Debian :: Kworker Hogging CPU On New Jessie Install - EDID Checksum Is Invalid
May 16, 2015
I just installed jessie on a machine that had been running wheezy with no problems. Now I see that a kworker process is hogging nearly 100% of one of the CPUs. I am not sure how to proceed with solving the problem even after doing a number of Google searches.
I'm not sure if this is related, but I am getting the following when I run 'dmesg':
My hardware is:
cpu:

Here is the "top" display, showing 75.2% of the CPU on kworker/1:2 and 27.6% of the CPU on kworker/1.1:

I burned a new disk with ubuntu 11.04 image and I managed to boot the live cd using my external monitor, I've installed and went into my monitor settings, it displays my external monitor as unknown and doesn't even detect my laptop screen. Changing the driver being used in my xorg.conf to vesa allows me to boot properly and ubuntu uses my laptop screen (yet it still detects it as an unknown monitor). Installing any nvidia driver and using it breaks my system. Heres an image of the laptop when using the nvidia driver (btw I can still hear the ubuntu sound that plays when its reached the logon prompt).
I have got a very frustrating problem. I am not new to Ubuntu but this time I bit my tongue! Actually it is a problem related to my graphics card "Intel 945GM" , it is a real crap card but it is working fine with Windows XP pro (I use windows just for testing)!
Problem : My monitor DELL ST2310 would not work under DVI mode (only VGA mode is working fine)! I tested with Kubuntu, Ubuntu (several distos), Fedora 13.. Upon booting, I get this error message :
Code: EDID checksum is invalid remainder 130 the monitor DVI connection is working perfectly under Windows XP. This means the Intel 945GM cannot read the EDID hexadecimal data transmitted by the monitor through the DVI connection. Yet, System recognizes the graphic card's DVI-D port but set it as disconnected.
I have installed a fresh copy of FC14 and when I logged in locally for the first time I was getting the error messages below. Now these same messages are filling up my messages log and it's running non stop in the background. Has anyone seen anything on this error? I have searched through Google looking for help and I'm not finding much.
This box is a simple file/web server with no monitor hooked up and no GUI. I have also included the lspci ouput below if that might help. Really looking for any suggestions or input on how I might stop the error reporting since is filling up my log files quickly.
I'm running 2.6.32-28-generic. I have a raid1 (two 1tb drives with two partitions... one for / and one for /home.) After a power outage, I'm seeing grub complaining about /dev/md0 not existing (ALERT! /dev/md0 does not exist. Dropping to a shell!)
I booted to the latest live CD to have a look around. My dmesg output includes these ominous lines:
I am trying to install Unbuntu 11.04 on a Via raid 0. I have windows already setup and it boots fine, but Ubuntu does not see the raid set. Running dmraid -ay (or any valid switch with dmraid) returns :
sudo dmraid -ay -v ERROR: via: invalid checksum on /dev/sdb ERROR: via: invalid checksum on /dev/sda no raid disks
mainboard is Asus M2V, with 2x Hitachi 250Gb disks in raid 0 configuration set in BIOS. I have a 3rd hard disk on the onboard Marvell 88SE6121 sata controller but this is not seen at all by Ubuntu either. I was thinking of installing it here if Ubuntu does not work the RAID, but no go it would seem. I do remember installing an earlier version of ubuntu on this very same board using RAID 0 (2x 80Gb drives at that time) and the RAID was reconised and worked fine straight from live cd to full install.
I'm not sure what has happened. The last update I did was on the 15th. I've rebooted a number of times since then and haven't updated/installed any packages. But clearly I must have changed something but for the life of me I can't remember changing any settings video related. Now X does not start. This is what I get now
I am running Wheezy 7.9, I have a Biostar motherboard with integrated Intel graphics (945 chip set), and a Viewsonic va912b 19" LCD monitor. I have recently been having problems with the computer not being able to read the EDID data from my monitor. About half the time the EDID is read okay. So, in order to set the monitor to the desired resolution I have created a shell script to set the resolution after I log in. Knowing that my monitor supports 1152x864 @75hz I used cvt to get the modeline info.
Code: Select all#! /bin/sh #! /etc/init.d/monitor_1152x864x75 # #add monitor resolution not being found at startup #data from cvt xrandr --newmode 1152x864_75.00 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync xrandr --addmode VGA1 1152x864_75.00 exit 0
It works fine, but I see a difference between what cvt gives versus what I see in the xorg log file (when I get a good EDID read). Here is what I see in the xorg log.
Notice that there are some small differences in the horizontal and vertical timings, cvt versus xorg log.
The biggest difference, to me, is that cvt has -hsync and the xorg log shows +hsync. I would assume that the data shown in the xorg log file is based on what was received from the EDID and therefore is what the monitor expects. Is that a correct assumption? And might using -hsync as per the cvt, versus +hsync, affect the monitor operation? Using -hsync does not appear to create any kind of video artifacts (tearing or distortions).
I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?
I had problems with the system not reading the monitor EDID and have fixed the problem by adding an override file in xorg.conf.d and all of that seems to be working well (although the system has not failed to read the EDID since I implemented the override. go figure).
The thing that I am wondering about is something I see in the Xorg log file. At the end of the log file, after everything seems to be configured, there are six (6) identical blocks of information regarding the EDID and modeline settings. Is this normal or is X stuck in some kind of loop? Everything is working and I am not waiting an inordinate amount of time to log on, or after. Just curious. Here is the log file.

