Ubuntu Installation :: Mythbuntu System Hangs After Regular System Update: "out Of Memory" Errors
Aug 4, 2010
I have Mythbuntu 10.04 installed on an exclusive HTPC and working great... until tonight. After letting the system update some packages (161 packages if I remember right), I suddenly have an issue where the graphical system won't start. After researching I found three error messages that might be causing that.
1. At the start of splash screen I see "UUID=xxxxxxxCD7 not ready yet or not present" I checked in /etc/fstab and found that this is the swap partition. I don't remember seeing this before so this could be the culprit.
2. I'm not at the computer in question right now but I saw a Plymouth error about "mountall" and then the message "plymouth command failed". Not sure if this could be the main error.
3. after a while (usually ca. 1-2 min) I receive thousands of errors of the kind "out of memory"... "kill process XXXX" (process vary wildly e.g. dbus-daemon, mysql, etc)... "process killed"..."respawning"
After error 3, I'm not able to switch to graphical console (ctrl-alt-F7). If I was in the graphical console at this moment, I simply can't switch to the CLI console. I'm always afraid of updating my system since I've seen lots of things breaking afterwards (usually the proprietary graphic drivers) but this is really strange.
I did a fresh install of Ubuntu 10.04 on a desktop. I then did the system updates and on the reboot the system now hangs at the splash screen before the login screen. I only get a blinking cursor on the text-based terminals. I don't see the grub menu, I assume because Ubuntu is the only OS on this machine. So I can't boot to single user or text-only mode.
I have a problem with the kernel update to 18.104.22.168. 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?
Is there a system admin tool for RHEL on montioring and logging system memory used and released that can dump to a log file?I'm having an issue with memory not being released when an application is closed. I need to have a tool monitor and log so I can troubleshoot to verify that it's an application not the OS.
Just upgraded to 10.04 from 9.10. upgraded from update manager. System would not boot. Booted live cd and used the 9.10 menu.lst. Now boots but takes a long time. I don't know much about the kernel. I assume they are listed in the /boot directory and are called by menu.lst (dual boot w/ XP) (btw: I am ready to get rid of XP once I get this fixed). 9.10 appears to use 2.6.31-20-generic, therefore, I assume 10.04 uses 2.6.32-25-generic.
Could not download all repository indexes. The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.
I upgraded F14 to F15 using installation DVD. I have been upgrading since F11 with no problems. Upgrade went well, no issue. After the reboot, the system hangs after the last line systemd.
These are last lines from boot.log: Starting LSB: start and stop xinetd... Started LSB: Mount and unmount network filesystems.. Starting Permit User Sessions... Starting xinetd: Started Permit User Sessions. Starting Display Manager... Started Display Manager. [OK] Started LSB: start and stop xinetd.
Right now I am on system rescue CD, can mount partitions and read logs. I would like to avoid fresh installation if possible.
I had to resize the win partition, making a new partition for Ubuntu of about 15GB. I then installed the system. Everything went without problems. I was able to boot once, and verified that everything worked as intented.
However, after that, 90% of the times I reboot the bootup process hangs at a blank screen (with a blinking underscore), immediately after grub selection. If I select "recovery mode" in grub I can see the bootup messages, but the process hangs, all except one time, right after:
Code: [2.304418] ata2: DUMMY [2.304487] ata3: SATA max UDMA/133 abar m1024@0x58344000 port 0x58344200 irq28 [2.304584] ata4: DUMMY
and does nothing more. There are no error messages or hints to the source of the problem, to my eyes.I've noticed that sometimes even the loading screen of the live cd will hang indefinitely, leaving me no choice other than a hard-reboot.
The rare times that the system does boot normally, everything works normally. I've tried installing using both the ext4 and ext3 filesystems. I couldn't find anything like this on the forums. Am I doing something wrong? Do you need more details?
In the last few weeks I upgraded my Ubuntu from 8.04 to 8.10 to 9.04. No problems, everything went well. But yesterday I tried to upgrade from 9.04 to 9.10. Everything seemed to go OK until the upgrade was finished and I had to reboot. After the reboot, no Ubuntu anymore... I get GRUB, but when I continue to boot the latest kernel, I don't see any harddisk activity anymore after about 2 seconds.
