Hardware :: System Frequently Become Shut Down
Dec 27, 2010
I am using lenny on an Intel 5200 dual core machine with 2 GB RAM
The problem facing is sometimes The dialog box "The sustem will immediately shut down" is shown and goes to power off. I thinks it is connected with a hardware problem. But It is difficult to trace out what is the problem and in which part of the hardware it is.
The motherboard of this computer was complaint and it was replaced by the company (It is seen than it is the same motherboard with one IC replaced)
The problem is difficult to identify since it is not happening every time. When the service persons are here it is working fine. But when i works with the computer seriously, the problem arises - mostly in night. I have checked the power, voltage etc - everything fine. Also it is in linux, service persons don't pay attentions to solve the problem.
Is it the problem with RAM? It is a new RAM. Even if it is bad I can't replace it because it is working! and in windows (service persons check it with windows only)

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

I am running FC12 64bit. Frequently the system hangs usually one app - Thunderbird. If I have Firefox up also, it seems to run fine. The light indicating disk access is on almost constantly. Is there a way to find out what process is accessing which disk? I have 4 hds installed - 2 IDE and 2 SATA. I am having a similar problem trying to do a reboot - it does not reboot within 15 minutes. I need to hit the reset button.

The system frequently freezes the screen. The mouse is still moveable but there is no reaction on any click. Keyboard does not work either (pushing Num-Lock does not toggle the Num-Lock light on the keyboard). However, Alt-Print-b works for a reboot. The only other way out is to turn of the computer.I had this effect some time ago where I thought it was a problem due to the NVIDIA graphics driver. Since then, I changed back to the standard VESA driver and thought the problem would be gone. Just a thought
I toggled through the log files in /var/log which had the file date/time of the crash but I could not find any hint.Which log files could I look as well to dig for the problem? Or any idea for such an effect?

I had installed Fedora 12. Initially it used to work fine. But then, every morning I start it, the system hangs after booting, I could only get a stable session after 2-3 reboots. This regularly happened and one fine morning, my system finally crashed. What could be the reason? Should I re-install F-12

I recently installed centos 5.5 on a new system, details below. All worked fine for a couple of weeks, then the system froze up. No network access, no keyboard/mouse, blank screen. Had to reboot. Happened again about a week later. Then started happening every couple of days, then daily, and today it happened three times.
I see nothing unusual in any of the logs. The freezing does not seem to be correlated with any particular activity. Happened in both gnome and kde. While it's up, everything seems to work fine. I looked on the intel site for a new driver for this chipset but didn't find a linux version. I tried different versions of this same kernel (PAE, centosplus etc) but have not tried an older kernel.
I installed memtest86 (with yum) but when I try to start it from grub, the screen goes blank for a few seconds, then it reboots. Can't get it to start. Tried a bootable memtest86 cd that worked before (couple of years ago) and it wouldn't boot from it (bios is set to boot first from cd). Maybe this is a strong hint?
My next steps are to burn a new cd of memtest86 and try that. And/or to start removing ram to see if any of them are the culprit. In the meantime I'm asking if any of you have had similar problems with this architecture, or have other suggestions of things I could try. I don't have pieces of hardware lying around that I can easily swap in and out, unfortunately. If all this fails I'll try FC13. Any advice on whether or not you think that might fix the problem would be appreciated, before I go to the trouble.code...

I am experiencing an issue with the system shut down.
Everything works fine, but the system is not able to automatically power off and I have to manually switch it off.
How could I fix this behavior?

My system just shut itself down as I was using it. I'd like to try to understand why.
First, I noticed there are 1 to 4 messages per second in my messages.1 through messages.4 files in /var/log going back to September 27. It probably started before then, but I don't have older logs.
There almost nothing else in the messages log but these messages, millions of them. They look like these:
Quote:
Then just before shutdown, there are a few dozens of these:
Quote:
And then right at the end, a switch to runlevel 0. I did not initiate that. Something else did. And finally a dbus-daemon segfault.
Quote:
What other logs can I look at?

I just installed 11.3 and Gnome yesterday and all went well except that the system will not shut down, it simply reboots. I've tried shutting it down using halt and shutdown now as root and each time the machine reboots. I didn't have this problem with 11.1.

I have an online server which I can not reach any more !
Code:
normally works just fine but now there is a timeout...
Code:
Status of csf:csf and lfd have been disabled, use 'csf -e' to enable Status of lfd:lfd is stopped. The only thing I have is a management-interface with a command prompt(luckily !) You can see that any firewall is disabled.
Still I can not reach my server. Not through webmin via the public address, not through the VPN on the private address (10.10.0.1). So no webmin. I cannot reach my server via ssh. I cannot ping my server on the public IP-address from my client.
What else besides the firewall can restrict my access to my server ?

So I've got a backup server that has a daily cronjob to back up all my systems. My desktop PC is usually in sleep mode to save power. So my backup server has to wake up the desktop via wake-on-LAN to start the backup job. When the backup script is done, my backup server sends a shutdown command to the desktop to put it back in sleep mode.
The trouble is that SSH is timing out during the shutdown process and waits a ridiculous amount of time before giving up and allowing my backup server to move on to the next backup script. Here's the portion of my backup script for the desktop that does the shutdown stuff:
Code:
ssh user@host.lan '/usr/bin/shutdown -p +1'
Here's what cron sends me via e-mail:
Code:
Read from remote host host.lan: Connection timed out
real 164m46.280s
user 5m16.160s
sys 1m39.760s
Normally the entire backup job will only take about 5 minutes. But because of SSH timing out, it takes 164 minutes!
As a matter of detail, my backup server is running Ubuntu 9.10, and the desktop is Windows 7 x64 with Cygwin. The -p option for the shutdown command in Cygwin is for sleep mode.

