2.6.32-28-generic kernel. For what I can figure out no single direct cause I get a high load average and the following syslog output at random intervals. Generally the load average will drop back down to normal however the kernel errors will still continue What little I have been able to find has pointed to memory issues. I am not totaly convinced this is the cause as the server will be showing >50% free when the errors are happening.

I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?

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.
grub.conf:

I installed a fresh copy of Slackware 13.1 (stable) on one of my media servers and I am experiencing something strange.... When I power up the machine, I see the kernel booting, no errors, until it gets to the point where it says:
And then randomly freeze there.... Well the machine is not totally frozen because the cursor still blinks. But it will never continue... Like I said, this happens on a random basis... After a reset, it might go through or simply stall at the same spot.
I remember after installing Slack 13.1, I rebooted the machine but forgot to remove the DVD from the player, so the install routine started up, and froze at the same point when it was loading the kernel for the setup programs...
My mobo is a MSI k9N platinum.
I never had this problem before.... (well I never used 13.1 before). Since I got this machine, I used slack 12.2 and slack 13-current with success.
This problem makes the machine extremely unreliable because I intent to use it as a backup and media server, so chances I will WOL the machine and use it remotely... if that happens.

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
[code]....
I can't see anything wrong and I did not change/try anything.

I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).
The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.
I am looking for a way to configure grub to remember its default boot item under kernel updates.

I'm guessing the answer to my question is in manipulating the kernel command line. But with what arguments? (and does the kernel have it's own fonts to be used on a FB device?)
The host is a ARM9 based embedded system with a 1-bit LCD screen.

I have an issue that is fixed by changing the lpfc driver to run using MSI interrupts. This is done by adding "options lpfc lpfc_use_msi=2" /etc/modprobe.conf.local file.
Is there a way to make this change using kernel boot parameters?