I recently upgraded from wheezy to jessie and everything went as planned with dist-upgrade. However I just noticed that I can't play any video file. I thought about upgrading vlc, as it was already installed but it had dependency problems. So I tried to remove it
Code: Select allsudo apt-get remove --purge vlc
Then If I try to install vlc I receive this message:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may resolve the situation:
The following packages have unmet dependencies:

Now, I thought about removing vlc-data but I received this message saying that 253 packages will be removed (624Mb worth of applications). Am I uninstalling my entire system with this?

Now from windows using Remote Desktop connection, an attempt was made to connect remotely, I can see xrdp working just fine, but when I am logging into xrdp-sesmanx11 with the username and password, it exits out suddenly, are there other packages that need to be installed?
I am new using linux and don't have too much experience in terminal, however I am curious and work hard. I have an imac G5 powerpc with 2g processor, 768 mb ram and 232.7g hard disk. I recentrly installed debian 8.0.0 (jessie) with xfce environement. I have three other computers (two with xununtu runing and one with windows) using dropbox to sync all my work in differents places, so I use dropbox to get all synchronized. I don't want to change all the pc's to other cloud service, I would like to install dropbox in this machine.
I installed libnet-dropbox-api-perl, pear-channels and pho-dropbox packages from the synptic package manager with the hope to use dropbox...but I dind't even find something colled dropbox in the pc.
My question is: is it possible to install and use dropbox in this powerpc machine ? if yes, is there a tuto (for dumps) to get it ?
I am a experienced Windows person and my roots go back to DOS and the first version of windows. I am pretty good with computers but have little to no experience with Linux or Unix. About 30years ago I managed to make a painful transition from DOS and xTree Gold to Windows 3.1. Now I am leaving Windows behind forever...
I have installed Debian Jessie from a DVD that was made with the debian-8.1.0-i386-DVD-1.iso.
I have it installed and running with the Gnome desktop and now want to use the KDE desktop. As I understand it I have the files for the KDE desktop in my install and I see some KDE files the in the Packages app. But I don't know what I have, where it is, or how to use it.
I just cannot figure oout how to get the KDE desktop installed and running. If it is practical I would like to keep Gnome for now, switch to KDE as the defaultdesktop.
I have spend some hours googling and searching this forum and cannot seem to find anyting on switching or changing desktops from and with the Jessie install.
And if it can be done from Gnome that would be easiest for me because I am not much of a command line person yet and don't have a manual for doing that yet. But can use a terminal and enter commands if they are stated.
I'm trying to install KDEConnect on my 64 bit Debian system. It's failing because of dependencies.
Tried installing the first dependency, sshfs. It said it cannot find the 64 bit package. So, I tried the 32 bit. That one depends on fuse. Tried to install fuse 32 bit. hat depends on sed. Tried installing 32 bit sed, but the package manager said it's risky to replace 64 bit sed with the 32 bit variant.
I stopped here thinking that I'm risking some stability and the road to the finish line is not visible till the end, meaning I might lose hours trying to do something that fails at the last step. This happened to me few times in the past (with other software) and I really don't want to repeat the incident. I need a stable system and I need my time.
The question is: how to get installed kdeconnect package on Jessie 64 bit ...
I'd like to have acestreamplaer installed in jessie, but I am not able to do it....
I tried with Acestream repos: deb http://repo.acestream.org/ubuntu/ saucy main

