Ubuntu :: Soft Lockup - Cannot Boot At All
Jul 30, 2011
I cannot boot into Ubuntu at all. I have two kernels installed, 2.6.35-28 and 2.6.35-30. The first thing that happened today was that I wasn't able to boot into the latter. I was shown the (in)famous "BUG: soft lockup - CPU#0 stuck for 61s". At this point I could still boot into the 2.6.35-28 kernel. But after shutting down and starting again an hour later, I got the same message when trying to boot into 2.6.35-28. I have tried leaving out the boot options "splash" and "quiet" on both kernels and also adding in "noapic". No combination helps. Needless to say, booting into recovery mode doesn't work either. Up until today, I have been able to boot into both kernels with no problems.

I recently installed 10.4 on my laptop and I love it, so I wanted to install it on my desktop. It's a somewhat older computer, AMD3000+ nForce 2, 1.5 gigs of Ram and a Radeon x1650. Whenever I try to start the Live CD I get the error soft lockup - CPU#0 stuck for 61s and it doesn't continue.

i'm trying to Debian 8.1.0 on my notebook Acer Travelmate 2200. Currently i have very outdated version of Linux Mint. It works fine but I prefer keeping system updated. Only way to get updated system now is install new one, and here i have a problem. After CD/ISO booting, installation looking for a mountd devices, etc. then i got statement that CPU stuck for x sec. The same statement appears every 20sec. I was trying it on other linux distr's they give the same error. I didn't overclocked my notebook, his temp is ok. I'm working on it few hours each day, it didn't overheat. Someone told me thats bug of 2.6.x kernel but I'm trying install new system with 3.16.x.

11.4 Boot Freeze That is there is a BUG: soft lockup - CPU#0 stuck message and the boot hangs.The modprobe/migration codes are not identical with the linked thread. I'm stuck with CPU#0 at [modprobe:138] and #1 stuck at [migration1:8]. Generally after 61 or 63s.
This is a zypper dup from latest 11.3.The machine boots with acpi=off, luckily. But I'd like to have it all working.The forum says I can't post attachments; hwinfo output seems a bit copious to quote inline. But I'd be happy to provide any additional info obviously.

I have a system running CentOS 5.5 (194.32 Kernel) that has been working fine for about 8 months. I found it stuck one morning dumping a Soft Lockup Kernel message every 10 seconds and have been trying to find out what is going on - here is what I've done and found.
System is a Core i3 with 4Gb DDR3 ram and 2 1.5Tb SATA drives - everything is less then 1 year old with not too much load (this is a backup system for my server - a twin and the other works fine)
Intel Mobo: DM55HC
Rebooting the system (after doing a fsck on the drives with lots of errors) it runs for about 20 hours or so and then drops back into this problem.
Prior to going into the soft lockup it reports that the Journal has aborted on one drive or the other and drops into a Read Only FS.
There is nothing in the logs apart from the aborting journal message and the soft-lockup)
Tried fsck with badblocks check on the 2 mountpoints for both drives (dunno how to check the swap partition) - nothing I could see there.
I have tried memtest for about 36hours. No errors
I ran smartctl long tests on both drives. No Errors

It seems I've run into a bit of a problem. I recently upgraded to the latest kernel 2.6.32-24-generic (x86) but when I reboot into the new kernel and type in my password the system hangs, same when using a keyfile on the root file system.to give an outline of how the disks are setup.3 hard drives
sda1 / = unencrypted
sdb1 /home = encrypted w/ luks
sdc1 /backup = encrypted w/ luks
When i boot to the original kernel 2.6.32-21 I'm able to successfully get into the system.

I've installed Ubuntu 11.04 on a Fujitsu Esprimo E900. During installation, I've used the guided encryption setting because neither GRUB nor LILO would ever install on the LVM configurations I created myself. So after installing Ubuntu 11.04, when I boot regularly, the computer freezes completely. When I try to launch the recovery mode kernel, I get this far and then the computer locks up, too. Ubuntu lockup during boot by germanium, on Flickr
You can see the label is sdb5_crypt which is a bit odd since the partition is on /dev/sda. However, I already tried changing grub.cfg to /dev/sda instead of /dev/sdb but that didn't do anything. This is all a bit odd to be. The funny thing is I've been trying to set this computer up for a month and I'm a professional programmer (Java, JavaScript, Groovy) with 20 years of programming experience and I never thought Ubuntu would be this hard to install on a more-or-less stock Intel box.

