Fedora :: Boot Failure After Kernel Update / Log In As Usual?
Jun 16, 2011
I upgraded the kernel of my machine with a yum update, and now it will not boot. I am running Fedora 14 on a 64 bit machine. I really really need it to boot. Help!
I did Ctrl+Alt+F2 and managed to log in. I have kernel x86_64 2.6.35.12-90.fc14 installed. How do I log in as usual? I never get to a login screen.

Since doing the update which included kernel "2.6.32.16-141 fc12-i686 PAE" I can no longer boot into my usual 1280x960 desktop. I can set it using NVidia settings but even though this offers to modify xorg.conf it fails to do so. I have tried running as root and it doesn't then give an error message but when I look at xorg. conf there is no section.showing any specific screen size. It worked ok before the update. In case it is relevant the video card is a Quadro FX1400 with KDE. Also the whole program seems rather unstable since the update.

Dual Boot: Fedora 12 and XP Dell 505I've had trouble with the latest kernel update.I updated a bunch of packages recently (including Xorg and kernel), and noticed a severe flickering after the update on my center monitor (Samsung T260 - the laptop display did not exhibit the flickering behavior). I backed out all the changes and started updating package by package. After I updated the kernel (again) I rebooted and here's where the fun part is -
I no longer get anything, except the cursor. No grub menu, no grub prompt. I rebooted and ran the rescue disk and followed the procedurery and point grub at the right boot partition - see here. However (obviously or I wouldn't be posting) that failed to work. I still get a blinking cursor and dead system on boot up.

After a kernel update ubuntu would not boot. So found this procedure using the live update cd. Update grub.cfg & delete everything down to but not including the first line that starts with 'menuentry' . Then boot works ok. A couple of weeks ago it started on my notebook. Is anyone @ hq listening & able to fix this problem permanently?

So I ran the update manager to install the latest kernel. It goes fine and was sitting at the restart prompt. I was playing minecraft and the entire system locked up - couldn't restart X or anything. Hard restart and I get a multitude of errors mostly dealing with not being able to find things in /dev/... It gives me a command line but I'm lost as to where to go from here to repair my system

even from a terminal it wouldn't update? Maybe because I put my bootsector as ro ?
I don't know here is the message:

I have just updated my kernel and immediately struck trouble. The kernel update is marked as security update.
When booting I get a multiple warnings " deprecated config file /etc/modprobe...", then "no root device found" followed by "boot has failed, sleeping forever"!Clearly something is amiss with this update, so figured the best thing might be to remove it and wait on a fix, but attempting to remove the kernel via the package manager would cause a whole lot of other packages to be removed as well.Instead, I edited grub.conf, commenting out all the kernel-2.6.34.7-63 lines, so that the default is now the previous kernel (2.6.34.7-61).

I was having problems performing an update yesterday that failed on dovecot dependancies and after a few tries I removed dovecote (it wasn't being used) from the installation and tried again. Everything seemed to be going OK then the update (about 160MB) hung and the screen went black a few times and I think then shutdown automatically. The PC then fails to reboot and displayes the message "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" I have tried to get the PC to boot with the super grub disc but without success (probably my in experience) I have also tried a suggestion from one of the forums to start the PC with a live CD and typed su -c 'grub-install /dev/sda at the terminal again without sucess. I have looked at the files with the live CD there are grub, menu and kernel files there (some are in lost + found, b ut don't know wheer these should be so have not changed anything.
Is there an easy way for the in-experienced to repair the boot process ?
The PC is a pentium 4 running Fedora 13
There is a 200MB boot partition formated as Ext3
and a 19GB partition formated as a LVM with Ext4
There is a CD drive but no DVD
Everything has worked OK for the past year through two online upgrades.

I was finally able to install Fedora 11 x64 after choosing to only install packages from the repository on the install DVD. Prior to that when I had chosen tio install from the default online repositories, the install itself failed with a Python exception ( see my other post ). Now, however, once I boot after the install I eventually receive a kernel panic message, and failure. The exact same thing happened with CentOS 5.3 x64 after a flawless install. So unless someone knows what might be going on I will assume that Fedore, Red hat, and offshoots for x64 bit systems are just not for me. I have been able to successfully install the latest Mandriva and SUSE x64 Linux distros so whatever Red Hat/Fedora has done just does not work on my system.

