Ubuntu :: Complete System Failure When CPU Is Stressed
Jul 24, 2010
I get a complete system failure when my CPU is stressed. It's not the temperature because when it crashes the CPU temp is only ~55 C. When it crashes the video freezes but the sound repeats itself. Example. I start handbraking a movie, then open a tv show in VLC. This is what I hear.
Did you get that tire - then it freezes
get that tire
get that tire
get that tire
get that tire
... etc
That continues until I reboot my computer. This crash is pretty reliable, as every time I load my CPU that happens. If I don't do anything CPU intensive, I don't get the crash. Also, if I only load up one core of my CPU, then everything is fine. However if I run something such as prime95 or handbrake (which both utilize all 4 of my cores) the computer will crash within 30 seconds.

I have been researching the web for a program which will allow me to backup my entire hard drive so that I can restore my system if need be. I am however unsure which is the best one to use if I want to achieve this:Somehow I want to back up my hard drive containing my ubuntu system byte for byte so that if the hard drive were to fail I could simply go to the store, get a new hard drive, restore my backup and be up and running again without having to do any re installments of ubuntu or any other programs for that matter.
What is the easiest program that does this? I would like it to support incremental backup.rsync with the "Back in Time interface"?bacula?
I've tried about a billion times to get this to install correctly to no avail. This is the amd64 desktop edition, but I've tried with the 32 bit as well. I have a lenovo W500. The system never boots off the USB. It gets through a bit, with text output, and then stops. Sometimes it doesn't even give an error message, and other times I get something like udev failed while loading some pci device. I've tried re-downloading the iso several times, different USB keys, different USB key creators, CDs, to no avail.
I then thought, well, heck with it, I'll just install 10.10 and upgrade. Nope, there's a GPG key error for some bizarre reason, which is tripping up apt, but it's not going to tell me what key that is so I can go and get it (and apt-key update does nothing). Command line upgrades fail similarly. So finally, I go for broke and try to just install the thing with Wubi. Of course, that eventually crashes too.
.After trying to instal 10.40 as a "guest" of Windows7 in its own partition on drive D I got all the way thru then re-booted to finish the install as requested. At that point after reboot I selected Ubuntu from the boot menu then it hung up after quickly displaying and overwriting some option numbers - probably for GRUB
I uninstalled 10.40 then tried Ubuntu 9.4. It worked better and gave me an option menu after the install reboot. If I chose "normal" it also hung up.I was succesful by chosing one of the other GRUB choices that it gave me.Now everything works but with an older version.
I have installed ubuntu 9.10 with karmic kernel and GNOME, on toshiba 512 MB RAm laptop. it worked fine but some times after complete shut down or sleep, it wont boot again. Laptop is completely dead and silent. I had to power it off, battery taken out and inserted again to get it started again. Then it worked all normal and fine. Why it happens and what i shud do next?
I've spent some time searching for answers to this and I haven't found much at all.Please feel free to post pointers to other threads that discuss this particular problem, if you find any.The problem is that in bash I want to mount an iso file to inspect the contents with the command:Code:sudo mount myCD.iso CDMount -o loopThe command works fine, but pressing tab to complete either the iso filename or the CDMount directory does not work. The completion suggestions I get are existing mountpoints which The completion suggestions should include the files and directories in the current directory. This worked with Ubuntu 10.04 and not with 11.04.
latest update to 11.3 a complete failure afterwards on reboot I'm instructed that I must first install kernel and to strike any key to exit which return me to grub menu. thats it for me and Osuse. 11.3 has been one bug after another and to much for me overcome. I will return once a day to see if anyone can fix this/
No wonder my network-career is not getting in the mood... always other trouble.
Thing is: reboot and ended with a black screen: "no video available". i hit the reboot button. same result. I just, today, added a new DVD/Read-Write, so i have assumed thats the problem. Unplugged it: same problem. Nothing, not even the BIOS-display.
As i once started a PC without keyboard connected i did remember that that doesn't work (if i recall correct it gave me some beeps, today nothing like a beep). I replaced the keyboard and could boot.
But i don't trust this result. If someone might give an experienced opinion i would be very glad (i got several pc's, but this one is the only one which is really usuable, though its still a 200€ one, but it does all i need).
I removed windows completely from my Dell Inspiron N5010 and installed Ubuntu 10.04.1 64bit. In windows I have the option to create the system image of system's current state so that if something goes wrong I could easily restore my system using that image( I am not talking about windows Restore facility). I wanted to know that if there is something available in Ubuntu also. I cant use Dell recovery media creator as I have deleted recovery partition. I have already used Remastersys and it also did its job well but after restoring my Graphics card driver did not work well.
