CentOS 5 Hardware :: Shutdown -h Reboots The System
Jan 3, 2010
I have a newly installed CentOS 5.4 which is having shutdown problem, if I try "shutdown -h now", the machine will poweroff then reboot instead of poweroff completely. how to debug this problem?
Hardware: Gigabyte G31M-ES2L, 4G RAM, Sil 3112A PCI SATA card, 6 SATA disks and one IDE disk. I have disabled all power on options in BIOS.
Software: CentOS 5.4, software RAID, samba
"cat /var/log/messages | grep ACPI" shows:
Jan 3 11:20:43 filesvr1 kernel: BIOS-e820: 00000000bf5e0000 - 00000000bf5e3000 (ACPI NVS)
Jan 3 11:20:43 filesvr1 kernel: BIOS-e820: 00000000bf5e3000 - 00000000bf5f0000 (ACPI data)

Running CentOS 5.5 on a Dell PowerEdge 710 with a mirrored RAID. System randomly reboots leading to MySQL table corruption as its not a graceful shutdown. Here is the output of the getinfo shell script [URL]. Some data has been obfuscated such as public ip addresses. Prior to posting this a full hardware diagnostic was run by the Data Centers support team which turned up nothing.

I've been googling my brains out looking for a solution to this. So far, nothing.
As the title suggests, every time I attempt to shut the computer down it instantly reboots the moment the internal fans stop whirring.
So far I've tried:
-shutting down via the terminal (this actually makes the reboot happen instantly rather than waiting for the fans to stop)
-looking in the BIOS for any obvious settings which may be causing this
-performing a dpkg repair
-Allowing "Proposed" updates in the Updater
-installing (slightly) older Kernel (2.6.35-22 as opposed to 2.6.35-23)
-installing newer (2.6.36) kernel
I know others are having this issue, but other threads I've read seem to have fizzled out with no conclusion. Has anyone managed to find a way to make this work if they've had the bug?
Any advice at all? Is it worth trying an even older kernel? Or an even older version of Linux?

If I issue a shutdown -rF now, it will force e2fsck's on all the volumes when it reboots. But once the checks automatically finish, does it restart normally? I want to run e2fsck's on all my volumes, but dont want to stay the probably 5 hours it will run, so hoping someone knows for sure what happens.

I am trying to set up a somewhat older Dell as a test box. I installed Fedora 13 on it. When I attempt to shut down the system, it reboots and powers back on. I have attempted shutdown using the GUI, and variations of shutdown, init and halt. All of these result in the PC powering back on. The only way for me to power off the system is to press and hold the power button.

unclean shutdowns/reboots. Whenever I boot/restart, I notice the message "/dev/hdb1 (and hdb2) was not cleanly unmounted, check forced." Then fsck(?) scans them without errors, and everything continues normally. FWIW, hdb1 @ hdb2 are ext2, /boot & /tmp respectively, whereas all other partitions are ext3. Could that (ext2) be why? I checked halt, reboot, umountfs, umountnfs.sh, and umountroot in /etc/init.d, and nothing jumped out at me, though I'm not exactly sure what I'm looking at/for.

I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I have is when shutting down (*not* rebooting). NetworkManager fails to stop and after (during?) the postfix shutdown, the system seems to hang.I cannot access via another screen or remotely. I can't find any clues in the log files.

I have used ubuntu 8.04 in a dual boot system together with windows xp and wanted to upgrade to ubuntu 10.04.
Since the upgrade did not work (the usr partition was to small and I couldn't make it big enough) I downloaded the ubuntu-10.04-desktop-i386 edition and tried to install it.
Everything worked find during the installation process but when I tried to start ubuntu I could only see the ubuntu desktop for a second and then the computer began to reboot.
Then I thought that I can solve this problem by installing ubuntu 8.04.4 again and trying to upgrade to ubuntu 10.04.
After the installation I could start ubuntu 8.04.4 without problems but after upgrading to ubuntu 10.04 the same problem occurs again: ubuntu 10.04 causes the computer to reboot every time I try to start ubuntu.

