Software :: Sudden Shutdown/poweroff -- No, It's Not Bad Hardware Or Dirty Fans?
Nov 9, 2010
I just did a clean reinstall of Ubuntu (10.04 --> 10.10). After the install, any time I do CPU intensive work, my PC is suddenly shutting down like it's overheating.Everything was working fine for months, and started having problems immediately after the reinstall. so this is not a problem with my hardware, and it's not a problem with my fans needing cleaning -- it's a problem with software. So please don't tell me "that sounds like overheating, clean your fans". Something is different in software-land between 10.04 and 10.10 that is causing this to happen -- I assure you that the upgrade did not magically fill my fans with cat hair.
I have checked my log files, and can't find anything related to overheating -- searches for things related to lm_sensors, "temp", and "thermal" are not turning up anything in the system logs (syslog, kern.log, or messages). I also looked at the logs around the times of the sudden shutdown, and couldn't find anything unusual.How can I diagnose this? I'd like to file a bug report, but since I can't find anything in the logs, I honestly have no idea how to go about providing useful information.Is there anything besides overheating that might be causing my laptop to suddenly shut off?

I have a server Hp proliant DL160 G6 with CentOS 5.4 . When I do shutdown -h now it doesn't poweroff.
I try differents options for acpi in menu.lst file. acpi=force, acpi=noacpi,acpi=off,acpi=ht but there's the same problem.
This the stdout when I do shutdown:
Halting system...
md: stopping all md devices.
Completed flushing cache on controller 0
ACPI: PCI interrupt for device 0000:05:00.1 disabled
xenbr0: port 2(peth0) entering disabled state
ACPI: PCI interrupt for device 0000:05:00.1 disabled
Power down.
acpi_power_off called
I show you any specific information about my server:
Reboot works fine

Built new system and installed openSUSE 11.3 x86_64 with Gnome desktop about 6 weeks ago. Have never been able to get the system to shutdown or fully poweroff using the installed OS. If I use the Knoppix live CD - no problem. System boots up fine and shuts down and powers off correctly. With the installed OS, it originally crashed on shutdown and had to power off using the power button. After trying many things, the OS shuts down, powers off the fans etc, but the keyboard is still lit. I cannot restart the system without turning off power at the power supply. Starting my computer by turning off the power supply switch, waiting
10-12 seconds, turning on the power supply switch and then hitting the power button gets to be very annoying after a few weeks.
Installed KDE and switched to that to see what difference it might make. System does not shutdown, but reboots instead. Switched back to Gnome. Have tried sudo /sbin/shutdown -h now and poweroff. Identical behaviour. System is completely up-to-date. BIOS, kernel, video drivers.

I run Ubuntu 10.04 on a HP dv2000 laptop with 2GB RAM. I see a strange problem with my system. When running on battery and the level hits about 43% (+- 1%), the system shuts down suddenly. No warning and no information in logs either. Temperature of both cores are below 50 C. I have tried cleaning the dust withing the laptop chasis but no progress.
I have done quite some research on this and other forums but haven't found anybody else with similar problem.

I have an user space application that performs file I/O operations, when a SIGKILL is captured, some routines are done first to ensure that all I/O operations are completed before rebooting the application or system. My question is, this won't work if the power button is pressed or the power supply is disconnected, so there can be incomplete I/O operation or corrupted data written into the file, so is there a way to prevent data corruption or at least complete any ongoing operation when this scenario happens? Assuming there is at most 1 second before the power really went out, can I/O be still completed?' I'm running the application on a busybox 2.6.14 kernel on an embedded system board.

A new open source package called Lightning Rod will help to close security exploits in Adobe's dirty Flash code. A presentation made at the 26th Chaos Communication Congress showed that the package does its job by reviewing incoming code before the browser executes it. Heise Online is reporting that this method can block over 20 different known attacks and can even be used to filter out malicious JPG attacks. As more vulnerabilities are discovered they can be added to Lightning Rod to close the breach.

I have a server that has 2 dirty volumes, both of which are very large. One volume contains live data, the other is just a rsync'd copy of that data, which isn't critical to the users. The e2fsck is taking forever in single user mode, so i'm wondering if there is a way after the volume with live data becomes clean from e2fsck fixing everything, if i can boot the server and have it skip mounting the other dirty volume (/dev/md1) just this once, so i can get the server up with the live data available to users. Then with /dev/md1 unmounted with the server up, I should be able to e2fsck that until it comes back clean, then do a mount /dev/md1,Please let me know how I could do this, I'm running RedHat if that matters. I'm quickly running out of time here,

So i've been using poweroff command to shutdown my computer at a specific hour.
Is it okay for the hardware to do this (e.g hard drives)? Or should I use other system call?

my computer sounds as if I have been playing crysis warhead for like 5 hours, because every fan in my computer is running including the graphics card. They are not just running normal either they are running at the max.

i'm using slackware 13.37. (Sony Vaio VGN-FS315H)
my fans are working all the time, they are loud and it's annoying.
I already did sensors-detect, but I get this message every time.
Code:
Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.

