Ubuntu :: Unable To Boot After Latest Kernal Update?
Jun 6, 2010
I'm a linux newbie so be gentle please. I'm on Lucid Lynx. Last night, the update manager installed updates to the linux kernel header. I'm not exactly sure what that means but it was one of the more important updates as it required a reboot.
This morning, my machine would not boot. After getting past the loading screen, my laptop hangs on a black screen. It was working flawlessly before yesterday. I can boot into recovery mode which appears identical to the regular mode, which works fine and is what I've been using. Also, I used a custom bootscreen, but it seems to have reverted to the default one that comes with the Lucid Lynx install.
After I upgraded from 9.10, I restarted and waited. ubuntu boot screen froze after a little bit, and the my caplock and scrolllock started flashing (I believe this is the kernel panicking) Then I tried safe mode and it did the same thing when is was saying something about sensors. So I then went to grub and started it with an old kernel and it booted fine (without the splash screen though) what should I do?
EDIT: ok the kernel version it is not working with is version 2.6.32-21 and it does work in 2.6.31-21. Also, it now doesn't say anything about sensors. It panics after App-armor loads ans skips Firefox's profile (or something like that)
Last week I could burn dvd's and cd's and had no problem. I did the latest kernal upgrade for Ubuntu 10.04 yesterday and today I cannot get K3B or Brasero to recognize any type of medium weather blank or filled. Looked on the forum and there appears a bug in the kernal. Is there a workaround? If so how do I use it.
I'm running 10.10 on a Lenovo x200. I have been running, happily, with 10.10. Yesterday, the update manager installed:
PHP Code:
After this update I am unable to Suspend. The screen goes black, the harddisk spins, the moon blinks a couple of time and then I'm presented with the Lock Screen.
I have: Kernel Linux 2.6.35-25-generic-pae 3.6 Gib of Memory Availabe disk space of 75.6 GB
Just did an auto update. Among the list of things was an SSL update and now I can no longer connect to my MSN account in Pidgeon. I get an error "unable to validate certificate, the certificate for Omega.contacts.msn.com could not be validated. The certificate chain present is invalid."
On my ageing laptop with Intel IPW3945 wireless adapter which has always worked extremely well.... Fedora 13 with the latest NetworkManager. Seems that wireless speed has slowed to a crawl.
I did the latest update on the opensuse 11.4 other day and since then my USB drive is not mounting. initially I thought its gone because my son dropped on the floor. But then when I plugged it to Windows 7 machine it mounted then I plugged it into another Ubuntu 10.10 machine it mounted so I figured out the there is some issue in the latest update. I have all the VMs in this drive and my main laptop is with OpenSuse 11.4
It seems today's kernel update has given a few people some difficulty - but my symptoms seem pretty unique.
* I go through GRUB normally. I 'esc' out of plymouth, and watch my services start. I get message 'mdadm: No arrays found in config file'. Don't remember seeing this before, don't have any RAID devices.
* Next, my file-system gets re-mounted in read-write mode (don't know if this is normal or not). Then, my services begin to start-up. My last service is 'crond'. All services start normally. When it gets to 'crond' the [OK] status is never reported. Visually, the screen flickers a few times, stops, then nothing happens. I can type characters though, and they do show up.
* If I then shutdown my computer by pressing the power button, the shutdown procedure begins. 'crond' shuts down successfully (indicating it started just fine), and the computer goes down normally.
* I don't believe this is an NVIDIA issue. I rescue-moded and changed my XORG.conf to the basic VESA driver to eliminate this possibility.
* Worst of all -- No older kernels work now either. They behave in the same way. When I try to boot to other run-levels, no luck either. This tempts me to think the problem might be file-system related and the re-generation of grub.conf threw something off?
My system is a Gigabyte GA-P35-DQ6 with Radeon 5770. The system was rock solid and everything working fine until the latest update I applied 30 minutes ago. The system is stuck on the little circle icon before the login screen.
I'm not able to ssh or telnet to the machine to check the log files. I edited my grub.conf a while back and I don't seem to be able to call up the recovery kernel. I can read up on the grub options.
I have just installed the latest update for Ubuntu 10.04, however upon requested restart i now boot to a black screen. the boot sequence is system post, followed by the generic Purple UBUNTU loading screen, following that you just get a black screen.
I have a dual-boot system (Windows 7 and Ubuntu 10.04) both 64-bit running on an HP pavilion laptop. I installed this dual-boot system only a few months ago and have continually added some new packages and updates with very few problems. However, now something has happened that really baffles me --- An error in the bootup process that I have never seen before and one that I have been unable to solve.
The problem I had been doing some programming (in Python) and after having the laptop on for several hours, I did a graceful shut down. Then, the next morning I turned on my laptop and the following is what happened:
[Code]...
I have tried the recommendation in B. to use 'chkdsk /r' in Windows. This took about 3 hours and had no effect on the error message. I also had made backups using "Back in time" which I tried (at least some of the directories) but none of these recovered directories had any noticeable effect on the error. This seems to be some basic device mounting problem that for some reason occurs only with the latest release and was triggered by some unknown event
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.
loaded on my system. Version 2.6.30.5-43 hangs after the progress bar completes with messges labeled r8169 about the ehternet link status. Version 2.6.29.6-2317.2 boots just fine. How do I remove version 2.6.30.5-43 from the system?