I have a new Fedora 11 install with all updates working on my: Dell XPS M1330 laptop with nVidia GeForce 8400M GS
I wanted to install compiz fusion on Gnome so I followed these step by step instructions from:
Fedora refused to boot, locking up during the process.
Here is what happens...
After updates I had 3 options at boot up:
A) If I choose the TOP one (newest) it will boot up to a black screen and nothing else, I get a white block which moves with mouse. I cant get a shell and any key I hit just echoes back...ctr-alt-del will result in normal shutdown process displaying.
If I watch the services start (F1) I see all -OK- except: nvidia.ko: Driver already enabled
The boot continues with all OK until it gets to:
STARTING atd:
at which time the screen flashes for about 7 seconds and locks up.
B) If I choose MIDDLE boot option and watch the boot process I see most services start OK except:
-[OK]
Checking for module nvidia.ko [FAILED]
nvidia.ko for kernel 2.6.30.8-64.fc11.i686.PAE was not found [WARNING]
The nvidia driver will not be enabled until found [WARNING]
Driver already disabled
-[OK]
Then the services continue on with [OK] until a few seconds later the screen halts with a mess of colors and symbols on screen and system stops booting. Any key pressed simply echoes back with no other result. Again ctrl-alt-del refreshes screen and shutdown of services proceeds normally.

There is a bad bug in OpenOffice that keeps giving me a hard lock. I can not even shut down the program, I need to force a reboot. I can make it happen repetitively. Anytime I am working on a presentation in OpenOffice Impress an am working with sound files this happens. If I am moving the sound file icon around on the slide it randomly locks up the file I have open. Another way is resizing the icon and it will also lock it up.

After updating to 10.10, I started getting hard freezes on a regular (read: every 10 min.during use) basis. A bit of diagnosis showed me that it was only a problem during periods of intensive I/O activity (moving files, downloading, etc.).A bug report started with:BUG: soft lockup - CUP#0 stuck for 61s! [kswapd0:26]I reinstalled 9.04, and was able to successfully copy 15gb from one drive to another. I upgraded to 9.10, and copied it back.Upgraded to 10.04 and copied it again. 10.10, it copied a few mb and froze.

I'm putty'd into an Ubuntu server box and have EDITOR=emacs set. However whenever I run crontab -e my shell locks up.
I can use emacs normally by typing emacs from the command line, so I'm not sure what problem is. If I set EDITOR=vi I can run crontab -e and it opens in vi

Nearly every time that automatic updates finishes installing the software and requires a restart of the OS, the PC locks up at the 'Ubuntu' screen with some dots beneath it.
I have been just been forcing it down by powering off/on the PC - which I figure is probably not a safe thing to do but don't know what else to do or how to troubleshoot this problem.
I've looked at some of the log files but can't make any sense of most of them nor do I know which log file might show the problem.

Running updated 11.04 on a older Dell Precision 360n. Been having random system freezes for the past month that requires a hard restart (REISUB doesn't work) each time. Sometimes the caps lock and scroll lock LEDs blink, other times not. sometimes it happens during boot, other times during normal usage. There hasn't been anything in any of the logs (except once, which I'll post below). This happened running 10.04 and 10.10 as well. I've run PC-check a few times and all hardware diagnostics have passed. Until today, i've been able to boot and run Trinity Rescue Kit 3.4 to mount the disk and examine the logs (and do backups), but now TRK won't boot and spews kernel panics when loading.

I just upgraded from F11 to F12 and get this error:
[drm] nouveau 0000:01:00.0 GPU lockup - switching to software fbcon
With Ctl-F2 I can switch to console and login, so the system is running.
"ps -ef | grep Xsession" shows constant changing pid for Xsession, so I guess Xsession is continuously being restarted for some reason.

I'm not sure if this helps and I'm not sure how to tell anyone what I found, but was a problem in Fedora 10 and 11 were VM's running in KVM would lockup due to (disk or network) IO activity. The problem silently vanished as soon as I installed Fedora 12 as my VM. I upgraded my VM to Fedora 13 and the problem re-surfaced. Oddly, no other distributions seem to have this problem any more judging from Google. My configuration:Host = x86_64, 4 cores, Fedora 11VM = i686, 2 virtual cores, Fedora 10, 11, or 13 (Fedora 12 works)What worked for me was using only one core in my VM. Things have been stable for a few days now

I've been running a Dell Latitude D600 laptop on -current for a couple of months. After the last kernel update, I needed to switch to the non-SMP huge kernel due to lack of pae instructions.Since then, I've seen 2 complete lockups. They've both happened when it was sitting idle, and in both cases, Xfce is gone, and the console is spewing kernel messages faster than I can possibly read.

