Debian Configuration :: System Freezes Without Any Log Entry
Feb 26, 2011
I have a Dell Latitude E6410 which I can boot from an Iomega external hard drive when I want to run Linux on it. It is a work issued Windows XP laptop and when I travel, I am more comfortable with Linux, so I created a dual boot option without touching their hardware. The external hard drive plugs in to the USB ports and the BIOS picks it up as the primary boot media, although the internal drive is still present. (That is the desired outcome).The problem is that the system periodically locks up solid and only a forced power off will get it to respond. The system seems to go into a kernel panic and fails to write anything before dying. The system completely locks up and stops responding to mouse and keyboard. It also seems to drop off the network. When I look at the logs after restarting, nothing at all shows up related to a kernel panic or anything else. To further complicate the diagnosis, on the reboots, sometimes the boot process locks up at "Starting GDM3", sometimes it doesn't, and wont for several attempts but eventually will boot to gnome. Some times it runs fine for a few hours, sometimes for only a few minutes. Can anyone recommend a way to diagnose this?I am trying to run Debian 6.0 32-bit with the defaults.
Happens on Jessie AMD64 with mate, I can't go to a tty to kill mate system monitor, mouse stop working, keyboard stop working. I tried changing the theme, and now it freeze opening mate system monitor.
We have several systems (DELL-Server PowerEdgde) installed with Debian Jessie 8.4 (physical server and VM) and if the server has big Disk I/O (copy, backup with Backup Exec) the VMs freeze.

The system installed: Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06)
I installed Jessie with ext4 and ext3, same error!
This started happening after I started working on the kernel image and initramfs tools configurations basically started trying to make my system work the way I wanted.I can be doing anything like playing worms or being on this forum and the screen turns black but I don't lose energy just nothing shows on the screen and my keyboard doesn't respond the num lock doesn't turn either state,
After a successful install of the MFC-J4420DW printer and scanner using Brother's install utility, I am experience severe battery drain and xsane freezes (total system lockup, requiring using CONFIG_MAGIC_SYSRQ keyboard command REISUB or hard reset).
The Brother support page and utility/drivers are found here: URl....My laptop is the HP Elitebook 8540W and I am running Debian 8 using LVM, separate partitions for /home, /var, /temp, /swap, and /. I have looked at logs in /var/log. kern.log, daemon.log, messages and dmesg, but have not found any relevant info ...
I purged all drivers/packages and tried a manual install using each deb package, but ran into some permission errors, so I purged again. I also purged xsane and reinstalled it, then did a complete printer reinstall using the brother Driver Install Tool.The tool works great, full functionality for the MFC-J4420DW. But I know I can't live with the power drain, and I would really prefer to use Gimp and the xsane plugin rather than simple scan ..
So it's a beautiful day and I'll be happily using my computer when I realise that the screen is no longer showing that I'm typing or moving my mouse (or finger across a touch-pad). I can leave my computer in this frozen/crashed state for hours. My only recourse is to drain the battery or hold down the power button until the computer shuts down. The computer is a Dell Inspiron 6400 laptop/notebook. As my memory serves, it has an ATI graphics thingy. Radeon 1400, maybe. But I've had the computer for years and this behaviour has emerged only the past couple of months, with seemingly increasing frequency.
The OS is # uname -a Linux polaris 2.6.32-trunk-amd64 #1 SMP Sun Jan 10 22:40:40 UTC 2010 x86_64 GNU/Linux (aka Squeeze?)
Sometimes this happens within minutes of turning the computer on and logging into Gnome. Sometimes this happens only hours after I've started using the computer (mainly just surfing the web). Sometimes it is preceded by a loud boop sound and the following if I have console open, sometimes not. So maybe that's unrelated. But that happened just now so I thought I'd throw it in.
One weird thing: Usually this happens within an hour of starting to use the computer, but one occasion I noticed I had not had the problem for several hours. On that occasion, the only thing I noticed I was doing that was also unusual: I had turned on and forgotten about a kvm virtual machine. After I shut down the vm, I had about only a minute before the freeze. I'm surprised now that it hasn't frozen since I started typing thing. Maybe I should always keep this forum open in a browser window.