I was updating the kernel and left the computer to let it do its business. There was power failure and I don't know if the update completed or if it was in the middle of it. Now if I start the computer, it freezes up at the login screen. I tried to recover from grub, by selecting "Ubuntu, with Linux 2.6.32-21-generic (recovery mode)". There were no prompts for input after this. The recovery screen is not updating anything after:
[2.348886] EXT4-fs (sda1): INFO: recovery required on readonly filesystem
[2.349015] EXT4-fs (sda1): write access will be enabled during recovery
[2.577641] EXT4-fs (sda1): recovery complete
[2.578072] EXT4-fs (sda1): mounted filesystem with ordered data mode
Begin: Running /scripts/local-bottom ...
Done.
Done.
Begin: Running /scripts/init-bottom ...
Done.
When I come out of that screen (ctrl-alt-del), the problem repeats.

I am trying to become su in the terminal window. It asks for my password, I give my usual password and I get "authentication failure". I thought that my log in password works for the su as well?

I just updated my kernel to kernel-2.6.29.5-191.fc11.x86_64 on my x64 system, after I reboot my machine, the Fedora loading bar comes up and finishes but then no gui comes up. I attempt to issue commands at the hanging prompt that comes up but nothing happens. I can boot into my older kernel just fine but not the updated one.
What can I do?

The girlfriend did an update a few nights ago. Besides removing her NVidia drivers, it also installed kernel version 2.6.27.29-170.2.78.fc10.i686.
That kernel was causing problems. Now it won't boot at all. How do we remove that kernel altogether?
If we remove it, would simply doing another update from the previous (still working) kernel just try to reinstall that bad kernel?

I ran the update through yum (replicated results twice) and whenever I boot to the new kernel it either freezes on the F logo or screen goes black right after f logo. No commands work whatsoever (tried em all). I can boot to an older kernel (2.6.33.3-85.fc13.x86_64). the ones that fail are: 2.6.33.6-147.fc13.x86_64 and 2.6.33.6-147.2.4.fc13.x86_64.
The Fedora error system gave me a bug report I submitted, here's what I got:
Package: kernel
Latest Crash:Tue 03 Aug 2010 09:46:33 PM
Command: not_applicable
Reason: BUG: unable to handle kernel NULL pointer dereference at 00000000000005b8

After updating my kernel from 2.6.34.7-56.fc13.i686 to 2.6.34.7-61.fc13.i686 I can't boot anymore. The error message says: "No root device found Boot has failed, sleeping forever."
I'm booting from 2.6.34.7-56.fc13.i686 now but I would like to sort this thing out. What should I do? File a bug? I never did that, so I don't know where to go.

I have recently updated my Fedora 11 installation which replaced my older 167 kernel with the newer 217 kernel. However, the 217 kernel will not boot completely. It will show the splash loading screen, and then will switch to a rapidly blinking cursor. This cursor blinks for about 5 seconds and then disappears. I can access terminals using ALT+F2, etc. I can log in to these terminals, but init commands do not complete (something about a binary handler). I'm not sure if something is conflicting with an update to X or what is wrong. The most recent kernel that I managed to get to work was Kernel 167, however I cannot find this kernel for download.

AMD Athlon 64 X2 4800+
3GB RAM
nVidia GeForce 8600GT with proprietary drivers

I tried to update my f12 today. In the list it showed an update for kernel-2.6.31.6-145.fc12.x86_64 It all seemed to go OK but when I restated my computer it spit up an error and wouldn't boot"Could not load /lib/modules/2.6.31.6-145.f12.x86_64/modules.dep: No such file or directory"Luckily the old kernel still works.
I do have the disk encryption set, could this be related to that? Updated my laptop today with the xx.6-145.f12.PAE kernel and now it's borked to. Same problems.12/07/2009OK today's kernel update seemedto fix the problems and now all is well, execpt for my inkscape not working problem. But I put ubuntu 9.10 in a VBox and it works. So for now that's my work around.

I am unable to boot my Fedora 14 after last nights kernel update. When I start the boot up and hit F2 the system fails after outputting the line : Starting vservers of type 'default'. At some point the console displays an error message :
serial8250 : Too much work for irq17
How do I restore my previous version? I know some people have suggested in the past - just modify the grub.conf but how? When I boot off the cd I only get access to the liveuser disk. I need to have access to my own /boot/grub/grub.conf file.

I have just updated my kernel to version 2.6.38.8-35 in Fedora 15, it now refuses to boot that kernel. I just get a lot of text on the screen and nothing happens. I can ctrl-alt-fn to get to a prompt, but I do not know how to fix the nvidia problem.
When I edit Xorg.conf and replace 'nvidia' with 'nv' the new kernel boots but only to fallback mode, trying to then re-install the nvidia drivers shows them to be already installed and I can get no further.

