Hardware :: SD Card - Debian Sid - Mmcblk Device Dies Under A Heavy Load
Feb 24, 2010
Is there a way to switch a internal card slot from /dev/mmcblk0** to /dev/sd** ? I'm backing up (via rsync) an ebook directory (1.9gb) to sd card and get massive i/o errors, card turning read-only,etc. This is via a built-in slot on a toshiba laptop. When I use a card reader, the card attaches to /dev/sdd1 and all is fine.
This is a new Sid install. The laptop's card slot worked fine under Ubuntu 9.04 and still works if the amounts of data are small. All I can figure is that the mmcblk device dies under a heavy load...
i run right now digikam and rebuild my thumbnails. It seems like that this task takes a lot of cpu power and its not digikam itself, rather xorg takes the load. Is this right? I just wonder.
I installed openbox and pcman on my old desktop and was able take the desktop ram load from 275mb to 120mb. (openbox, pcman, kupfer, gnome-panel) I was so pleased with the increased headroom and performance that I wanted to do it on my macbook. Usually my macbook has as desktop ram load of about 350mb... which I find excessive as that is heavier than OS X. That's running gnome, nautilus, compiz, and gnome-do at startup.
I performed a similar procedure today to create the same setup on my laptop and... strangely, my ram usage on the desktop is still close to 300mb! I've brought up system monitor and added up the ram of all the processes it detected myself and it only added up to about 50mb. How is it that my desktop is still so heavy in a minimal environment?? (both machines are Karmic 9.10, by the way. The desktop is hardwired to the internet while my laptop uses Wicd)
I just want to tell laptop users how they can protect their hdd from heavy load cycle count (spin up/down of the hdd) when using battery.If you are not sure then just type this command several times in interval of 1-2 minutes, and you will see how much the hdd head spins down, and up: Code: sudo smartctl --all /dev/sda | grep -i load_cycle.Change /dev/sda with appropriate hdd path for your pc.
I have recently begun contributing to the Folding@Home distributed computing project. Due to oversights in the application's design and to process the most advantageous work units, I need to run this command line app through wine. The application is very CPU/RAM intensive, but it does not put much load on the hard drive. It is multi-threaded and uses up to 100% of all 6 cores in my machine. I run it with a "nice" level of 19 with hopes that it won't slow down my normal desktop use.
Here is the problem... when running this setup, my system will frequently freeze for a fraction of a second and then resume. With the more complicated work units, this can happen 1-2 times per minute. During the freeze, the mouse will stop moving, videos stop playing, music pauses, etc. The system is completely unresponsive. However, each instance only lasts for a very short time. Since this happens so often, my productivity is negatively impacted (and it's very annoying).
I previously ran the native Linux version of F@H without this problem, but that was also processing much less complicated calculations. I have tried with wine 1.2.1 and 1.3.5 with the same results. The application does not have problems running on Windows. It has been suggested that the current Linux CPU scheduler is to blame, but is there anything I can do to resolve this now or work around it?
this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"
i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after
My LAN has 2 PCs installed, Ubuntu 10.04 and Windows XP. I run the server on Ubuntu, and client on Windows XP. Because I am doing stress test, so the client will keep sending tons of packets to server.
The strange thing is: After few seconds, the client program crash because of insufficient network buffer, the server is still ok. But after that I cant connect Ubuntu PC anymore until I restart it. And I check the router, the led for the Ubuntu PC is always ON (not blinking), look like it is jam already.
Am trying to set up a new system but am getting some strange behavoir. I've administered an Irix system before. I have opensuse 11.3 installed with gnome running. When i enter a bad user id in the windows login screen, the bad authentication causes the x window manager to crash and leaves the system in the ascii terminal mode login. I then have to login as root and do an init 3 , then init 5 to get the x server started again an get the windows login started. Has any one seen this behavior before and how can i fix this. Been hunting through /etc/X11/xdm to see what startup scripts could be causing this.
There is a tool appeared in repository called ktune; The purpose is to adjust some sysctl.conf settings to improve server speed on servers with heavy load. What is this tool for if one can achieve the same with the configuration file added to system startup? Or ktune is just such file?
I performed an update that has caused issues with my wireless. Errors relating to wireless firmware missing and consequently no internet connection.
I've been through this before with my 2008 macbook air BCM card whose firmware isn't included in installs. In the past I've manually installed the b43-fwcutter package an extracted some firmware... That doesn't seem to be working here.
I've used [URL]i ... cefirmware to troubleshoot. I have not been able to get b43 or wl to work.
I attempted to install the "firmware-b43-installer_015-14.1_all.deb" package; however it depends on wget to download and install "broadcom-wl-5.100.138.tar.bz2" from wlfinger.com.
So I manually installed b43-fwcutter and used it to extract the broadcom-wl-5 file referenced....
modprobe wl says wl doesn't exist and modprobe b43 doesn't seem to work.
Code: Select allsudo dpkg -i broadcom-sta-dkms_5.100.82.112-8_all.deb Setting up broadcom-sta-dkms (5.100.82.112-8) ... Loading new broadcom-sta-5.100.82.112 DKMS files... Building only for 3.2.0-4-amd64 Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed.
I tried something from broadcom that produced make errors "/lib/modules/3.2.0-4-amd64/build: No such file or directory"... I think this means I need some kernel development packages, broadcom says:
Code: Select allOn Fedora install 'kernel-devel' (Development Package for building kernel modules to match the kernel) from the Package Manager (System-> Administration-> Add/Remove Software).