I am running testing (with fluxbox) and my keyboard periodically freezes, meaning whatever I type in it doesn't respond. This lasts a few seconds (can be 2-3 or sometimes even more like 10) and one's it comes back I get all the keystrokes I was typing during the freeze. The frequency of the freezes can be like 4-5 times every hour and are very annoying. I can't seem to relate them to anything, they can occur during heavy usage but also when the box is doing absolutely nothing but waiting lazily for me to type some google search terms.
Can anybody help me track this problem down? At the moment I am using a wireless keyboard but this must be unrelated since I tested a couple of other keyboards (both wireless and wired) and the problem persists.
I run an old Toshiba Satellite M35x S114 Laptop with Debian Testing, it always runned smoothly - although it IS testing . Since the latest update to kernel 2.6.32 , the X server just freezes. The init goes all the way to gdm, and then a blank screen , no mouse pointer, no way to get out of this screen (not CTRL+ALT+BACSPACE not CTRL+ALT+F1 / F2 ... etc) just a hard reset.
I can boot to the older .30 kernel with absolutely no problem, gdm starts normally login successfull (as I am able to write this on the reffered machine and all).
Here comes the gory details:
>>> The graphic card: lspci | grep gra 00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) 00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) >>> When it works with .30 kernel: cat /var/log/Xorg.0.log code....
Noting that there are no more Modlines in the new Xorg.0.log
Besides, X is disabling the mouse and keyboard in the configuration.
I've run into an issue that I'm not sure how to address. I'm running Squeeze and upgraded my system this morning.
The packages upgraded were:
About 10 seconds after upgrading, the system froze completely and I had to do a hard restart. The system froze again 10 seconds after the bash login prompt was displayed (I'm not using a display manager) after reboot. The source of the problem appears to be my Realtek 8192SE wireless driver. I was able to boot the kernel in recovery mode and uninstall it, which has fixed the issue. Rebuilding the driver causes the problem again.
I suspect that something to do with the sysv and init packages affected the driver in this way, but I've no idea where to start in trying to fix this. I can't imagine this is a fault of the Realtek driver as it worked just fine up until this point.
I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.
As mentioned in the other two posts, my debian freezes when I use swap. Sometimes only the window-borders dissapear. However, this is not endurable for me. The answer "this is normal" is unfortunatly not getting censored. Even linux must be able to take heavy load without crashing.
Details here: [URL] and here: [URL]
The vlc-problem could be solved by the way: It seems my MESA-installation caused OpenGL to work. As output in vlc, everything runs as it should now.
I've got a problem since I changed from wired to wireless. It doesn't happen repeatably, but usually when more than one application is trying to use the internet connection at the same time (eg iceweasel, icedove, java programs etc). Suddenly, all internet connectivity is lost, and the applications start to hang. Then I can try to close them but they don't close properly and still appear in the ps list. I can pull out the USB dongle (TP-Link TL-WN821N) but nothing responds any more, I can't disconnect using the taskbar icon, and when I try to kill -9 the iceweasel or icedove or java processes, even as root it does nothing.
Eventually the only thing I can think to do is to shut down. Except, when I try to shut down it says it can't stop the avahi daemon, and draws a little tree of the things which are hanging off the avahi daemon (like the apps trying to use the network), and says it can't stop them either. Then it tries to unmount the drives but fails to do that too, and doesn't umount either / or /home. Now the login prompts don't respond any more either (although I can still cycle through non-responsive tty screens), and the only thing left is to hold the finger on the power button.
As the title says, I have tried both of them and they both freeze my system with no apparent reason. They freeze by just looking at them in the fist few minutes after startup and a hard reboot is needed. So I keep coming back to 11.6. Does anyone else have the same problem or is it just my system? By the way I have an HD 6970 in an AMD CPU based system running squeeze. And the reason why I keep installing new drivers and don't stick with 11.6 is a futile hope that anti-aliasing will work with compiz enabled.
I have configured my system to suspend whenever I close the lid, by using the Power Management applet provided by my desktop manager (see my later comment). However, sometimes, when I reopen the lid, I see that the laptop is switched on but it won't resume, while the CPU heats up. I must shutdown forcefully. What could be causing this?
I have found this thread [URL] .... in regard to OpenSUSE. Is it relevant for Debian as well?