I'm on ubuntu 10.04, and pretty new to it - over the last 2 weeks I've done probably 10+ fresh installs due to me not knowing the system, trying things. I looked for a way to back it up and found this guide - [URL]. When I use the feature as listet, it doesn't exclude the folders, and the system is "almost" the same as pre-recovery - and I'm copy/pasting. Is there a way to make a COMPLETE replica of my system, that I can launch when failed, so that - it's back to when I was "ok".. like all programs install post-copy to be gone..
My laptop running Ubuntu 10.10 had suddenly go to a dark gray screen that will not take any kind of input other than holding to power button down for 5 seconds. I'm not running any new or odd programs just Firefox, Openofice writer, and Pidgin. When I turn the computer back on I do not see any kind of an error message. I'm looking for any advice that will help me find the cause of the problem.
Beginning on the release day for Firefox 4, my system has been encountering hard freezes (no responsiveness to any key entry and only way to restart is by hitting the reset button). I had installed firefox 4 with no issue, but once it was open, it kept freezing my system. Some addons weren't supported anyways, so I uninstalled it and got back my 3.6. At the time I was using rtorrent, but within minutes of using it since the firefox install, my entire system freezes up.
Naturally I suspect HDD or RAM, but both have been extensively tested. Next I began browsing forums and found some tricks like turning off IPv6 or changing settings via HDPARM, but none have made any difference. I have moved on to using Transmission, and the problem still exists, but it occurs much less frequently.
I have also since then noticed that transfers of files from my 500GB OS/Torrent drive to my RAID 5 array and vice versa moves at 2-4MBytes/s, much too slow. So next I set up my torrent client to download directly to my RAID array, and lo and behold no freezes! Also, while transfering data the system moves at an absolute CRAWL, as in browser windows turning gray, saying that they have stopped responding, etc. I ran a fsck on my 500GB drive, which instantly told me my file system was clean. I'm at my whit's end here! I hate re-posting on a topic, but I feel like I've tried everything!
I have (had) Debian Testing running on a 250GB IDE hard drive, partitioned normally.
I also have 4x 1TB drives in a raid 5 using mdadm, and 2x 500GB drives in a raid 1 also with mdadm.
I put the two arrays in lvm using:
I then used "lvcreate" to make storage/backup 300GB, and the rest went to storage/media (approx. 2TB usable). I put an xfs filesystem on both and mounted them.
All was working fine until the system drive shorted out and died on me this morning. As far as I can tell, all my other drives and everything else is fine. I do a daily rsnapshot of the filesystem, which of course is residing on storage/backup (stupid, I know). So I have full backups of everything, but I'll have to put a new hard drive in and reinstall Debian before I can restore everything.
I've reinstalled before and simply reassembled mdadm arrays and remounted them before with no problems, but this is the first time I've used lvm, so I'm not sure what I have to do to restore everything. Is it as simple as reinstalling the system then doing a:
Since having installed Lucid Lynx, I have several complete system crashes a day, no matter which applications I am using. Lucid crashes without any error message and the system reboots. I have had no problem whatsoever with Karmic Koala (also switched from ext2 to ext4 when installing Lucid Lynx). Is there any probable reason for that or a workaround? Can I paste any logs here for anybody to figure out what might be going on? When I try XP which is also install, the system won't crash (so far...), so I don't think it's a hardware problem.

I would like to find out how to back up a complete Ubuntu system, and then restore it on a clean harddisk.I have been running dual booting with Win XP until now. I am running Ubuntu 10.04, but have installed quite few add-on. I would like to make an Ubuntu-only machine now, with all the same apps still there, but dont want to go and download everything again. I am looking for a way I can back this entire Ubuntu installation up, and then restore it to a clean drive.
I have an Acer aspire notebook.graded from lucid and now I have a really big problem:every time i disconnect the ac-adapter from the pc, the system freeze completely, became unresponsive to commands and to sysrq. i need to phisically turn off the machine and then back on.
Just curious if it is possible to schedule a complete system shutdown and start up?
My box with ubuntu server on it is only used as an ssh/proxy server, so I would like save on energy costs and add a layer of security by completely shutting it down during the hours I do not use it.
My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.
