OpenSUSE :: Continuous Short Term Hanging W/ Multicore + KDE?
Jul 21, 2010
I'm wondering if anyone is having a similar issue to what I'm experiencing. openSuSE 11.2 was very fast on my system. Since installing openSuSE 11.3, I've been experiencing many short term hangs where I'll lose control of the mouse for a few seconds (usually about 2-5) and the system will do nothing. I don't have unusual load during these time periods and I don't really see any spikes during these periods. If I leave a cpu monitor active, I can see a very very light spike one core0 when it happens, but the mouse and keyboard (and seemingly the whole desktop) hang during this spike so I can't see what's causing it, if that's really the culprit.
I am almost suspecting that I'm experiencing an issue with interrupts... since it seems that everything is hanging for a few seconds, then coming back to life. It does seem to happen more often when I'm resizing or minimizing windows... but that's about all I can say as it also seems pretty random.Here's some basic info on my hardware:ASUS M3A78 Pro motherboardAMD Phenom(tm) 9950 Quad-Core ProcessorGeForce GTX 260G15 Keyboard and MX revolution mouse (just in case USB interrupts turn out to be the issue)So, is anyone else experiencing a similar issue? Maybe we can narrow down what we have in common. Oh, I'm running x86_64.

I wanted to add a repository so I took the steps of zypper ar -f ((repo directory)) and got:
Code:
zypper ar -f http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.4
If only one argument is used, it must be a URI pointing to a .repo file.
addrepo (ar) [options] <URI> <alias>
addrepo (ar) [options] <file.repo>
[Code].....

no error in errorlog and sensors are showing fine temperatures . i tried 2 different boards (asus p5qlpro , msi p6mgm fd) with different speed intel dual-core processors

I don't like the 'hide' array on the system tray. I never hide my icons there. There is an icon-by-icon setting to hide/show but this is a little laborious. However, there currently doesn't seem to be an easy way to show all icons, but, at the same, hide pop-up notifications after a short delay. How to implement this?

I recently upgraded my Opensuse dom0 from 11.2 to 11.3, and so Xen from 3.x to 4.01.Ever since, Windows HVM domus hang after a random amount of time. Always within 24 hours of starting though.The VMs are XP and W7, and have tried both hvm drivers and gplpv drivers. There are no errors in xend.log, or the qemu-dm logs or xm dmesg. I have tried apic and acpi both on and off.
If I VNC to them, I can see that they have simply stopped.If I force them off and start them again, there is nothing in the event log of the VM, it just stops and becomes unresponsive, with no associated log entry.I have re-installed one of the VMs from scratch, with a slightly different version of W7. No difference. The stalling even happens during installation, so it doesn't seem like any software I have installed or configuration could be related.

At boot, the system hangs before reaching runlevel 5. No X, no alternative non graphical shells.
Since I have a video card Radeon 9200 I checked the ATI issues. I am running with the radeonhd drivers as suggested. If I boot in failsafe mode, X starts with a really low definition (800x640?), but when booting normally, the system hangs again.
I tried to create a xorg.conf file. Sax hangs the same way as when booting. I created anyway a reasonable xorg.conf using
Code:
Xorg -configure
The first reboot works, from the second on I am stuck again.
I am running suse 11.2 32-bit on a AMD at 64 bit.

I am in serious trouble apparently.
System boots up to loading NVIDIA drivers, it shows mouse pointer then it hangs up!
This happened after brutal force rebooting, because system did not responded properly (especially Nautilus). Probable cause:
forget to unmount.cifs a windows shared folder in the network (mounted with mount.cifs). It happened to me already sometimes (to forget umount.cifs), but never ending with this permaenent hanging up)
-tried automatic system repair with suse boot DVD. It repaired something + changed the bootloader. Problem still there
-rebooted--> system hanging up after NVIDIA drivers. code...

