Ubuntu :: What Is Kslowd001 Process / Why Cannot Be Killed
Oct 19, 2010
In Ubuntu 10.10 on a REALLY old laptop, everything works fine - except the system occasionally gets a lag spike, where the CPU is suddenly being throttled. This wouldn't be a problem, except my mother's using the laptop to play backing music for her choir and the CPU spikes are causing the music to stutter. After much searching and eventually resorting to TOP, I found that the CPU was being throttled every 10-20 seconds or so by a process called, "kslowd001". "sudo kill -9 `pidof kslowd001`" did nothing, nor did, "sudo killall -9 kslowd001". It doesn't want to die, it just wants to throttle the CPU, and I just want it to stop. What does this process actually do? Why can't I kill it? How do I switch it off, or otherwise stop it from throttling the CPU every couple of seconds so that we can actually listen to music or watch videos from the laptop?

process kslowd00/kslowd001 it eats 60% of my cpu and 15% of my memory ... i can't kill it even as root.this process makes my computer slower than" IBM 704 running fortran programs "... I've faced this process using Fedora 14 and now with Scientific Linux 6(RHEL 6 recompiled) SL 5.5 didn't have this.

I've always wondered whether my process kills when I am in the process of doing something during my ssh session. For instance, I ssh from my local box to dev-formbox and did an scp transfer to another remote host. All of the sudden, I lost ssh connectivity on my local box due to network issue. Will the scp process (or any of my process that I am currently doing) kill also once I loose the ssh session?

recently a weird error occured on my Ubuntu Karmic. When I shutdown (or reboot) the os, the flashing logo shows and then the whole process hangs with last few lines of shutdown log displayed. The last line then says this error:
Code:
init: rc main process (pid) killed by TERM signal where pid is actual pid of that process.
Then I have to shutdown the computer manually with hardware button. It's no big deal, it's just not that comfortable and I'd really like to know why this is happening.

I am reasonable linux skilled. I am running a VPS account with Debian Linux Lenny, Virtualmin/Webmin. This has only recently started but I don't know at what point, as haven't done much on it recently but applied some updates. There's always at least 50% free ram when it happens (of 512mb) and basically no CPU activity. I've even tried killing off all process's apart from what I believed to be needed to test, (init, sshd, loggers). I can find mention of the action anywhere in any logs, even though I have klogd and syslog running. It seems to happen at varying intervals fairly regularly with certain processes. I've had it happen with a big 'rm -r' but more regularly with make's , make install's, apt-get (while its awaiting your reply to proceed), and rtorrent.
All I get is "Killed" and back to prompt,
If I type "echo $?" I get '137'

I just installed Ubuntu on a Cr-48 netbook, which has an odd custom bios which can't boot regular bootloaders/kernelsI'm therefore using the existing kernel on the machine rather than the Ubuntu one, with no initrd/initramfs, just booting directly to the Ubuntu root filesystem.t's just a minimal text mode install right now, from the alternate installerAt boot time, plymouth crashes. It doesn't seem to actually affect the system, everything still boots just fine, but it doesn't seem like it should be doing that I get:
Code:
mountall: Disconnected from Plymouth
init: plymouth main process (70) killed by SEGV signal

I upgraded from Ubuntu 10.0.4 to 11.0.4 on a Dell Optiplex. Now, when I boot, I am given the option to boot into different kernels. I select "ubuntu, with Linux 2.6.38-8-generic", which results in a black screen that reads
Code:
init: plymouth main process (58) killed by SEGV signal and that's where it hangs. Pressing ENTER or hitting Esc does nothing. What steps can I take to recover my machine and all the files I used to have on it?

I was transferring data from one computer to my laptop and crash error came up on my laptop...
Error 1:
Nautilus-2.32.0-1.fc14 Reason: Process/usr/bin/nautilus was killed by signal 11 (SIGSEGV)
Error 2:
Openoffice.Org-Brand Crash
Reason: Process/usr/lib/openoffice.org3/program/soffice.bin was killed by signal (SIGABRT)
What could be the problem? Is it serious issue? I have been having security issues with Windows and are those issues begun once again? I have been under targeted attack since 2005.

I wanted to change the look of my login screen, so I installed gdm-2.20 thru the terminal (apt-get install) and then it asked me what I wanted the default set as and gave me 2 choices:
gdm
gdm-2.20
I picked the latter. Then I restarted the compy and... text. It keeps telling me that the X server is... not configured correctly and that I need to restart GDM when it is. So, I need to know if there is any way of rewriting the xorg.conf to work with my poc (piece of crap) video card. I have a backup of the default xorg.conf for use with NO video card... but then I wouldn't be able to use my video card...