Here on the forums I read that one should run the boot_info_script when having boot problems, so I already did. I booted the system with a 8.04 live USB stick. And here is the result of the boot_info_script:
I had Fedora 13 64 bit before which was correctly reporting memory as 4GB. After I wiped off Fedora 13 and did a fresh install of Fedora 15 32 bit, the memory is reported as 3.2 GB in the system Info and also in free -mt command code...
Where is 600MB memory gone missing? I checked the BIOS setting and it correctly says total memory is 4GB.
The hardware is exactly same and I did not change anything.
I got an Asus M3A78-T motherboard last year, along with a Phenom 9650 CPU and 2GB of RAM. I originally tried to install Sabayon, but it would occasionally hang while running. I decided to give Fedora another try (wasn't happy with FC4 a few years back) at the constant chiding of my friend.
My first try was with the x86_64 Fedora 10 ISO, using an IDE hard drive and CDROM. It would hang a little bit into something like 'copying system files, at the same place every time. Thinking it was a bad burn, bad iso, or something (checksum and image verification passed) I went ahead and got the DVD ISO. The DVD would always hang a little bit into "Formatting file system." At this point, I have tried EVERY other combination of hardware - swapped out ram, CPU, PS, bought SATA hard drive and DVDROm drive, unplugged the mouse, and even the case pigtails for USB and Firewire. It always hangs in the same place. Somewhere along the process, I took the motherboard back and exchanged it for a new one. Still fails, and in exactly the same place.
The system hang is a hard lockup. Mouse freezes, no keyboard activity (even LED status changes.) The drive activity LED will go out and the progress bar stops advancing.
I'm surprised I'm not seeing anyone else with this problem - I thought this board was a bit more prevalent, but I'm guessing not! What's my next step? I would create a bug report, but I don't know what subsystem is causing the hang. I suspect SATA drivers, but I'm not sure how to test that.
And one other clue - I get a scrambled video screen before it comes up to the first X install screen:
It only lasts for 5 seconds or so, then comes up okay.
i get file system errors on boot up. found logs in /var/logs but cant access them. second best thing i can do is to re-install debian but no one seems to want to say how thats done. my disk wont run in wine (some error i dont remember) so i cant use my CD /flashdrive to re-install.
1) i need to read the log files and try to fix the install 2) if i cant fix i need to know how to wipe the OS and do a fresh install
I've just upgraded to Natty. During the upgrade no errors showed. However, when I now boot ubuntu (either recovery mode or normal), the boot process hangs at:
'checking battery state'
I searched for similair problems in this forum, but the solutions in other posts(sudo apt-get update & upgrade etc.) did not help. I'm not sure if it is related or important, but when it hangs, it also shows something like:
I installing Fedora 12. I did ALL the same as in the installation guide, GRUB installed into MBR. And after installation and rebooting - nothing happens, after BIOS messages there is nothing - computer hangs. GRUB seems to be not installedI have 2 hard disks. At first I tried to install on the 2-nd drive(it is slave). Afterward I detach one disk and try with only one hard disk(it is master). Nothing changes - computer hangs.
I upgraded from FC10 to FC11 yesterday.I had no problems using FC11 after I looked into the bootloader (not intuitive - Ha!).Tried to boot up this morning; and things seemed to work well until I tried to call up Firefox (added a few themes yesterday).The window pops open; but the computer freezes on the spot with an alarm (generic "beep", w/o the finishing "p").Tried it with Epiphany; and I get the same results with the exception of actually getting to the Home Page.Yum works for the most part - I reinstalled Firefox (no effect); but couldn't reinstall epiphany (keeps saying "there is no such package - did you mean 'epiphany'". No typos on my part - go figure). Doing Software/Package Updates (via System Menu) freezes the box as well.Did it with the system monitor on. It doesn't appear to be related to CPU Usage.