What i meant was, in a multicore system with 'n' number of cpu's, will each cpu have its own linux kernel installed, or will all cpu's have a copy of the same kernel image? Another question regarding multicore is kernel tracing. Since tracing works at the kernel level, then should i perform tracing for each cpu's seperately or kernel tracing can be performed as a whole for all cpu's put-together?

I am experiencing a multicpre problem with fedora14 / kernel 2.6.35.6-45.fc14.x86_64 #1 SMP. (standard from the distro). The host has a total of 2 cores .yet a virtual machine started with 'smp 2' ( or xml : <vcpu>2</vcpu>) will not run on 2 pyhs cores . it will use just 1 core ('top' at the host shows 100%cpu while running an endless loop process on the VM) and libvirt 'virsh vcpuinfo <vm name>' shows only 1 physical cpu used (although 2 vcpus are used : 0, 1) The kernel seems to be an SMP one ( so says the uname -a . what does '#1 SMP' mean ?) . Am I missing something ? same XML on a DEBIAN machine will run the VM with 2 phys cores as should although the host there has 4 cores (>2)Should I recompile the kernel src with some addtional flag ?

We are experiencing a rather odd issue with SSH access to our opensuse linux server. When accessing it via SSH on the local network everything works fine and there are no issues. However, when accessing it via SSH from an external location it hangs randomly. We can log in without issue and some commands seem to work ok. If we attempt to run a command such as "top" the SSH session simply hangs permanently. using "strace" the process hangs at different points so it is not a particular part of it's execution that appears to be the problem.

I have installed many Linux distributions, but I have never tried openSUSE! So I thought it must be time to try it. I pop the dvd in(I checked the md5 of the iso and checked on the bootable disk) and when I go to install it pauses on the "Probe hard disks"Things I have done:
- Re-checking the integrity of the disk and iso.
- Tried booting with the safe kernel.
- Tried leaving it for ages

I have been trying and failing to install openSUSE 11.3 for the last couple of days to replace my Ubuntu install.
I have downloaded the openSUSE-11.3-GNOME-LiveCD-i686.iso (have downloaded numerous times in case it was a problem with the mirror I used) and done the standard dd stuff, as well as trying it from my windows partition with the ImageWriter app.
When I try and boot with the USB drive plugged in my system hangs at the boot screen and the usb drive starts flashing as if it is being read, this continues indefinitely and never goes beyond the boot screen and i eventually take the usb drive out and restart.
When plugging the drive in when Im in ubuntu it shows up as "openSUSE Live CD GNOME" and all the files seem to be there. In gparted it doesn't recognise the partitions or anything but I presume this is normal... Also reduces the size of my drive to the size of the Live CD but again I presume this is normal...
I have also tried installing using the NET iso however I have exactly the same outcome.
This laptop is a Acer Travelmate 8371 and has had Ubuntu, Mint, and Windows 7 all installed from the same USB drive. There is not optical drive so I have no other ways to install openSUSE.

I am running 11.3 for about 4 months and it suddenly started to hang intermittently, sometimes many times a day. Once KDE restarted and other times the screen went black. Most of the time it was just hanging and I needed to force a shutdown. The only clue I got is KDE displayed a notification saying "Disabling IRQ #24" not long after it started to go nuts.
After searching around, I figured the problem was with my external video card so I pulled it out 2 days ago and so far it didn't freeze again. After searching around some more, I found many users fixed very similar issues by upgrading to kernel 2.6.35 and I am ready to go for this solution. But now, I couldn't find out how to upgrade the kernel. People said it can be done in Yast but I only see version 2.6.34. What is the easiest way to upgrade?