I've been a Windows users since waaaay back when (ahh...Windows for Workgroups 3.1). I've tried Linux in the past (Mandrake many years ago), but didn't feel it was quite ready to be a Windows substitute for me.A couple of weeks ago, I downloaded the latest version of Ubuntu (10.04) and installed it in a dual boot setup with Windows XPSP3. All seemed to be running well, until it came time to install updates in the Update Manager. First an update for GRUB, which promptly killed GRUB and left me with "Minimal BASH-like line editing is supported" message and a GRUB prompt. After booting up the Windows XP install CD, I was able to rewrite the MBR and get back into Windows.
I deleted the Ubuntu installation and reinstalled it, making sure I didn't allow it to update GRUB after finishing up. The other updates listed installed fine and I was able to dual boot with ease.Another round of updates were listed yesterday when I booted up in Ubuntu, I made sure not to include the GRUB update, downloaded and installed them, rebooted and was faced with "Minimal BASH-like line editing is supported" again. Argh. Once again I had to pull out the Windows CD and run FIXMBR to resolve the boot problem.I'll admit to being tempted to just go back to Windows completely (while not perfect, atleast I can get it to boot after updates 99.9% of the time) and forget the idea of running Linux if I'm going to be faced with having to reinstall the OS everytime because something killed the boot loader.

I am was running Natty 64 bit on my computer when I though I would download kubuntu desktop so I would have it as an option when logging in. I restarted, played around with KDE then restarted again, choosing "ubuntu" as the desktop manager. Then unbuntu told me I did not have the graphics power (or something like that) to run unity and booted me into gnome 2.xx. Now I cannot boot into unity. Every time I restart it boots me into gnome. How can I fix this?

I have an HP mini 110. In order to get my wireless working I had to use a fix with broadcom, sadly I don't know exactly what I did to finally get it working. My problem is that in fixing my wireless, my mic died. I'm not the most advanced with Linux so I have no idea as to why this may have happened. I have seen that this is a reoccurring problem that continues to not be addressed.

I have an ancient laptop, an IBM T-20 with a Pentium 3 and 250 megs of RAM, which works great for blogging and email. I have used Ubuntu on it for nearly four years now. Last night I upgraded from 8.10 to 9.04 and now it won't get to the log-in screen. The BIOS splash screen appears, then the GRUB screen, then the Ubuntu trademark screen appears, with the horizontal progress indicator scrolling from left to right. And when it gets all the way to the right, the screen goes blank. Then the screen flashes twice, as if it's trying to display in a resolution it doesn't support, and then it goes blank again. The HD activity light flashes about every five seconds and the keyboard is unresponsive.

I've just resolved a Grub problem after reinstalling XP.
See this thread: [url]
I've installed Jaunty and then Karmic in recent weeks (clean installs) after having a Jaunty WUBI install.
After the Jaunty install the sound in XP started behaving poorly,but came right after some reboots.
After the Karmic install I got no sound in XP.So I reinstalled XP and sound was ok,but I had a Grub problem and reinstalled Grub2.
This killed the sound in the newly installed XP.
I know this doesn't make much sense -Installing Grub shouldn't have anything to do with XP's sound.
The motherboard is a ASUS P5K SE with Realtek ALC883 Audio built in,but I'm using a Creative CA0106 Audigy as the sound card.
I've checked that the selected sound card in XP is still the Audigy and I've checked the driver.
This is the output of aplay -l in Ubuntu:
Code:
It isn't a big deal though.99% of my usage is in Ubuntu.I only use XP for a couple of apps.

Long story short my roommate has been using KDE 4.4.2 for a few weeks and enjoying it, so I figured I would give it a shot when I saw this on the Kubuntu front page. I added ppa:kubuntu-ppa/backports to my software sources and asked kpackage kit to look for updates, it found a bunch, plus around 25 blocked updates. I figured they were blocked because they depended on some other update I was about to install. I told it to start updates and left it on its own for a while. About halfway through KDE crash handler popped up saying the network manager crashed, so I told it to restart, plugged into my wired connection, and continued updates. Once it finished, their were still 25 blocked updates to I figured a restart was in order. Once I restart I get to the log in screen, log in, and then I am prompted with this message by the KDE Crash Handler:

A quick note for other frustrated Ubuntu users out there. I have a D-Link DWA-510 PCI wireless card (RT61) that just stopped working. After wasting hours searching posts and asking for help, I've determined that there's a problem in the latest Kernel to be rolled out.
I have now installed StartUp-Manager, and used it to boot into the old 2.6.31-22 kernel still on the machine and, hey presto, wireless is working again. It seems like the simplest fix by far.

