Ubuntu :: Random Reboot Shutdown In Karmic 9.10?
Jan 19, 2010
I recently migrated from Hardy 8.04 LTS (32) to Karmic 9.10 (32) so that the restricted ATI drivers and CCC would work correctly - that part is basically fine.
The problem for the past couple of weeks has been Karmic randomly shutting down, and rebooting the system after 1 or 2 hours up-time.
Why would this be happening, it was fine for the first few weeks after installing Karmic.
My system currently consists of the following;
Gigabyte MA790FX-DS5 mainboard - Jan '08
AMD 3.0Ghz Phenom II X4 945 CPU - Oct '09
4GB DDR2 Kingston HyperX RAM (1066 MHz) - Jul '09
Sapphire ATI HD5770 1GB GDDR5 video - Dec '09
Cooler Master Extreme Power Plus 640 watt power supply - Nov '09
Cooler Master Centurion 5 CAC-T05 case - Jan '08
1 pata 500 GB, 3 sata 500 GB & 1 sata 640 GB drives
2 DVD burners (Pioneer and LG)
2 x 19" (4:3) Samsung SyncMaster 943N LCD monitors
I used to have lmsensors working with the Athlon 2.8GHz dual core in Hardy, but they wouldn't work with the new Phenom 3.0 GHz 945 CPU in Hardy (and they still won't work in Karmic).
Th upshot is that I don't have cpu, system, or graphics temps; nor do I have any fan speeds, so I don't know what temps or fan speeds my system is running without rebooting into BIOS (which isn't much good as I really need to know what's happening when I'm using the OS itself).
Does anyone know what could be causing this random shut-down/reboot problem?

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

I've been using Ubuntu on and off since 8.04, but only last week decided to make a real switch across to it.After installing 9.10 64bit though, my laptop while running Ubuntu just turns itself off at completely random times - it doesn't seem to go through any shut down procedure or anything, it's more like the power's just suddenly cut. It sometimes happens 5 minutes after being turned on, or sometimes 4 or 5 hours, it really is random.I really have no idea where to even begin trying to stop this. I think it must be a software thing because this has never happened with windows or earlier versions of Ubuntu, but other than that I don't know what to do to stop this.I'm dual booting Windows 7 32bit and Ubuntu 9.10 64bit, and this is on a Toshiba L350-D 11-D laptop, which has a 64bit AMD processor.

System: T400 notebook, intel and ATI graphics, only intel graphics enabled. 9.10 64-bit, whole disc encryption. New install. My system recently started crashing periodically. At first there was no problem. There is no particular program that causes a crash. I havent edited any configurations. The most recent packages I installed were some data recovery packages and Gkrellm. Is there any way to find the time of installation for each package?
I upgraded to kernel 2.6.32 Ive been looking at the syslogs and before every crash there are several lines of:
Jan 9 20:46:24 username wpa_supplicant[1677]: CTRL-EVENT-SCAN-RESULTS
Jan 9 20:48:24 username wpa_supplicant[1677]: CTRL-EVENT-SCAN-RESULTS
Jan 9 20:50:25 username wpa_supplicant[1677]: CTRL-EVENT-SCAN-RESULTS
I did a google search on this error but the only real suggestion I found was the kernel upgrade.

1st post @ LQ. Ubuntu user since 2007ish. Lots of PC experience... now vexed by upgrade from 9.10 Karmic to 10.04LTS Lucid.
The problem: random freezes whenever I boot into Lucid as user through usual Grub menu. The freeze sequence is: 1- screen stops, 2- mouse pointer freeze w/ no effect on click but moves freely and keyboard is useless, 3- screen blacks out for about 30 seconds and then returns but is unusable and 4- constant HDD activity for about 5-10 seconds. I have waited several minutes for a recovery of some sort but no dice. I reboot via on/off or reset button. Ubu deletes 2 inodes and then I'm off and running again.
If I boot through the recovery console there are no problems at all. The recovery console sequence: 1- select recovery from Grub menu, 2- at recovery menu select drop to root command prompt, 3- give root password, 4- enter 'gdm' at console prompt, finish boot up in my only user desktop (not root.)
I have not been able to find any log files that show an error message, but I'm not so tech oriented that I would necessarily know one if I saw one. Through many hours of browsing posts describing Lucid problems @ UbuntuForums (one of which has over 1,000 responses) I have found my '.xsession-errors' file (attached) is full of data.code...

Is there anything in Karmic that would get something to run at shutdown?I have a US Robotics 56K message modem ( USR5668 ) which receives faxes during the day, and has to switch to answer machine / fax at night. It has a memory when the computer is switched off - which is handy, and all the phones switch over to the message modem extension automatically.All I want is to do is send the command AT+MCA=1 to the serial port ttyS0 at shutdown.
Any sportster owners might say that this goes to answer machine only, so if they want to tell me the correct string for answer/fax please feel free.I do have vm installed (or whatever vgetty calls it),

I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."