I installed Jessie day before yesterday on a freshly formatted partition. After a random time, it hangs. If I am playing music at the time, the music continues for a few more seconds _after_ the mouse and keyboard become unresponsive, if that is useful.
Sine I did not understand how to pick the desktop during the installation, I installed Gnome. Afterwards, I installed KDE. Now I have a lot of Gnome stuff around I don't really need. But they are in principle compatible, right?
This morning, the hang was almost immediate after logging on. Only Iceweasl and Amarok and a Konsole were running. I attempted to start Icedove, when everything hung.
Here is the relevant part of the syslog.

I have been building a debian jessie system reasonably successfully but have come unstuck with libpam-mount. On a previous Ubuntu saucy system I simply installed it, created the appropriate pam_mount.conf.xml file and mounts would happen when users logged on and dismount on logoff. With jessie I can see that there is a libpam-mount package in main but when I try apt-get install it fails. If this package has been obsoleted (as one of the messages indicates might be the issue) what is the jessie way of handling this?

I installed Jessie with the RC1. URL...A2) The network install images for testing (jessie) can be found at URL...However, unless you want to test the installer for testing the better choice is to use the stable installer to install a minimal stable system and then upgrade to testing by changing your /etc/apt/sources.list file.
Somehow got it partly to work. I have a new installation and I am using the 4.1 kernel now. I can switch on the Radeon chip which is great, but still have some trouble when trying to turn it completely off.
I have an Acer Aspire 4820TG Laptop with: Core: i7-640M integrated graphics: Intel discrete graphics: Radeon Mobility 5650HD
I have installed Debian Jessie. After installing the non-free firmware for my ATI chip (following [URL] .....) so I could use vgaswitcheroo, the system broke.
The problem looks as follows: When I start the system the graphical login screen gets stuck and the console tells me first:
Code: Select allradeon 0000:01:00.0: Userspace still has active objects!
then a lot of numbers, then
Code: Select allradeon 0000:01:00.0: ring 5 stalled for more than 10000 msec [drm:uvd_v1_0_ib_test] *ERROR* radeon: fence wait failed (-35). [drm:radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on ring 5 (-35).
and this repeats once (or twice?) until several new messages arrive.
Those pause at
Code: Select allFixing recursive faul but reboot is needed !
Then again lots of more error messages until the everything freezes, with the last message
Code: Select all---[ end trace 13dfd971ff8e0aed]---
(Might contain typos. I don't know how to get the whole messages since the system dies a minute after booting and I only have a few seconds after the error messages start)
Even when I prevented the xserver from starting at boot I still got the same problems.
I would very much like to be able to switch between my chips, because I can only use external monitors when the ATI chip is active, but I would also like to be able to use the battery saving internal chip option.
I also tried to install the proprietary driver (though I would prefer if I didn't have to do that), but I couldn't get the xserver to work while it was installed.
Musescore 2.0 is available but only for Sid, I have just installed Jessie since I wanted the stable version. I was wondering if it was possible to install that packaged only from the sid distribution on jessie. How should I proceed?
I have noticed that when installing Jessie, the graphical installer downloads updates to packages while installing if connected via Ethernet to the Internet. Remaining disconnected solves this problem. Is there any way to avoid this and install without downloading files other than apt lists?
Lately I have noticed when I am trying to install something I have been getting 'Hash Sum mismatch'

I have been using linux for about a year and have run into a new problem I am unable to solve. It started when I attempted to install some packages I needed to get VirtualBox to run VMs. I am on Jessie.
I am unable to install various packages, including gedit, aptitude etc. I do not think it is a problem with my sources.list as my laptop has the same sources.list and I am not encountering the same problems on it. Packages will not install any dependencies. -f install isn't doing anything for me.