A kernel update just killed my ATI graphics driver.
Trying to install proprietary graphics driver fails and points at /var/log/jockey.log
This ends with

If I can't sort this out I'll have to try rebooting into the old kernel to get the graphics driver back. The dreadfully slow scrolling in the browser is starting.

I created a 2nd login that I set up with Gnome instead of Unity. Unity has a few things that drive me nuts like no notification area among other things. I want to still be able to access Unity to try to get used to it, but will probably use gnome mainly.Anyway, I like using the compiz desktop cube effect (also something I could not do in Unity). When I activated it, all my title bars (the top bar in most all windows) vanished. I have seen this before, but the normal fixes aren't working.
This is one thing that still bugs me about Linux/Ubuntu. A couple clicks and you just hose your desktop/ computer. It is not that easy to screw up a windows machine. It isn't even as if I clicked on something wrong.Is there a something about 11.04 that causes a bigger problem with compiz?

Machine specifics: Win Vista with Ubuntu 10.04 installed via Wubi. Upgraded from 10.04 to 10.10 - killed Grub. Following other posts, I booted off a 10.04 Live CD and ran boot_info_script. The results are below. It's telling me core.img cannot be found - can someone please tell me what to do next (before I blunder on and make things worse!)

Fooling around with trying to edit splash themes, and in trying to apply one, I broke the startup splash. The shutdown splash still works. I know that update-initramfs -u is supposed to fix this, but it hasn't. I run dpkg-reconfigure plymouth, and it gives me the list of themes; I can pick one, and it seems to do its thing; I run update-initramfs -u, and that looks like it worked too; but then I reboot, and the shutdown splash is unchanged, and the startup splash is just a black screen until GDM loads. It's as if I hadn't changed anything.

i tried to get some glx support to my X11/xfce4 so i read some threads and i just wanted to try out nvidia-settings to check out how far i've come. it told me to run nvidia-xconfig (which i did) afterwards X refused to start at all, so i copied back the old xorg.conf.i know that X has changed a year ago or so and xorg.conf isnt really of any use (so that file is "like" empty, just three lines or so).whatever, now i cannot login to my old xfce4 environment, i get the loginbox and type in password, after 2 secs i get a black screen with some errors (blinks away after half a sec) a black screen with a cursor and then get back to the login screen.

I have a Dell Inspiron 700m. I've been running Ubuntu since 2008. Every time I re-install the O.S. I have to alter the video driver. When 10.04 was released it crashed the system and I couldn't figure out how to fix it so I left Karmic on and all was well. Well the DVD/CD drive never worked right under Karmic but no big deal.
Anyway, last week I attempted an upgrade. Everything went fine until upgrade finished and it was time to reboot.
Reboot hung, so I ended up killing the power and doing a cold boot.
Now when booting from the hard drive, I get a brief flash of the Ubuntu welcome screen (in the wrong resolution) and then things die. I'm left looking at a grey curser in the upper left.
Worse yet, I can't boot from a live CD or USB. Neither, Ubuntu, openSUSE or Puppy Linux will boot from CD or from USB.
I double checked my boot order in the BIOS and still nothing boots. I reset the BIOS to factory Default, still nothing boots. I disabled the hard-drive in the boot up order in the bios and still nothing boots.
I can't figure out what happened and I can't access the machine at all exepet to enter the BIOS.

I'm running a dual-boot machine with Win7 Ultimate 64bit and Ubuntu 11.04 64bit, both kept up-to-date. Now the weird problem is that I don't get any sound at all except in Ubuntu. Everything works fine here, but Win7 is silent since a couple of days. At first I thought it was a Win7 problem, but it isn't. And I don't have a dedicated sound card but am using onboard/internal sound.
In the meantime I've installed several others Linux distros (the latest versions of Zenwalk, Vector Linux, and anti-X to be precise) instead of Ubuntu, and I didn't get any sound at all in any of them. So I've now re-installed Ubuntu 11.04 from scratch and have I sound again, yet still only in Ubuntu and not Win7. And I've also installed Win7 from scratch, just to be sure.
For those who are familiar with Windows, the "green volume bars" are nicely moving up and down (yeah, very technical phrasing) when I'm playing videos or music as they are supposed to - there's just no sound to hear. The reason why I think that this problem is related to / caused by Ubuntu is that everything worked fine until the last Ubuntu update a couple of days ago. And if it was a Windows problem, at least the other Linux distros ought to produce sound.

I want to use myscript.sh to auto-start an application. I put myscript.sh into /etc/init.d/ and run "update-rc.d myscript.sh defaults". After reboot, I can see my application was started (its log file was updated), but I cannot see my application running if I do ps -ef. I suspect it is killed by the OS.