System info: - Debian GNU/Linux: 8.1 - Linux Kernel 3.16.0-4-amd64 - MATE desktop 1.8.1 - GNOME Shell 3.14.4
Clarified that the suspend is a user-level setting.
So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.
I have a home server running Debian Wheezy ( 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u6 x86_64 GNU/Linux). I have a Realtek RTL8111/8168B NIC and an Intel 82574L. I saw while searching Google that both cards have this issue. I'm currently using the Realtek card for LAN connectivity. If I try to tranfer large files via SAMBA or have any kind of load on the NIC, my system freezes and requires a reboot in order to restore connectivity. The error message from kern.log is:
Nov 26 02:41:53 golgotha kernel: [ 5178.413329] AMD-Vi: Event logged [IO_PAGE_FAULT device=0a:00.0 domain=0x0021 address=0x0000000000003000 flags=0x0050] Nov 26 02:42:04 golgotha kernel: [ 5188.800088] ------------[ cut here ]------------ Nov 26 02:42:04 golgotha kernel: [ 5188.800100] WARNING: at /build/linux-Tvajqd/linux-3.2.68/net/sched/sch_generic.c:256 dev_watchdog+0xf2/0x151()

Everything runs fine until I try to do a large file tranfer or have multiple users connected.
From time to time system freezes with no particular motive but most often when watching you tube video in full screen mode. How to diagnose freeze, hang, blocking problems in debian jessie system amd 64 gnome 3?
I have an NFS on my desktop, and mount it from my laptop: 192.168.1.22:/mnt/max/share /mnt/reddevil_nfs nfs rsize=8192,wsize=9182,timeo=9 Occasionally, access to the files suddenly "freezes". For example, if I try to run "ls /mnt" from the client, nothing will be printed, Ctrl-c does nothing, and the prompt never reappears; or, if I try to view that directory from thunar, thunar will freeze, or if I am playing a video from the share in mplayer, mplayer will freeze. I tried to unmount it:
umount -f /mnt/reddevil_nfs umount2: Device or resource busy umount.nfs: /mnt/reddevil_nfs: device is busy umount2: Device or resource busy umount.nfs: /mnt/reddevil_nfs: device is busy
I have looked at the GNU GRUB Manual 1.99 at [URL] but I cannot find an explanation of what the kernel entry / command in the grub.conf file means. I get what's the meaning of that entry but where is described what it actually is and what are proper.
I suppose this entry / command was actual in GRUB Legacy, but I cannot find where it is described...
I am building a minimal 6.2.2 linux kernel with slackware on an AMD athlon +1700 single core box.
In the lilo.conf file, there was originally only one entry, which was created by the slackware cd install.
Now, my questions are: 1.Does a person edit the lilo.conf files before or after they rerun lilo?
2. If that person edits the lilo.conf files before they rerun lilo, does the sequence of the entries in the lilo.conf files affect the manner in which lilo treats the new and old kernels? (e.g. If I put the new minimal kernel build as the first entry, will I get an error message saying that the kernel sizes do not match or that the iso image is too large, or some other strange error message?)
3. Are there any other lilo related problems, options, or tweaks that you think are pretty cool and that I might like to hear about?
4. Would I be better off using GRUB?(I don't like GRUB, but I'm throwing this one in here just for completeness.)
How does the 'testing' version of Debian stabilize? I mean, the updates from upstream are very frequent, so if the Debian maintainers upgrade a package till the very end (for e.g if they just upgrade to 2.6.36), when will they get time to test it (so as to freeze it)?
I would like to remove a specific domU (test01--pv--guest) from my machine. I am not sure how far/to what extent to remove files. Here are the files and properties it seems I should remove:
brw-rw---- 1 root disk 254, 0 Jan 9 01:03 /dev/dm-0 brw-rw---- 1 root disk 254, 1 Jan 9 01:03 /dev/dm-1 brw-rw---- 1 root disk 254, 2 Jan 9 01:03 /dev/dm-2 brw-rw---- 1 root disk 254, 3 Jan 9 11:05 /dev/dm-3 brw-rw---- 1 root disk 254, 4 Jan 9 01:03 /dev/dm-4 brw-rw---- 1 root disk 254, 5 Jan 9 01:03 /dev/dm-5 brw-rw---- 1 root disk 254, 6 Jan 9 01:03 /dev/dm-6 brw-rw---- 1 root disk 254, 7 Jan 9 01:03 /dev/dm-7
Will they be deleted automatically or should/can I remove them? How do I check the need for the other dm-? files? As indicated below, it seems like some may be duplicates.
