Ubuntu Installation :: Newer Kernel Updates AFTER 2.6.32-17 Has A Randomness At Boot Time Whether The System Will Completely Boot Or Not?
Jul 26, 2010
I've been having a problem on my AMD based machine, 4cpu, gigabyte ga-ma78gm-s2h Mobo, 8GB mem, two 2 terabyte Sata HDs.One thing I've found is that any kernel after 2.6.32-17 has a randomness at boot time whether the system will completely boot or not.
For instance just today I downloaded and installed 2.6.32-24
It fails to boot (I've tried cold boot, warm boot).Running its repair also fails to completely boot.My experience is that if I keep trying it "may" eventually boot but I believe there was some change after 2.6.32-17-generic that's causing the problem.Because as with 2.6.32.23... which also fails to complete bootup many times... eventually my guess is that 2.6.32.24 will also boot "sometimes".But why does 2.6.32.17 always boot for me? Something changed and its not my setup.

I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).
However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.
Question: Why haven't the newer updates shown up in GRUB for booting purposes?
Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?
How can this be changed? The new kernels do not show up in Start-Up Manager either.

I have installed ubuntu 10.04 64 bit in April and it has worked flawlessly. However, today I ws prompted to install Kernel updates. Now when I try to boot it continually cycles between a black screen and the NVIDIA logo.
Yes I have been using the nvidia drivers previously but without incident till now.
I have tried crtl-alt-f1 but this does not stop the cycling.

I'm a very new Linux user, so speak slowly and don't use big words. I installed Karmic from the Live CD. It is the only OS in use on this system. I then upgraded to Ubuntu Studio using the instructions found on the wiki.
On bootup, I get a brief message stating "GRUB loading" and then the system automatically boots to the generic kernel. No GRUB menu is ever displayed. I would like the option to boot to the real-time kernel, but I have no idea how to edit the appropriate files. I've done a fair amount of reading on the subject, but I find very little information relating directly to the real-time kernel, and so I still feel like I'm too green to do it without messing something up.

I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?

When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.

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.

Possible Duplicate:Make grub keep its default boot under kernel updates.I have just installed Linux with my windows 7 pre-installed and i got it working fine. Since i use windows 7 more than linux, i would like to have "Windows 7" option on the top of "Linux" option.
"When i have turn on my computer, the first thing i see is an Option asking me whether i want to use windows 7 or Linux and there's a countdown timer below it which is 10seconds countdown and if i don't select it on time, it will automatically select the first choice which at the moment i've got Linux pre-set as my first choice."

I recently Installed Ubuntu 11.04 on my Compaq evo n800c
CPU-Pentium 4
RAM-1GB
HDD-60GB (yeah i know, it's old)
GPU-ATi Radeon Mobility 7500
Installation went fine but when I boot in Ubuntu I get a MS-DOS like workspace that asks for my login and password. When I give it my credentials,it just says welcome in text and thats it. Now if I go into recovery mode and choose any of the options [normal boot/failsafe-graphics boot] the screen goes completely white. I spent hours searching Google for a solution but nothing worked. what is the problem and also what will be the solution for it.

I did a yum update to install quite a few updates to my Centos 5.3 x86_64 system. Updates included kernel and xen which required a reboot. It must be a month or so since I last updated. The updates seemed to go fine - but when the machine restarts it goes through the bios screens which seem to detect all the hard drives etc - but then the word "Grub" appears at the bottom of the bios screen - and the system hangs. It doesn't appear to respond to keyboard input. The system is using linux raid in case that is relevant.
I am able to boot a centos5.2 live CD and look at the Logical volumes - and all appears in order to my untrained eye. I have also mounted the /dev/mdo as /tmp/bootx (boot volume) and had a quick look at /tmp/bootx/grub/grub.conf and /tmp/bootx/grub/device.map and again - I can't spot any obvious problem. I note that before the updates - my default boot was "1" and now it is "0" though this appears reasonable because the xen and non-xen images seem to be listed in the opposite order to earlier updates. I have set it to boot non-xen by default - and this has always worked in the past.
I realise that the recent updates may be a coincidence - and whatever is wrong may have occurred earlier. I cannot think of anything I have done which could have broken grub though. I can probably restore my boot volume to the state it was before the updates. I should have a backup from this morning - as luck would have it. Is this a safe thing to do - or do I need to restore both boot and root to keep them consistent. I would prefer not to restore the root system unless I have to - as this would cause some data loss. However I need advice as to whether yum and other things will get confused if the boot volume is restored in isolation.

i used dual boot system (xp + ubuntu 10.04) and decided to replace them with jolicloud os and then it started In about 86% of jolicloud install it showed me error of hdd partition. I tried different versions of partion type, used also option to install on entire hdd - none of my tries actually worked (also with many hdd formating tries) so I was able to use only usb as live user for Jolicloud, and i burned ubuntu iso on disk - on boot up showed boot up error, i checked BIOS and everything seemed to be ok with boot order. So after many tries i took my old Gutsy Gibon 7.10 live cd. I first updated it with LTS version (8.04 Hardy Heron) and after that I updated it to 10.04 but it seemed to not finish when i saw some error in terminal and installer was exiting 13 minutes before finish then it had kernel panic - fuuuuck! After that i tried to download small versions of linux like Austrumi and puppy linux , but it showed me boot error or cd didnt even open install dialog without showing boot error.

We have 2 applications set as S96 and S98 at rc3.d and rc5.d simultaneously. Both applications create a system V shared memory segment by calling shmget.If the system boot at runlevel 5, both applications can obtain their shared memory segment id correctly, i.e. 98305 and 131074 individually. While there is a root owned segment id 32768 takes first seat on the list. This is the id list:
root, 32768
S96_app, 98305
S98_app, 131074

I installed Ubuntu over my windows partition but kept the other NTFS partitions that I use for storage. For some reason GRUB shows up with the option to boot into XP (which isn't there). How do I get rid of the boot menu completely so my computer boots straight into Ubuntu?