I wish to know that which gcc release version had support on ARM 9 multicore system by using pthread library for its parallelizing method on ecos rtos.I assume that the compiler that support the single ARM 9 processor will surely compile its multicore version also.But i need a clarification about it.It is good if you give a article or provide a suitable link on the ARM multicore programming and its compilation method

I've got an intel i7 920 CPU. It has 4 cores, but thanks to hyper threading technology each core could run 2 threads so in /proc/cpuinfo it shows "8 processors".
1. what would be the optimal -j flag when compiling programs on my CPU. I've come across -j7. Why 7?
2. Where and what would I put this flag to make it permanent (eg. .bashrc?)?

i have hd encryption activated on my swap and home disks. now every 20 min or so (not really periodic but definetly reproduceable) my system hangs completely for about 4 - 10 sec while the hd led is on. i have a dual core cpu which makes this even more odd. could this be a side effect of hd encryption especially on the swap partition?

I have recently loaded the new LTS SERVER 10.04 release and it loaded without errors. My only issue is that it does not seem to correctly identify the Dual Cores for each processor. (The HP xw9300 I have has two hardware CPUs - each one being Dual-Core - so there should be a total of 4 CPUs recognized - unless I am mistaken?) How I can debug the processor recognition for multi-core support to get the additional cores recognized.
My /proc/cpuinfo file looks like this:
Code:
xxxx@hostname:~$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 37
model name : AMD Opteron(tm) Processor 248
stepping : 1
cpu MHz : 2194.452
cache size : 1024 KB .....
address sizes : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp

I have some trouble booting the current KDE Live Cd (11.2) on my Laptop. I tried USB and CD both. The laptop hangs on the bios bootscreen and I cant select any further option like a boot device. No problem I have with an Ubuntu CD.

New Intel x64 system installed with Opensuse 11.1 (like the KDE 3.5 option) and has been running well until today. Booting stops at "starting jexec services". Even while booting under "failsafe" system halts at "starting jexec services". Unable to boot to command prompt to attempt repair. Ran "repair" option from install disc with no good results. Still will not boot past jexec services.

Every time I boot up OpenSUSE 11.3 it hangs at the same "position" for approximately 3 minutes and then continues to boot. Unfortunately I see no corresponding error log e.g. in dmesg output. Hence, I don't know what is the reason for that. Here is my dmesg output. The delay occurs at 20 seconds after beginning of boot process (line 1085). I also analyzed the boot process with bootchart.
My computer: Notebook Lenovo ThinkPad R400.

By trying to install opensuse 11.4 / 1 the installation hungsup at a late level. After rebooting the system, the configuration goes on. When finishing the installation on that way, there are no menus so you can to simply nothing. The problem of system hanging exists also with version 11.3 final release but after rebooting the configuration goes on and when finished, you have the menus.

I had some issues with my system hanging on the automatic configuration of the install so I searched the web for the issue. After reading this thread: Hangs at end of SuSe 11 install I used acpi=off apm=off nolapci as the install options and it worked. My question is, do I need to add those options to the /grub/menu.lst or will the install do that?

I just installed OpenSUSE 11.4 on a completely blank machine, empty disks, etc. using a Network Install. The install appeared to run OK, but when it rebooted to do the configuration, it hung. I tried a manual reboot a couple of times, then booted in FailSafe mode - came up OK and ran through the auto-config. Now, it still boots up ok in FailSafe, but in normal mode I get the wallpaper on the screen, but it hangs there.

The freeze's on my machine only appears when i monitor the temperature of
the gpu. Normally i use gkrellm to monitor temperatures including the gpu temperature. When i stop gkrellm there a no more freeze's on my system. Then i started nvdock which also monitor the gpu temperature and the freeze's are back. Stopping nvdock make the system working normally. I have done a few reboots now, warm and also cold starts und everything works normal.

My desktop becomes very quiet once windows7 is loaded.. but the fan, maybe cpu fan runs continuously in fedora 13. though it's not quite noisy, I thought I didn't install the correct drivers for the Asus h55 mb. the mb cd has a directory "isolinux", which contains a boot.cat, isolinux.bin, isolinux.cfg along with two subdirectories, data & src. but isolinux.bin is not executable.. how can I install the drivers in fedora?