I also found this set in /etc/lvm/archive/:
-rw------- 1 root root 2909 Oct 17 00:41 Relaise-vg_00000-1453251236.vg -rw------- 1 root root 2929 Oct 24 22:08 Relaise-vg_00001-1530642081.vg -rw------- 1 root root 2924 Oct 25 19:33 Relaise-vg_00002-328450675.vg -rw------- 1 root root 2901 Oct 26 19:53 Relaise-vg_00003-1555350964.vg -rw------- 1 root root 2902 Oct 26 19:53 Relaise-vg_00004-1044927704.vg
[Code] ....
Some of these seem like duplicates. This may be due to multiple attempts to build the volumes. Is there a way to determine if all of the are useful?
I am having trouble getting a Verizon UMW190 configured in Network Manager under 10.04 Lucid as a 'New Mobile Broadband Connection'. As the UMW190 is a 'World' capable mobile Broadband adapter is has both CDMA and GSM capability. I only need CDMA for now. However, when network manager detects the VZ UMW190, it does not offer Verizon as a choice in the Provider list. I searched and found references in this forum for using the UMW190 under 9.10 with gnome-ppp via this link:[URL]and tried it without any luck.I have previously used a VZ UM175 on this machine under 10.04 without any issues as Verizon appeared in the Provider list and the configuration worked without a problem.
If I shutdown from X the system hangs and I have to yank out the power cord. Same on logout.
ctrl+alt+f1 hangs for a few minutes and then starts a terminal; which does not respond to the keyboard.
There are no tty.conf files in /etc/init .
But inittab looks normal to me and includes tty (1-6)
Executing init 6 from a terminal in X will reboot the system
I was thinking this might be a dbus issue, but I am not sure. I also understand some recent issues exist with SysRq sequences. May be a video card issue,,,
Other than normal package upgrades the only changes were a recent change from a VGA to HDMI cable. I can't see why that would matter

I was wondering if a standard Debian 8 system with Gnome desktop does any kind of local dns caching, and if so, what the command is for clearing it. (Assuming I haven't purposely installed any DNS server software.)
I found multiple posts on the Web about unix DNS caching, but with widely different answers across distributions and across time.
I am running Debian on an ARM module (BananaPi).5 minutes ago, i started upgrading the system, but fortunately the power cable moved and the system closed.Now i open it up again and i'm trying to re-upgrade the system but i'm always getting this message
# apt-get upgrade E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
I have installed jessie on a couple of machines. One is configured as the NFS filesystem exporter and NIS server. The other one, I am trying to configure as NFS and NIS client. NFS does not seem too much of a problem, I can mount the exported filesystem to a directory in the client and unmount it, but when I install NIS the system becomes very slow. Any command preceded by "sudo" takes a very long time (a few minutes) to complete. Then, upon rebooting the system, it reports many services failed to start (login, accounts, modem manager, avahi, network manager, exim). When if finally completes, I get a terminal login, instead the graphic login window.
Installed linux-image-2.6.32-bpo on my laptop today and after the reboot i got "no operating system found" . I'm now typing using a Puppy live cddrom .
I have a small LAN. I am in the process of installing a Debian Lenny/Squeeze system into the LAN. I want to send and receive system messages using rwalld and wall.I can send a system message from my Debian system to another box using rwall. I can send a local message within the Debian box using wall in a console.I cannot send a local message using wall Konsole in KDE 3.5.x. The KDE Write daemon fails to provide any pop-up window./usr/bin/wall is installed from the bsdutils package and is set to -rwxr-sr-x.
The ktalkd package is installed. The KDE control center shows a configuration option in Internet & Network settings called Local Network Chat.When not in X, mesg is set to y at the console. After starting KDE and I open Konsole, mesg is always set to n. I don't know how this setting toggles. Further, setting mesg to y in Konsole has no effect on getting wall to work.mesg is set to y when I run xterm in KDE. Then wall works within that terminal window. However, the KDE Write daemon does not see the message in xterm.When I send a message from another system to the Debian system using rwall, xterm receives the message but not Konsole or the KDE Write daemon.