Had a FC10 liveUSB and used it for awhile (e.g. to check out the forums). After giving my ISP some grief about downloading speed, immediately received a note from their Abuse Department, saying that my machine had been infected with a virus and had been sending spam emails (post upgrade to FC11).
who is having issues with lockups check their /var/log/messages for this

It is not difficult to set up a regular local repository (rpms) and manage a fedora system with it using yum. I wonder if the process is same for deltaRPMS. Has anyone successfully set up a local deltaRPM repo or is this something reserved for online repos? How does one achieve this?
I just allowed Update Manager to install the latest security updates to the Linux kernel, header and xorg and clicked on restart system. After selecting Ubuntu from the system's boot manager I'm dropped into a Grub command line and don't have any idea what to do next. I'm running Ubuntu 9.10 inside Windows 7 on a Toshiba L500 laptop using the Wubi setup.
After Ubuntu update, the system won't restart. Now, after BIOS start, I get the following message:" udevadm trigger is not permitted while udev is unconfigured."Then, after several seconds appear the following message:"Gave up waiting for root device.
I was updating my netbook to the 11.04 when it crashed (I thought is was on the grid, what do you think? it wasn't!) Now if I try to do it again I get a notification and then it stops. These are the last few lines of/var/log/dist-upgrade/main.log:

I updated my Ubuntu 10.04 on Dell 1330 and on the next boot it failed. I get a series of messages, the main point seems to be that it can't find the files it needs to mount.I tried booting from the live cd I used to install 10.04, but it can't boot either due to wrong user id error and maybe trying to boot from wrong kernel?At this point I am willing to just wipe the hard drive and do a fresh install but how to do that if I can't run the install cd?Or is there a way from initramfs to solve this?I tried mount /dev/sda1/mnt but it says cannot read /etc/fstab no such file.libdevmapper
I'm running Ubuntu 9.10 in a dual boot alongside Windows vista on an HP DV6000 laptop.It's been running smoothly for months. No problems.Today, I was in Ubuntu, and the Update Manager asked me to update (ok) and then said it needed to restart. I hit the restart now button and the system started to shut down, but never fully shut down. It's in a kind of loop, trying to start up, but not going all the way, and then shuts down again.I did a hard reboot but still nothing - the same loop. I don't even see my HP startup screen, nor can I access the BIOS, much less Grub.I put in the Ubuntu startup CD and it tries to read from that at startup, but then fails and returns to the same loop.
I installed Lucid Beta a few days ago and was happy with the way everything worked. The system wanted an update on Thursday night, I installed it and then carried on using it for about an hour, it was then shutdown normally with no errors. On Friday morning it would not boot. I pressed the "on" button it came on, all the other lamps lit ie Caps and Num Lock, the battery light is on anyway, but the hard drive light is not flashing, it's as though it isn't being accessed, but I can hear it? There is no display on the screen. I'm running an Acer Aspire One. My initial thoughts are bios related, but I can't see how that would have changed, then I think maybe the Harddrive is knackered.
I have a server that was running 10.04 and I decided to upgrade it to 10.10 as I had already done this successfully to a different server.The upgrade was about 3/4 way through when I can't exactly remember why but it had to shut down I think it may have got stuck on a simple package update anyhow when I next turn on the server the login screen if different with a purple background and a popup about a gnome power installation error comes up after I enter my user name and password the login box freezes up and a box comes up saying that a unknown process has stop working and gives me the options to 'lock screen', 'cancel' or 'log out anyway' if I press 'cancel' the box disappears and nothing happens if I press 'log out anyway' the login box the bottom bar and the pop-up disappear if I wait a little 'update manager' comes up saying I can partly update some packages after I enter my password to do this though it all closes and does not reappear all you can do is move the mouse.
I'm running Kubuntu natty on grub-efi-amd64. I've just received notification of a bunch of new packages to install, I believe part of it is a kernel update. When I click on "apply" a window comes up which says "Additional changes are required to complete the task". "2 packages to remove" lists "grub-efi" and "grub-efi-amd64". It lists 5 packages to install 3 of which are linux kernel and 2 of which are the bios version of grub.
How can I update my system without having efi-grub removed?