Additional information:
1. LSPCI output:
Code:
00:00.0 Host bridge: ALi Corporation M1697 HTT Host Bridge 00:01.0 PCI bridge: ALi Corporation PCI Express Root Port 00:02.0 PCI bridge: ALi Corporation PCI Express Root Port
When I try to shut my PC down (press the shutdown button in KDE 4.3.4), the desktop quits, but the console screen does not appear (the CTRL+ALT+F1 screen). Well, technically speaking it appears but only a still (not blinking) cursor is shown, otherwise the whole screen is blank. This means that not only the X freezes but whole system, because the keyboard is unresponsive too. It happend multiple times now, and every time I reboot after such event, some kde rc files (amarokrc, kmailrc, etc...) get deleted due to the automated filesystem check (unclean umount), which means that I have to reconfigure these apps again.
My home partition is on a separate EXT2 partition (this way I have full r/w access from winxp) and every time this is the only one which gets corrupted. The system partition (which is EXT3) is always intact (no fsck starts on boot). I'm using Debian Squeeze by the way.
when my monitor turns off after 30 minutes, I cannot do anything after. We're talking complete lock down of Ubuntu 10.04 64-bit. Not even alt+printscreen+REISUB reboots the machine; I have to do a hard reboot (which sucks and is hard on hardware).
All of these freezes happen either while I'm in Nautilus or I'm opening Nautilus. The usual Ctrl+Alt+Fx (x being one to six) to get into the backstage does not work. If I have some music open then it would start looping the last couple of seconds.Now generally I would go check the logs, but I see no nautilus logs so what should I check?This is all pretty recent. I think that this started to happen when one day exim4 (and some packages all marked exim) got updated but I cannot be certain. Major playing-around after that would be some Wine issues but the system froze once before all that Wine fun.So step one, what should I check?
Image Hard drive Ubuntu Operating system 9.10 Complete back up and restore. Changing over Hard Drives need a complete back up not just save files. So the image can be restored on any hard drive that restores the computer to its original state before it was imaged.
I'm at a loss in trying to debug a problem I have with my media centre. Basically I'm getting random system hangs and when I say hang I mean proper hang - processor stops dead. No animation, not network connectivity, no keyboard/mouse response, nothing. As for it being random - it has happened during movie playback, during idle, after being up a short time, or a long time, it doesn't matter, so it can happen any time really. The logs show nothing suspect, except they just stop and there is nothing common between the logs of two failures. It happens on both my 'old' ubuntu 9.04 partition and on my new 10.04 partition.
I recently installed Lynx 10.04 amd64. Twice now, my entire file system has become unusable -- each time after a short power outage (2 seconds).
In the first setup, I had two primary partitions: 1) / that was ext4; 2) /home that was ext4.
In the second setup, I changed the /home to ext3.
Both times, after booting up following the power outage, I received a message saying that "serious errors" were found in /home. But, after several reboots, I was able to login and use the system. Then, some time later, I would started getting "Read Only" messages when trying to write to the file system.
fsck gave the following message: "/home terminated with status 4". I received numerous "I/O error" on sda messages.
My question: Is this vulnerability due to using ext4 or is it related more to something else in Lynx 10.04? Further, what can I do (other than buying a power backup device) to avoid my file system becoming unusable after a power outage?
I recently had to restore my system via clonezilla due to hdd failure. I frequently back up my /etc/apt folder as well as some other configuration files and settings that I use in my system to bring my restored image up to date with my ever changing preferences, etc.
I noticed the problem when I replaced the etc/apt folder with my backup version. After replacing the folder, I ran 'sudo apt-get update' and imported a list of all my previously installed software. Then I ran 'sudo apt-get upgrade'. I didn't get any errors at all during any part of the update and upgrade process.Then this popped up in my panel, and won't seem to go away.
I am running Fedora 8. Each time I run a YUM command, I get the message that there are unfinished transactions, and to run yum-complete-transaction. Upon running yum-complete-transaction, it fails with this error. How can I remove this uncompleted transaction so I can finish the last one?
I was just trying to get used to everything and I noticed something in the task bar that said you have updates that failed to install (or something along those lines). So I opted to install them manually with YAST2 and during the installation some of the files were failing to download, I was unsure what to do with these files (their was a ton of them, I had to actually sit at my pc for over an hour because I couldn't let it go through on it's own due to all the failing downloads and installs) and so I just decided to skip them, everything seemed to be going along normally. Then my computer froze, so I restarted and tried to boot into opensuse and it kept freezing, (I even went to my brothers house to play the xbox with him for a while) and no matter how long I waited for it wouldn't boot into opensuse. I tried the failsafe mode and it just kept coming up with an error (I probably should have written the error down, I wasn't really thinking about that at the time) and after about half a dozen tries, decided to reformat everything all over again.
So with these failing downloads in YAST2, what am I supposed to do with them? If I retry they just keep failing, so the only other options are abort and skip, am I supposed to skip them or is that what caused this to happen in the first place?