I tried to check for held packages with

I have a fresh install of Jessie, and am having issues with debconf.
I have been trying to change to mdm from the default lightdm display manager. I have downloaded and installed mdm (apt-get install mdm) but when I run dpkg-reconfigure mdm nothing happens. As I understand it, I should get a menu that lets me choose which display manager to use.
I also installed lirc so I could get my IR remote working again, but when I run dpkg-reconfigure lirc nothing happens. I am supposed to get a menu with various options to choose from.
I have tried dpkg-reconfigure debconf and this gives me the menu with different options to choose, like it should when trying dpkg-reconfigure lirc or dpkg-reconfigure mdm. I tried using dpkg-reconfigure debconf to choose different settings, such as gnome, or editor, but they don't work either.
I recently have started playing with various distros (Mostly just Zorin and Debian) and have been trying to find a GUI I can actually comfortably use without wanting to punch my screen. This lead me to cinnamon which looks like something I could actually use.
I performed a fresh installation of Debian Jessie without the desktop environment and print server (System Utilities or whatever that option is called was left checked) and after the system installed and booted I proceeded to login as the root and install cinnamon. Unfortunately afterwards my system would be nothing but a black screen with a box saying that cinnamon had crashed and was running in fallback mode.
However if I let a fresh installation install the default GUI of xfce and then perform the cinnamon installation, cinnamon will install and run. My question is why doesn't a clean install with cinnamon work but installing cinnamon after another gui does? I don't get any apparent error messages beyond cinnamon crashing and I'm still fairly new to Linux.
I have a Dell laptop (inspiron 1150) which was dual booting Windows XP and Ubuntu 9.04. I have successfully installed Debian Jessie Standard over the Ubuntu. I pre-partitioned using gparted-live to make a separate single partition for the Debian install. Guided partitioning was then carried out by the installer producing separate /, /home, and swap partitions. After installation, the grub menu shows an entry for Debian and Windows XP. I can boot Debian, but not Windows XP. The symptoms are the same as reported in other forums: A terminal is displayed, vanishes and the system reboots defaulting to the Debian boot.
The grub.cfg file for the Jessie system has an other-os entry:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" { set root=(hostdisk//dev/sda, msdos2) search --no-floppy --fs-uuid --set=root cc0ce0ab0ce091ae drivemap -s (hd0) ${root} chainloader +1 }
The original Windows entry for the Ubuntu install was:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" { insmod ntfs set root=(hd0,2) search --no-floppy --fs-uuid --set cc0ce0ab0ce091ae drivemap -s (hd0) ${root} chainloader +1 }
The partitions produced by partman look OK (during the pre-partitioning I did not touch sda1, sda2, or sda3):
Code: Select all~ # os-prober /dev/sda2:Microsoft Windows XP Home Edition:Windows:chain
So it seems that everything is in place, but there are perhaps important differences in the grub.cfg files. Are the two "set root" commands equivalent for example?
I am having a problem with my new Toshiba Satellite Laptop... I had installed debian for some time but last week suddenly stopped working.
- the computer stopped working at all... nor bios access. - I did a new bootable installation in USB drive and downloaded the latest debian iso from official website and created the bootable device via dd as usual. - I installed the new debian but after I removed the usb drive in order to boot into my new system. I was taken to a screen saying "Start PXE over IPv6 -- Start PXE over IPv4 ..." I followed several links looking for a fix, and all of them lead me to disable network boot option in BIOS setup... - I disabled but after that it appears a new message "No Bootable device -- Press restart system" and nothing happens from there. - I have found info in Internet regarding this issue, but all I find is "windows related" - Someone recommended me this: "The BIOS can no longer recognize the hard drive as a bootable device. This could be for a number of reasons. Your best bet, if it is still under warranty, is going to be to bring it back to where you purchased it" - But instead, what I did was to create a new bootable device, this time containing XUBUNTU and installed it to the machine, I had the good news that the installation proceed without any problem, so I could figured out that my machine it is still alive... - Back to my issue and hoping that something unexpected happened that fixed the machine, I got back and did a new Debian bootable device, also hoping that the latest was corrupted or something, but after reboot to my new system... the problem persisted again. - I chose to have 1 partition in full disk.
Now I don't know what else to do... I don't like ubuntu, I have used debian for some years and I want to keep using it and I would not like to be forced to move to ubuntu or xubuntu for this.