I recently upgraded the hard drive on my Fujitsu N3530 notebook to WD Scorpio Blue 500 MB, and created a dual-boot configuration with WinXP, installing 32-bit Slackware 13.1 from DVD. Grub 0.97 bootloader is installed on superblock of root partition. Running KDE. Using the generic kernel with appropriate initrd for ext4 filesystem on root partition.
Everything runs fine so far, except the computer won't power off the computer. I've tried using the KDE shutdown, and shutting down from command line - same result. Also same result if I use the huge kernel or the generic kernel.
The last message I see is:
Remounting root filesystem read-only.
/dev/sda3 on / type ext4 (ro)
Power down.
... and then the shutdown process stalls and I have to turn off the computer by pressing and holding the power button.
This is the first time I've installed any Linux OS on this notebook. I have Slackware 13.0 running fine on a Thinkpad T61 with no poweroff issue.
From reading various posts, this looks to be related to ACPI. I tried adding "acpi=force" to the kernel line in menu.lst, but it made no difference.
/var/log/messages shows "acpid exiting" and then "exiting on signal 15" as last entries during shutdown.s.

I have problem with funs speed in my fujitsu rx100 s6 server, rpm funs is 3000 ? I think it is not standard speed funs. On windows 2008 server funs works quietly. Fujitsu supports only windows servers, red-hat enterp. and suse enterp. Is there any software to control speed fans?

I am trying to use GKrellM [URL].. to monitor my system's fans/temperatures (I am trying to undervolt the fans a bit to make the systems quieter), but there don't seem to be any sensors available. I have lm_sensors installed.

I'm finally making the change away from rhythmbox for the now adopted Banshee and I'm noticing that my fans run really hard when I'm running banshee. I'm monitoring speeds and don't notice a huge increase in temp but the fans none the less run hard. CPU usage is running around 6% for banshee not nearly enough to cause this fairly large laptop so having the fans run hard make it a bit loud when around others

I am going to upgrading the cooling in my computer, so I bought 3 case fans (the amount my case has room for). They have 4 pin connectors, so I was just going to plug 2 of them into the 2 available fan headers, and then plug the last one into a molex connector considering that they all come with molex adaptors. However, according to this site, your not supposed to because its too much strain on the motherboard? I am not (never have never will) overclocking so is that just for overclockers? My motherboard manual says it will work with 12 volt fans which are what these are.

After preupgrade downloads install media and reboots to start install, I get a dirty file systems error on /dev/sda2, my / partition.I fsck'd sda1,2,3,4,5,6 (all clean) and rebooted, ran preupgrade again and got same error. No other disks are mounted other than internal SSD.wtf is going on here? ;-)More importantly how does one get around this error? Only half-solution I have found on the net for this problem is to set allowDirty=1 in upgrade.py and recreate install.img. Have no preupgraded before so don't want to take any more risks than necessary.Thanks for any workarounds....---------- Post added at 03:12 PM ---------- Previous post was at 08:31 AM ----------Anyone have ideas here? I'd like to avoid yum upgrading as that looks to entail more pain.Why on earth does Anaconda see my /dev/sda2 on "/" as dirty when fsck reports it as clean

Last night there was a rather large thunderstorm, and my computer was on at the time. The power went out while my computer was on, and now it won't boot up. After the GRUB screen, a white message at the bottom of the normal loading screen says somthing along the lines of "a partition listed in /etc/fstab cannot be mounted /dev/disk/by-uuid/6835blahblahblah". I chose recovery mode from the grub menu, which gave me a similar message.
Quote:
One or more mounts listed in /etc/fstab cannot yet be mounted: (ESC for recovery shell) /home waiting for /dev/disk/by-uuid/8bl I've googled around a fair bit, but people who got the same message were mainly those upgrading to Karmic, so a different problem. I think my problem was the fact that my computer was turned off possibly while writing and definitely without being unmounted.
So far I have tried changing /etc/fstab to refer to /etc/sda5 instead of UUID=68blahblah, but that came up with the same error. I have looked inside the /dev/disk/by-uuid and the disk that is trying to be mounted is there (so it's not a problem with that).

Due to some reason not known to me at this moment, my regular shutdown doesn't work. It freezes on disabling the swap file and doesn't do anything. Now, until that problem is solved, I need a way to properly shutdown. I found one, which is poweroff -f, but it is hardly graceful, and would amount to 'flipping the switch' I guess. The other is hibernate, which is what I now use. This does work, but I rather completely shut down the system. For one, regular boot is quicker than resuming from hibernate.
My main question is: is there any way to make the poweroff -f command, e.g. combined with manually disabling the swap file or whatever,"safe?" as in, I can imagine a sudden power off meaning more chance of damage to the HD, which I don't want.

recently I'va bought PCI adapter for extending ATA devices [URL], connected disk (WDC WD1600JB-00REA0, ATA DISK drive). Everything is fine except switching off. Sometimes it freezes, sometimes it takes longer time (more than 30 sec). Everything goes well - except the last step (when appears "Rebooting", or "Switching off" on console). I didn't add any extra boot option into /boot/grub/menu.lst

I upgraded my Asus Eeepc 900a to 10.4 yesterday. Since then, Xorg has averaged between 30-40% CPU, and my fans have gone nuts running high/low/high/low, ad nausium.
Any ideas what might be going on? Another clue perhaps: on reboot or shutdown, I get a "program not responding" message with "unknown" as the hung program. I have not been able to determine what this program is or if it is related to the hyperactive Xorg.

I have an HP ProLiant DL560 server with Debian 6.0 installed and cannot figure out how to get the fans to run at anything except high. I have searched google and this site, but cannot find anything that works on Debian 6; the SLES packages will install, but don't do anything.
Server Specs:
HP ProLiant DL560
4x Intel Xeon 2.20GHz processors
6GB RAM
2x 72.8GB 15k rpm SCSI HDDs (Raid 1)
2x power supply

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.