I am fairly new to linux.We have a machine running CentOS 4.4 and sometimes the machine has to be rebooted. Each time after the reboot, I have to SSH in and manually restart one of our application. I have been reading about doing this online and I am a little confuse.Seems like there are multiple possibilities for starting things up. My finding suggest using the inittab file. Then my question is what runlevel do I pass in? Should I use runlevel 1, 2, 3, or 5? Once the runlevel is determine, then how should I name my startup script? I know to use "S" but what number should I give it? Or, another way to approach this is to put my autostart script in the /etc/rc.local file?

I received a new Cyberpower CP1000PFCLCD UPS today. I let it charge for about 6 hours.My server is a former desktop PC with the following specs:MSI MotherboardAMD Athlon XP 2000+ CPU768 MB DDR RAMDual 80 GB HDD running RAID 1 (Disk Mirroring)After shutting the server, router, and backup drive down and plugging in the UPS, I did the UNPLUG test where you unplug the UPS to see if everything stays on.My Router and Backup disk both stayed powered on, but the Server immediately rebooted.Does anybody have any ideas how I can fix the server rebooting problem? It should be staying on just as everything else.

Last night I rebooted my desktop and it failed as in it just kept resetting after the bios post...so I changed my boot drive which gave me a "no bootable drive found" error(this confirms hdd fault) thee I booted a live cd and checked my partitions
They are as follows
sda1 - boot(ntfs)
sda2 - windows(ntfs)
sda3 - swap
sda4 - ubuntu(ext4)
I tried to mount sda4 to reinstall grub but it failed...says the partition is corrupt sda2 has no problems and I made a backup for it now the problem is how do I perform a disk check on sda4 and how do I get my system up and running again? I dont want to reinstall!

I've found a workaround, but the workaround doesn't make any sense to me.I suspect I am running into a bug of some sort.I've tried to search for a solution, but the search terms are too broad and I can't seem to find anything useful.I have a CentOS 5.5 system that I've set up Virtualization on (presumably Xen, right?). I have a RHEL 5.4 Guest OS using "Full Virtualization" method.When I was installing the RHEL guest, the entire server rebooted just as the RHEL guest was booting for the first time.Thinking that odd, but coincidental, I just let the Host server reboot and then started up the RHEL Guest again.The reboot happened again and in the same spot! When I say the server rebooted, I mean black screen...pause...bios screen.I finally managed to get the RHEL Guest booted by removing the DVD that I had in the DVD drive and disconnecting it from the Guest OS in VMM. Very, very odd. I can reproduce this behavior by simply booting a Guest OS with a DVD in the drive (so far I've tried only RHEL guests).
The reboot happens at the same place in the Guest boot process. It's when RHEL starts the UDEV script. Actually, a few seconds after the RHEL system displays "Starting udev" message. I've looked in both the CentOS and RHEL messages log and found nothing.It's not a huge deal at this moment, but I will be sending these servers out into the field and I can't control what the end users of these systems put in the DVD drives.

I've got a computer i'm trying to VNC to.
The problem is that when the computer starts up/reboots it doesn't "Unlock the system keyring"(I think that's what it said).
When I try and attempt to connect to the computer it asks for the VNC password(as per normal) but fails to connect after that.
The reason is that the Ubuntu computer prompts for the user's password to unlock the system(locally).
What I want is to be able to turn on the computer without having to worry about entering the password. I've had it running fine on 8.04 yet the newer version seems to be annoying :s
The system is set to automatically login on startup too.
I've tried this: "delete the keyring folder under /home/XXXX/.gnome2" then setup remote desktop again. But that hasn't worked either. I still have to enter the password to a keyring

I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.
Only options selected for install where 'server' and 'server gui'.
Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):
root (hd1,0)
kernel /vmlinuz-2.6.18-238.e15 ro root=/dev/VolGroup00/LogVol00 rhgb initrd /initrd-2.6.18-238.e15.img

I have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:
/etc/sysconfig/network-script/ifcfg-eth0
/etc/sysconfig/network-script/ifcfg-eth1
/etc/sysconfig/network-script/ifcfg-eth2[code]...
Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.
This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.
Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.