I am running Centos 5.5 on a IBM Think Centre. I am using it for File sharing Samba and one moment it would be working find then the external 1TB HDD would lockup and I would have to reformat it in order for it to work. I don't really have and other information but that is basicallly what happen even if i manually go to the Centos server it would not allow and thing to be created.

Running 5.5 64bit. Same machine has been running since release of 5.0. Normally the machine runs the nvidia driver from elrepo but I switched back to vesa (thinking the Nvidia driver was the problem, no go). Machine starts up normally and everything is fine until when the login screen should appear. Instead of the normal login screen I have a black screen with the mouse swirly going round and round(which normally occurs for a second or so). This all started when I went out for dinner. When I came back and wiggled the mouse all I got was the swirly. Rebooted, same thing. I can switch to a tty and log in normally. xorg log looks clean. Both drives are accessible via cli (/home is on a separate drive).

I am trying to make a NAS solution for our club, which should contain different data for download. I have been looking at freeNAS, openfiler and other solutions but they don't offer quite what i want.I want data security, but trying to avoid software and hardware raid.Windows Home Server has a function, where it copies the data from the 'main' storage disk and over to the 'backup' data storage drive automatically.

I just installed 10.10 on my dell e1505 laptop. it has an ati radeon x1400 video card. this is my first time using linux on this pc. anyways my problem is that the laptop screen looks a little soft or slightly out of focus. its also very slightly stretched...but just barely. almost to the point you dont notice unless you are looking for it. now i also have an external monitor and it looks perfect. ive tried changing the monitor resolution but it doesnt help and sometimes it makes both screens flicker like its having a seizure! i forgot to mention that sometimes when opening an app or installing an app. the external monitor goes black for a few seconds. the laptop monitor doesnt though.

I've just installed OpenSuse 11.3 on my two Sony Vaio VPCF11Z1E machines (which have a Geforce GT 330M graphics card).Both machines appear to setup correctly and behave normally, but at seemingly random intervals (of the order of magnitude of 15-30 minutes) the whole system locks up for no readily apparent reason. I can still move the mouse pointer around the screen, but I cannot click on anything, and the whole keyboard is unresponsive (including any reasonable ctrl-alt-xxx which might normally help). The only way to get out of this seems to be to press and hold the power button to shut the whole machine off (which is not ideal!)

I am not sure of which LibreOffice version I am using because I can't open the ****ed program. So here's what's happening: I start LibreOffice, my screen looks unusual (it tiles a section of the screen that is the same size as the LibreOffice window (I think) across both of my monitors) and my system locks up. I am unable to use Ctrl+Alt+Backspace, Ctrl+Alt+Delete, Ctrl+Alt+F1-F8, or any other keyboard combination. No mouse click registers and the cursor acts as if the mouse is in one location (if the system locked up with my cursor over a link, the cursor stays like that) BUT the mouse still moves. Also, if I am playing music when it locks up, I can continue to hear the music and the music continues to shuffle through my playlist.
I am able to access my machine normally through ssh and the only way I've been able to fix this is to hold down the power button or pull the power. I have not identified what action causes the system to lock up, the only thing I've noticed is that LibreOffice is open every time this happens (It's happened no matter if Writer or Calc is open). The system almost always locks up upon startup of LibreOffice if the recovery window pops up, otherwise it locks up at some point during my LibreOffice session no matter what. I have not touched LibreOffice on my other machine's openSUSE installation, so I don't know how reproducible the problem is. Let me know if you need any extra information or if there are any diagnostic commands I could run.

I've just installed Scientific Linux 6 (equivalent to RHEL 6) with OpenOffice.org 3.2.1
If I click on a file to open it with Writer, the program locks up. If I run Writer first and load the file, all seems to be well. But if I launch Writer from the command line, I'm left with the error
The ? are my insertions, replacing invalid codes.
This happens with all text files, new or old. Has anyone else seen this, and is there any solution other than re-installing OpenOffice?