Now, this is the case:
Yesterday, i tried to boot up my laptop but the battery was uncharged and it was unable to boot ubuntu karmic 64 bit. so i tried to plug the charger as soon as possible but when i looked at the screen, there was a huge black blank screen. so i had to restart it manually by pressing the power button. Now, i can see the grub screen, i can choose one of three kernels and the Windows. But only Windows can boot but the others doesn't. And also, grub timer does not work not. It does not count down to zero and autoboot the default os. I tried to reinstall grub but everytime , i got problems. Here is what i tried to do. In another try here, i failed again. In chroot, i could not "apt-get install" as it said i wasn't connected to internet (but i was), and in another try, it could not find p/rmonct /mnt/etc/resolv.conf.

I've been using a LiveUSB I created using unetbootin from Windows Vista/7.
Whenever I use it to install Ubuntu (done it a few times now) or as a LiveUSB to try and rescue my installation, it never shuts down or reboots. It just starts the cycle then hangs on the white Ubuntu logo. As it never gets past this, I'm forced to hard power off, and I'm concerned this could be damaging my mounted system drives? I've decided I should be unmounting before I try and shut it down now, is there a proper way to do this, and can I fix the LiveUSB itself?

I have had a serious problem with my laptop recently. I have been having unexpected reboots and kernel panics and I don't know why. I can't tell if it is hardware or software, and what is causing it.
It has happened on multiple power bricks from different outlets and locations, my slice battery and my main 9-cell battery.
I am running Debian Testing/Stretch with Kernel 4.1 with XFCE4 on a Lenovo T420 with 16 gb of ram, a i5-2540m, USB3 Express Card, OCZ SSD, an intel 7260 ac wifi card and Ericcson F5521GW 3g card. I also have a modded bios for the wireless cards, and I have had that for over half a year without any problems.
I have no clue what the cause is from the logs.
I also booted into Windows for a bit, then it blue screened, but I don't know if it was because of a driver I had tried to put on earlier for the 3g card, because Linux was out of commission and I needed 3g. The driver didn't work, gave a code 10 or something and gave me a blue screen that said something along the lines of device driver attempting to corrupt the system has been caught. Windows also won't boot anymore.
I'm not worried about Windows though, and what I really need is Linux to work, being that this was the first time I booted up into windows in several months.
Memtest runs fine, and passes all tests.
Right when I turned on my computer after one incident, I wrote a script to check the CPU temp and write it to a file every second. Once the computer turned off, I read the file and it said the CPU was at 39 degrees. Not something to turn off over.
I cannot find any indication of a problem in /var/log/kern.log. kern.log was extracted from the computer right after it rebooted randomly. Find it here: [URL] ...

I have recently upgraded to the 10.04 Alpha and have been unable to reboot or shutdown. I know it's just an alpha and therefore problems are bound to exist, so I tried reinstalling from a live cd of Alpha 3. But I am still unable to reboot or shutdown.To clarify what happens, I click on shutdown or reboot, the pop-up appears, I click on the shutdown/reboot button and it seems to complete it. It says that processes have been killed and something has exited with 255. But my computer is still on. I am guessing that Ubuntu is shutting down, it's just not actually shutting my computer down or restarting it.

I have a remote server (Xubuntu 10.04) which suffered an electricity brownout yesterday. The server itself is backed with an ups, but it is connected to a external firewire disk, which is not, and this disk malfunctioned as a result of the brownout.
The problem: Now, any process trying to access the external disk freezes and ends up in eternal D state in the process list, including ls and umount. Even trying to ls a directory which contains a symbolic link to a file in that drive just causes ls to freeze. These processes cannot be killed even with SIGKILL, so I proceeded to reboot but...
None of the reboot commands work. Instead they just get added to the ever increasing list of D state processes. I tried (sudo) shutdown -r now, reboot -f now and finally plain shutdown -h now. Is there anything else to try other than ask somebody to actually go to the server and pull the plug (which is not at all trivial)? Some way to tell kernel not to worry about messing stuff up, and just reboot?

we've just bought 30 newest nettops ACER Aspire R3700 with ION 2. I've tried ubuntu, kubuntu, xubuntu. Everything works as expected, but... the first one freezes when trying to reboot, shutdown or enter sleep mode. Checked on several hardware units. The desktop just freezes and nothing happens (ubuntu 10.10, both x32 and amd64). Also no one installs the wi-fi drivers, only ethernet

Natty won't shutdown for me - the start up/shutting down graphic comes up and the 'light' go down from 5 to 3 then it just hangs there.
Is there a shutdown log? I've looked in /var/log/messages but there's nothing relevant there.