If I click on the shutdown bottom (in my lower panel) I get an new window to choose if I really want to shut down or restart or suspend or hibernate. Under that alternatives there is an text that says: "[...] The system will automatically shut down in 60 seconds." Why is the text "60" not running down like a countdown? Can I set another (shorter) time for the automatic shutdown (10 seconds)? If so, where? Or shut I just make another bottom to shut down immediately?
I use (normally) OpenSuse/SUSE Linux
Release 11.1
Kernel Linux 2.6.27.45-0.1-pae
Gnome 2.24.1

Using the ubuntu live cd 9.10 I get weird error messages when shutting down the system, sometimes it is this one:
device removed: /freedesktop/Hal/devices/net_80_00_60_0f_e8_00
Other times it is bunch of errors saying something like:
i/o error/end request/dev/sector ****, with all different sector numbers..
These happens even when I have not installed anything, not using any flash drives etc...

I have a flash drive that I regularly use on my laptop. If I unplug the flash drive without first unmounting it, I get a popup notification of a kernel failure (with diagnostics sent to kerneloops.org). Then, if I attempt to shut down the system via the console, it hangs on "The system is going down for halt/reboot NOW!" and doesn't actually shut down. Using Gnome's graphical System > Shut Down feature just logs me out and sends me to the login screen; the shutdown feature from there does nothing. I have to disconnect the power cord on the laptop in order to shut it down, and I don't like doing this.
System: 32-bit Debian Squeeze stable with kernel version 2.6.32-5-686, running Gnome 2.30.2, on an Acer Aspire 5570z.
I use Keepassx to store my passwords and keep the keyfile for my password database on the flash drive in question. I mention this just in case it helps determine what's causing the failure.
dmesg has quite a bit to say about this:

I recently switched from fedora 14 to 15. Today my computer suddenly shut down during an update, as I thought it overheated I decided to clean the cooling system and reapply thermal paste. However, now the system won't boot anymore ("kernel panic - not syncing : VFS: unable to mount root FS on unknown-block").
I would like to either solve this booting problem, or mount the fedora 15 filesystem and recover some files. Whichever is easier.
I have another drive with fedora 14 (antec below) which boots fine:

Anywhere from 2 -> 6 times a day, my computer will freeze up. If any audio was playing, it will repeat the last few seconds over and over again.
I've been dealing with the problem for a couple of months now, with no solutions.
It can happen anytime, but it tends to happen on my screensaver about 50% of the time after I've locked my computer and during the early morning (12am onwards) when I have a full-screen video playing, but it's never done it at night in the same circumstances.
I am confused and just can't figure out the problem.
Computer info:
Mac Mini (2010) 2.4GHz
8GB RAM
Dual 24" Monitors @ 1920x1080.
Ubuntu 11.04 64-bit.

I just upgraded to Natty on a (almost brand new) HP pavilion dm4t. I'm finding that it crashes pretty frequently, in a variety of ways that might or might not be related.
1) Sometimes (every 2-3 days) it will just blink out and go back to the login screen. This usually happens within a minute or so of logging in. If I log in again after this, it will usually crash again. A restart of the system typically will make the problem go away for at least a few sessions.
2) If I leave the computer on for a while, the screensaver will freeze and nothing can get me back to the desktop. Processes seem to still be running behind it (I left some music playing once and the music continued to play, but the screen was black and I couldn't get back to my desktop - I had to do a hard shutdown)
3) A perhaps unrelated problem, every ten sessions or so when I log in the indicator applet will be gone and an error telling me that indicator applet failed to load (or something to this effect)
Btw I'm using ubuntu classic rather than unity (just because I like it better). I haven't used Unity enough to know whether these problems also occur with it.

I started using 10.10 a few months ago and had very few problems aside from a few minor issues with Wine. I frequently used Skype under 10.10 and it ran perfectly with no issues whatsoever.
Recently I upgraded to Ubuntu 11.04 and well... basically things have just gone downhill from there.
Over the past few days Skype has been ridiculously unstable, I'll be talking to somebody using text chat and it will essentially freeze up. These freezes can occur within minutes of starting Skype and are very infuriating. I am still able to type and send messages but the "message not sent" icon will appear next to each of them and the timestamp on each message will be identical (the messages in question will not send even after a restart of Skype). This problem will persist until I force-quit the application, closing it normally will not work and often I have to restart my computer entirely before it will work again.
I have tried updating to the latest version of Skype to no avail (if anything I think it has made matters worse, but that may just be my imagination.)
I'm not particularly command savvy, just posting on the off chance that anybody has encountered the same problem or has found a relatively simple fix. I don't really want to have to re-install the entire OS just to roll back to 10.10.

I'm using Ubuntu 6.06 and Apache.I connect to the machine via FTP. It seems as if the connection times out every few seconds. If I u/l a file it will take 15 seconds to connect. Once that connection is open I can u/l more files instantly. If I wait a few seconds it closes, then I have to wait another 15 seconds for it to reopen. Any ideas how to make it not time out so frequently?

I'm looking at conky and my cpu frequency is fluctuating really fast (in a relatively narrow range) but from second to second I can see a 2-3 degree change, is this even possible? It seems like the sensors aren't working right if they are showing changes that fast.

Recently pcmanfm crashes more frequently then before. Each time it occurs, I cannot open another instance of it until I reboot my desktop/laptop. But this is not possible if I happen to be doing some long computational work. I have been using it with fluxbox for two years already, and previously I simply reopen another new window and get on with my work.