Installed ubuntu 10.4 over previous ubuntu on Intel 945G. After installation and reboot the system does not boot: "no bootable device - insert boot disk and press any key".
Installation was done from USB-stick, prepared by UNETBOOTin. I have two HD's, one used for system + storage, another one just for storage. I manually deleted previous system partitions of previous ubuntu install in system HD. The system HD had about 1/3 of free and unallocated space for system partitions, which ubuntu installer created during the installation.
I tried to reinstall grub from bootable USB-stick and it succeeded but it did not help. The system is still not bootable.
I have used ubuntu for years and never happened something like this. Am I missing something or is ubuntu missing something???
HW failure is ofcourse possible but I am quite skeptical about it because Live ubuntu from USB-stick works well.

When I first installed Ubuntu as a dual-boot (about 18 months ago), I had problems booting to XP, which were eventually solved for me in this thread, which set Windows to boot Ubuntu, rather than the other way round.
I've just had to do a fresh install of Maverick, following a major problem, and I'm back to being unable to boot XP. The error is different from before and I don't want to start guessing at what to do about it and screwing things up still further.
The GRUB menu lists Ubuntu first, then Windows XP. If I choose XP, it takes me to my previous boot menu, with Windows as the first option. However, selecting this gives me
Code:
Windows could not start because the following file is missing or corrupt:
<Windows root>system32
toskml.exe
Please re-install a copy of the above file. Windows and Ubuntu are on separate hard drives. XP was fine until I re-installed Ubuntu.

telling me if this behavior of my openSuSE 11.2 installation is normal? I use a 64-Bit openSuSE 11.2 with kernel 2.6.31.x with root partition ext4. After adding and updating from repository kernel:/HEAD/etc to 2.6.34-rc4 I can not boot anymore due to a lack of module ext4. I thought today ext4 is stable and fix built-in in the actual kernel releases, isn't it? The error message at boot time: FATAL: Module ext4 not found. Which is right because in /lib/modules/<kernelversion>/kernel/ there is NO 'fs' subfolder. Isn't the kernel:/HEAD/ repository the official update path to get a newer major kernel? (besides openSuSE's Updates for security reasons) Do you know how I can fix it without self-compiling?

I'm running a dual-boot; Lucid and Win XP on a HP Pavillion.My time settings are about 8 hrs off between the two operating systems. If I correct the time in Linux, it will be wrong when I boot in Windows. If I correct it in Windows, it will be wrong again next time I boot into Linux.Besides the obvious solution of removing Windows from my machine (which I'm not ready for), what should I do to fix this?

I'm trying to install Fedora onto a computer that has Windows XP on the first of two SATA drives. Windows 7 is on the second drive.
I installed Fedora no problems on a 14 gig free space I created on the first drive and told it where and what my other OS's were. Fine so far. I didn't tell it to overwrite the MBR on the XP (first) drive. I took the second option which I "think" put the boot loader on the fedora partition.
All good - till I rebooted and I just saw my Windows 7 loader with my options for XP and Windows 7 but no Fedora.
So, if I overwrite the MBR on the first drive, will that mean I can't access my Windows 7 installation?
How SHOULD I set up the boot loader?

It seems that i am stuck using the 2.6.38-9 kernel, since no matter what i try, i can't update. I have had this problem since 2.6.38-10, but figured that the problem probably would solve itself after the next kernel update, sadly that was not the case.
I have had some worrying error-massages from dpkg about broken packages, which i believe might be the source of this problem, as it reported that the package "linux-image-generic" was broken. I removed the postinstall script from /var/lib/dpkg/info and updated both dpkg and aptitude.
I am not getting any more error messages, and if i look in the synaptic package manager, i can see that kernel 2.6.38-11 is indeed installed, yet i can't select it at bootup, even though i have tried to manually update grub.

why, after booting to windows for any length of time that upon rebooting to Fedora the system time is 3 or 4 or 6 hours off? Sure, it is easily fixed with ntpdate but is there a more permanent fix?

For some reason, every time I shut down and reboot my machine, the system time advances four hours. The local time here is EDT (-4hrs UTC). I have it set correctly in Yast and have the 'hardware clock is set to UTC' checked. However, for some reason, the next time I boot, the system time will be ahead four hours.

My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.
Code:
# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)
[Code]...
My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.

when I installed Ubuntu 9.10 I put in one time setting but it was wrong, and now I don't know where to change it. I tried to change the time preferences, but on reboot I am back to the wrong time.
I know the data is in there somewhere and I can change if I knew where it was.

How to make the system boot faster by removing the idle time between 5s to 10s? bootchart attached. It is Ubuntu10.04LTS by the way. One more hint, the screen black out for ~4s after "Begin: Running /scripts/init-bottom... Done." I don't know what is going on during that 4s, but my best guess is there is a way we can get rid of it.
Bootchart can be found here:

Ive poked around the forums a bit and cant see anything that addresses this. I have a new install of Ubuntu 10.04 LTS Netbook remix on an Acer Aspire one. (From a couple of hours ago.) It was able to boot all the way up once. Now after a restart it hangs after selecting Ubuntu from the GRUB menu. If I launch using Recovery mode it gets to a line 2.302026 ata4: Dummy and then hangs. I can boot with the live CD and access the partition that ubuntu is on. I can also boot into windows 7 starter (Blech) from the grub menu. (It is a relatives netbookThey want to try Ubuntu but keep W7 intact.)
I am at a loss of what to do, I would like to simply re-install it again to replace whatever did not get setup right, but I think it will just make a new partition and get really messy.