Lately I'm encountering a somewhat annoying malfunction: almost every boot, my desktop is stuck, HD red led is constatnly on, and i get a message from kerneloops that I had a kernel failure. I can move the cursor a little and slowly or not at all. Few violent reboots and I get a clean boot. Running Debian Lenny kernel 2.6.26-2-686 on a Pentium 4 2.0 GHz with 250 MiB ram.

It appears that I have really messed up my machine. I was trying to get matlab working on FC 11 and I ran into libc.so.6 issues, so I put an older file libc.2.3.1.so in /lib/tls/ directory and created a symbolic link libc.so.6 to see if the application would work. Unfortunately at the same time the system did some updates and the system hung, so I ended up rebooting, but now it gets stuck at boot screen (after grub) with a kernel panic - not syncing: attempted to kill init.I just need a way to get to the directror /lib/tls and delete the link and the older .so file I threw in there. How do I get this accomplished. I cannot get even to a shell from the boot screen.

I have a problem with the kernel update to 2.6.34.6. Up until 2.6.33.x my system boots fine, but with this update the boot stops at the moment that the mouse cursor should become visible. To resolve the problem, I've gone back to 2.6.33.x and removed the 2.6.34 kernel but I wonder what happens with the next kernel update.
Anyone else having this problem?

I'm not sure what caused it, but it happened right after running 'yum update'. It may be because it installed a new kernel, and there are now two kernels listed in my grub.conf and at boot; 2.6.31 and 2.6.32. System boots through a list of things it's starting up and stalls out at ATL or ADL or ADM maybe. It hangs there for a minute or so then flickers. This happens every time at boot. It's a bit difficult to post more information since I can't get past that part of the boot process, and I can't seem to be able to skip it either. It may be worth mentioning that this is a mini-itx motherboard. Intel Atom 330 1.6, 2GB DDR2, onboard GeForce 9400m. It's a zotac ionitx-a-u. I've installed a fresh copy of Fedora 12 lxde.

Finally updates are broken - I've been able to use my upgraded F12 system for some time, faithfully keeping up with f10, then f11. Just yesterday it finally broke:
Test Transaction Errors: installing package kernel-2.6.31.12-174.2.22.fc12.i686 needs 10MB on the /boot filesystem
It would appear that the most recent kernel update has broken the 10MB barrier initially set by the version I first installed (for the boot partition). Needless to say, I have quite an investment in this machine, and of course no time to back it all up and do a fresh F12 install. I am hoping someone out there can give me a bulletproof way to steal some space and expand the boot partition...

I've been running Ubuntu 10.04 AMD64 on our home theater PC through a wubi installation. Yesterday the system update installed a new kernel and today there is a problem booting the computer so I'm reluctantly using Windoze to type this. there isn't much information: the computer has always booted fine before the kernel update. When I select Ubuntu in the boot menu the screen goes black and the computer restarts. No error messages, no GRUB menu, just a blank screen before restart.

How do I install an additional kernel in Linux Ubuntu 10.10, in case of a boot failure? Also how do I make the Grub Menu Visible, so that I am able to select multiple kernels. There is an older solution below, but is there a way to do this in Linux Ubuntu 10.10. I just suffered an update failure, possibly due to a corrupt kernel upgrade, which made my system unbootable. The cursor just flashed continuously.
Solution of 2007[URL].... "The next obvious rescue aid is to always have a working kernel installed. I usually work from a kernel updated via yum. Kernels have occasionally been released with flaws that have caused one or more of my machines to not boot. To this end, I always make sure I have at least one perfectly running kernel on a machine. A great way to handle this is to first add plugins=1 in your /etc/yum.conf file. The next step is to take this script (written by Jeremy Katz from Red Hat) and save it as n-installonly.py in /usr/lib/yum-plugins. You can change the number of kernels to retain on the system by changing the tookeep variable (default = 2).
With a known working kernel on your system, you can upgrade safely. If the new kernel is hosed, simply boot the old kernel to solve the issue with the new kernel be it to remove it, recompile it, or update it."

After performing the periodic update on 2010-05-26 including libc, libc6 and libgtk2.0 my system fails on boot with the following error message:
Code:
run-init: /sbin/init: no such file or directory
Kernel panic - not syncing: Attempted to kill init! If I boot from the 10.04 live CD, all partitions on the hard drive are visible, mountable, and pass all file system checks.