I originally tried Ubuntu 9.10 via a windows installation through Wubi. I had a VERY complex problem with a "Kernal Panic" due to an update through update manager and my system would not run proficiently. I wanted to know if that bug was exclusive to Wubi installations or does it also exist with this method of installation. I'm not going to update ANYTHING until I know for sure.
So I just installed the new linux kernel ( version 26) . On reboot there is a kernel panic with something like not able to mount root fs on 0,0. The older kernel works fine though. And btw while installing the kernel it did complain about not sufficiant space in /boot. I have got this message earlier, so I removed one of the oldest kernels. and i recently there has been package failure during installation of other packages. And one last thing, i noted that during the removal of the older kernel, there were lines in the terminal suggesting that kernel-26 had not been configured properly, so it tried to configure kernel-25 which also apparently failed.
I'm using ubnutu 9.04 for Application developments. still last two days ago. my linux starts procesing goes slow down and thats why i restart my system. but i cant login to my system normally. its goes to kernal command prompt and reading some messages like given below.,
Reading apache2 server [OK] Reading -------------- [OK] (NOTE : ---- means some messages like above.)
After it shows login in way of command prompt i given my username & password its redirected shell command., then i again give some instructions like startx. Then the normal pages are all appear.
Anyone Could known that process how to rectify that issue asap.
IS it possibility to boot my system with login page normally...?
When booting, I can choose 2 from 2 options (ignoring recovery mode):
- Ubuntu, with Linux 2.6.32-22-generic - Ubuntu, with Linux 2.6.32-21-generic
(and then Windows Vista and Ubuntu 9.10 a couple of times) The newer version appeared with an update from Ubuntu a couple of days after installation. When booting from the first I get the following message:
Code:
Kernal panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) When booting from the second, Ubuntu loads without a problem.
As the title says i updated my system which then needed a reboot. I also installed Mixxx djing software to try it out. So i thought id just restart the system. Usually when i boot into my desktop wireless automatically can connect to my router but not this time, wired only for now... i know theres tons of wireless issue threads but some more experienced users will be able to get straight to the point and run through some diagnostics with me.
I've been using Ubuntu now for 4 years and apart from getting the wireless card working on this laptop it has worked perfectly until now. I just loaded the updates and now problems, after switching on and selecting Ubuntu the next screen gives options
2.6.31-20 generic 2.6.31-20 recovery mode down to 2.6.31-16 generic
if I hit return or let 20 load the next screen reads 1.414518 Kernal panic-not syncing :vfs : unable to mount root fs on unknown - block (8,2) Caps light starts flashing and only way out is to power down. If I select 20 recovery I get a screen full of info and then caps light flashing and only way out is the power button, if I select 19 it loads and works as normal. Is there a simple way to get it auto loading again as the rest of the family use this and are now Ubuntu converts and will not realise whats going on and will reluctantly load up windows.......
I've been having problems with the system ever since I replaced the motherboard. Moving slow and just generally acting 'wonky.' Well the other day I reached my frustration limit and wiped the HDD. Up to this point the HDD had been in 2 partitions, one for the DELL diagnostics and one for the OS, XP Pro.
I decided that I wanted to set up the system in a dual-boot during the rebuild so I created a two partitions using the Windows install. Partition one is the DELL Diagnostic partition, partition 2 is the XP Pro partition and partition 3 is to be the Linux partition. All seemed to go well with the Windows install. I got the OS up and running and got all the updates done and drivers installed.
I only have the one HDD in the system so I was going to have to make this dual-boot off of one HDD.
I had previously, within the past week or two, downloaded the .iso and created the disk for FC11.
I went through the install process and successfully installed Linux on the 3rd partition, or so I thought. When I attempted to boot into Linux I got the Kernal Panic error.
My grub file as it exists now is:
Code:
If I leave the file as is, I get the kernal panic error but the splash image works fine. If I try to change the 'splash image' and 'root' references from '(hd0,2),' then neither works.
I can boot into Windows XP from the setup as it is now.
I if I boot using my LoaS (FC 11 made at the same time as the images for the cds were downloaded) I can see the hdd and multiple partitions. There seems to be a 'boot' partion, the Linux OS partition, a swap partion, as well as the Dell and XP partions. Now I've tried changing the references in the grub file to reflect the different partitions, basically I've tried 2, 3, 4 and 5, everything but 0 (the dell diagnostics) and 1 (the XP Pro).
I've also re-wiped the HDD and started the whole process over from scratch, thinking maybe I'd hosed something up the first time, but being a firm believer in 'Always do what you've always done and you'll always get what you've always gotten,' and that one of the definitions of insanity it keep performing the same actions over and over and expect different results, I seem to be at impasse here.
I have 10.04 installed on my daughters Laptop. After running an update manager session, the system asked for a restart. After restarting the Laptop won't boot up. Get a black screen scrolling with lots of hex addresses then 3 unable to mount messages ( mounting to /dev /sys /prod ) then a no init found message, followed by entering a busybox shell session which leaves me at initramfs: I'm a newbie at this linux shell stuff and don't want to make it any worse by scrabbling along blindly! System is a dell Inspiron 1501, Ubuntu is installed on a clean formatted single partition.
today when i updated my ubuntu 9.10 it was about 44mb update and update manager was not able to download 13mb of files i clicked continue anyway. after that i shut down my pc and when i restarted it my old black and ordinary GRUB was gone and there was one with Debian symbol and blue background and everything and when i selected any OS ( i have 3 os 1 on my 80GB hard disk which is ubuntu and other 2 are debian and windows XP which are on 20GB hard disk) and it said