I currently run kernel 2.6.34.7-66.fc13.i686 (sort of). When I select from the Gnome menu System -> Shutdown and select Shutdown from the dialog, my system only logs out, presenting me with the greeting screen. While this is a minor problem and I rarely shutdown my machine, it is mildly disconcerting.I have dropped back to 2.6.34.7-63.fc13.i686 and that shutdowns properly using this method. (Also, 2.6.34.7-61.fc13.i686 works properly). I can imagine that it might close some security issue in which an unauthorized user is able to halt the entire machine. Especially if this is something that will continue in future releases of the kernel.

From couple of mins my system shutdowned without my permission I thought I'm infected or something because I installed aMSN so I thought it's because of it, but I checked my syslog and found this:

Temperature reached is that what cause system halt? Also when I press ctrl+alt+Fn I see blank screen why is that?

after installing linux mint 7, I have been getting one beep on shutdown, a google search on this came back as a ram problem...but then i ran across a bunch of posts on ubuntu forums about one beep on shutdown, with an older version of ubuntu, grep does return some paramter errors, but in the mint bug report page those are listed as : benign ignore. it doen't bother me in the least, as long as it isn't a warning of impending hardware failure.

I'm running Ubuntu 10.04, and I like to logout or shutdown or restart my system with system->shutdown just as in Fedora, but it's not there. How can I add this, the only way that I have been using is through the terminal or Crtl-Alt-D, which doesn't has Logout option but Hibernate.

Tested on RedHat entreprise 5.5, 5.4, 5.3 I would like to stop my db (not oracle) when the system shutdown or reboot. I have wrote my script for init.d
Here is the head :
The problem is : shutdown -r stop the system before my K script execute. I have not my "blabla" in /tmp/mystop.log
In fact the scritp is for database startup and database shutdown manually it works I mean : /etc/init.d/mystop stop ; /etc/init.d/mystop start So I truncated the scritp until I only get echo "blabla"
This work idealy under HPUX, AIX, and I think I'm missing something "special" for Redhat. I'm quite sure it was ok with redhat 8 and ES 3.0.

I am running Debian Squeeze on an Intel DH55TC motherboard. When I issue a shutdown command
shutdown -h now
The system goes shutting down. Eveything looks fine, and the main console shows all process being stopped. In the end it says "System will now halt". Then a few seconds later, it restarts. It is unclear what is causing this, because nothing is written to the screen. It just goes blank and starts rebooting. Looking afterwards in syslog doesn't show anything also.

I've just installed F15 KDE Edition, and as the title tells, I need to keep pressing F2 and/or Enter to make the system go through the boot up process, otherwise it freezes as long as i keep it without my interference !! and then it takes relatively long time to start the GUI, and when I switch to the console (using ALT + CTRL + F3 for example) and try to write the login or the password, there seem to be some 'bouncing' effect, that if I'm to write the login 'root', I get something like 'rrooott' ... however, this doesn't happen in the GUI .....
I have a multiboot system, with Windows7 and Linux Mint (based on ubuntu 10.4) installed along side. While Windows7 doesn't have any problem with my hardware, Linux mint has also some issues that cause the performance of media players to degrade (sound and video tearing) and cause repeated freezes to some applications (a game actually, 'wesnoth') until I press a key or move the mouse.
I have AMD Athlon 7750 dual core 2.7 GHz system, with 3GB DDR2 800 Ram, and embedded ATI Radeon HD 3200 with about 512 shared memory.
one more thing, when I booted off the live image to run the install program, I booted into the video failsafe mode (not sure of the exact name, but I think you got it, no mode setting) and passed the option 'noapic', so I suppose this options are still passed whenever I boot mysystem, as I get the text version of the progress bar during startup, rather then the graphical fedora logo ( i.e no mode setting) ..