From a 11.04 Ubuntu, I installed the meta-package xfce4 (*). Now, in the xfce4 session, "suspend" and "logout" (from the xfce4-panel button) works, but "shutdowmn" and "reboot" not, they only lead to GDM. (the shutdowm option there works.)
I tried to solve that by installing the meta-package "xubuntu-desktop" (maybe there are some necessary settings included?), and in fact, the login-screen changed (it's still GDM, I suppose) and there is now a "xubuntu" session, but in that, the probem is just the same: shutdown only leads to the login screen.
In Gnome Classic or Unity, shutdowmn works as it shoulds, so it's not a general problem with my computer.
In Detail, in forst tried to install xfce4 with ubuntu-software-center, but although it seemed to succeed, there was no xfce session. In Synaptic, installing the xfce3 metapackage worked. In fact, software-center seemed to have overlooked some dependencies...

i searched the forum about this subject, i found many post but nothing useful. i also wonder why a normal user is not prompted to authenticate as root to perform these tasks. i thought the file /etc/sudoers but i don't think this is the point. i tried the group "shutdown" but does not exist. i read that this is expected in ubuntu server so it should exist even in the desktop version, i guess.

I have an mysql innodb ~ 20gigs. Normally shutting down mysql (service mysql stop) takes a few seconds. When I reboot Ubuntu with the reboot or shutdown command it just reboots it super fast without mysql logging (/usr/sbin/mysqld: Shutdown complete) Also during this shutdown the following is failed: umount2: device or resource busy /data: device is busy.
mysql is setup to read from /data . Why is ubuntu not waiting for mysql to properly shutdown before unmounting the filesystem and rebooting?

I am facing the issue that the PC not capable to shutdown or reboot; In order to debug that, htop tells me the running processes but all seems normal, I killed few but still cold reset is needed.There is certainly a problem somewhere. the best would be to know which process are weirdly hanging. It could make this testing debian bit better to know which package has these issues.

Two or three times on a daily basis it just freezes and I do not know why. For example, I am doing some minor coding, surfing the web and just some regular stuff and suddenly, out of nowhere, it just freezes. I cannot force reboot, cannot shutdown, cannot run, cannot enter terminal, nothing. Totally helpless. Only physical reboot do the work. Never had this issue before.

Recently I installed Fedora 12 64bit in my HP Compaq 6720s. Among many other problems that I had and I solved with your help, I have the following problem:When I restart or shut-down Fedora 12 it crushes and hangs and only thing that I can do is to stop and restart my laptop by means of ON/OFF button.My question is:Is there any way to see this error (maybe some log file or something) so I can send this message or log file here in this forum and get some help?

I hoping someone can point me in a direction. I installed F13 KDE from the live cd and now when I Shutdown or Reboot, it takes 2 minutes and 8 seconds for the machine to power off. Yes, I timed it.Happens everytime like that. Even when booting from both "mainstream" live cd and the KDE spin live cd. When I hit the Shutdown or Reboot, it goes through the daemons/services shutdown the flashes up the Halting System or Please wait while the system reboots messages (respectivley), turns off the LCD and then just... sits with the power light on and hard drive activity light on. I should mention this is on a Toshiba Laptop about 2 years old now. Intel Chipsets. (Satellite Pro S300M-S2142 if anyone is really curious). The hard drive light stays on for about 1:03 minutes and then it turns off, at 2:08 minutes - the Power light finally turns off and the thing finally shuts down or reboots. If this sounds familiar, it's because it is and I've posted about it with F12 and it's still there with F13. Running kernel-2.6.33.3-85.fc13.x86_64

After a couple of days, some commands related to the disk (df) or files (ls) or killing process (kill -9) doesn't respond. Even I can't reboot or shutdown my server. After an hard reboot, some files are not here anymore or the log files are not filled anymore until I restart.My disk are behind the RAID controller i6 and are configure in RAID 1. The disks are two HP SCSI 72,8GB 10k RPM.Maybe I am totally wrong to check the disk access side, so I am open to other explanation.I can also add that my CPU is running under 1% et my RAM under 10%.

I don't follow why the Suspend option is there and the Reboot and Shutdown is not. Can anyone guide me to the code needed to add the selections. I know I can use a Terminal to shutdown or reboot but a simpler solution would be nice. I expect there are methods to fix most of what I don't like about Gnome 3 but I haven't found them yet. Is there a central place for the solutions needed to deminimalize Gnome 3? I really prefer one click control.

A couple of little niggles seen with KDE4.6. On 32bit install, (openSUSE11.3 was clean install)
-- reboot and shut down do nothing but hibernate and sleep are ok, can only powerdown with su privileges,
-- order of applications in plasma bar change after reboot.
On 64bit install, (openSUSE11.3 was update of openSUSE11.2)
-- slow poweroff overcome with new user profile, (no longer a problem with latest update)
-- inconsistent mouse curser theme, over desktop theme is Oxygen White, over application windows its DMZ
(resolved mouse cursor theme issue on 64bit install.
-- /etc/sysconfig, parameter X_MOUSE_CURSOR="DMZ"
-- and
-- /usr/share/icons/default was a link to DMZ
-- /usr/share/icons/default.kde4 was a link to oxygen
-- changed so that both were linked to DMZ
-- mouse cursor now consistent within windows and across desktop.