On Ubuntu, you will need headers and tools. Try these commands: # apt-get install build-essential linux-headers-generic # apt-get build-dep linux
I'm having trouble install this stuff without the net and not sure installing generic headers and build-dep outside of apt-get is the way to go... linux-headers-3.2.0-4-amd64_3.2.57-3+deb7u2_amd64.deb has alot of dependencies that would take me a while to find and download.
I just did a fresh install of Squeeze with a KDE desktop on my computer. I use this computer to run an instrument in my lab. The instrument is connected to my computer through an ethernet card. Since my reinstall I cannot figure out how to get my computer and instrument communicating again. I'm guessing that I need to somehow tell my computer to connect to the device, but I don't know how. Here is my interface configuration:
[Code].....
I think my instrument is connected to eth2, which does not show any inet addr or Bcast ip, so I'm guessing that is a problem. How do I fix this?
I have a problem with my Debian squeeze system. After I have run some CPU-intensive application for a while the system becomes sluggish. Ok, maybe one would expect that. But. The system remains sluggish even after that process has been killed and then top shows high cpu usage from unrelated processes and a high %sy percentage as well. I don't really know where to begin solving this problem except I've checked that this is specifically related to (at least) CPU use as opposed to heavy memory use or IO (by running an application with low mem/no io but high cpu use). I am running the latest standard kernel from squeeze, 2.6.32-5-686. Also, thing is, I remember having similar problems with other Linux distros before, where for example gzipping a large file would cause the same. I did not have similar problems on {Net,Open}BSD, so a hardware fault seems an unlikely reason to me.
I followed this guide for my Acer Aspire One A150, and got wireless and suspend working fine:[URL]pendtoRAMThe only problem is that wireless is dead after resuming from suspend. I have to type:/etc/init.d/networking restart and after that everything works just fine and I get internet again.Is there a way to automate that process on resuming from suspend, so that I won`t have to type it manually each time?
I am running a recently built Debian 'Lenny' system 5.0.4.I used the gui install and asked for desktop/file server/ I created a raid 1 systemsing two similar drives.Finally I set up some samba shares to use from my (wife's) windows PC. I wanted to use PC names rather than IP adresses to access the shares so activated wins.My Debian system, called arcturus, did not appear in windows network places. After much trial and error and googling found that the nmbd service had stopped.'/etc/init.d/samba restart' reported nmbd not present, stopped smbd and then restarted both. My networking then all came to life.There is a Ubuntu forum discussion around this subject and the consensus seems that the samba daemons are starting before the network is properly established. I have installed a work-around by putting the restart line in /etc/rc.local.But I'm concerned that I have some kind of configuration error.The following is a section of my log.nmbd after setting logging to level 3:-
I'm having a really weird, annoying problem: approximately every 10 hours, like clockwork, my internet connection stops working. (Last time I had the presence of mind to check the uptime: it was 9 hours 48 minutes; this was maybe 5-10 minutes after it happened). My existing connections (IRC, etc.) keep working fine, I can access my home router's configuration page, and `ping` still works, but otherwise new connections invariably time out (whether it's a web browser, git/subversion, or whatever). I have found no solution to this other than rebooting.
I have a netgear WG11T. I'm using the drivers through ndiswrapper, and connecting through wifi-radar. Everything works fine, but if I take out my WG11T and then put it back in, it is not recognized; in fact, nothing in that port is recognized, until I reboot. How can I make my usb port less sensitive?
I am totally new to Linux and have a PC here with 128 MB Ram and a 10 GB HDD. It has Windows Millenium installed but I presume this will be wiped during the install process if I so wish.,
I am part way through the install using CD's and have just chosen my required alnguage and then keyboard layout. The next option is asking me to choose what device drivers to load and most appear to be HDD Drivers. I haven't a clue what to choose here?
I have a Linksys AG300 "Adsl gateway" router/modem. When I download files with Iceweasel, the connection to the internet drops out (the internet connection light goes off, downloading stops). It's been happening for a while with Etch (and whatever version of Iceweasel Etch has), but I've today installed Lenny and it is still happening in Lenny.
My ISP said it could be a problem with the phone line because my computer is connected to an extension, but it does not happen at all if I download with Opera, and I would have thought that the browser wouldn't matter if it was the phone line or something in the router/modem. I'm not that fussed because I can use Opera to get my downloads, and the new version of Iceweasel will let you continue on if the download stops so all is not lost if it stops (it's just annoying). I'd be interested if anyone has any ideas as to why this happens. It seems to be an "Iceweasel thing".
I downloaded the full install of Fedora 10. I burned the DVD and it booted okay. Going through the startup stuff, select language, keyboard, ect and then I choose the dvd as the source of the image. Then I get "no driver found" and gives me the option to choose from a list of drivers or to use a driver disk. I saw something in the forums about someone having the same problem but theirs was a video card issue. On the list of drivers it looks like they are network card drivers. I have no idea what to do. I am using a NVIDIA Geforce FX 5500 if that helps. I also did not verify the iso, though wouldn't it not boot at all if the iso image was broken?
I've running ubuntu 11.04 on my samsung 900x3A notebook and have a problem using the touchpad: I've configured my touchpad using "GPointing device settings", but everytime I reboot my system I've to start "GPointing device settings" manually to apply the settings for the current session. Is there a way to do this automatically?
Secondly I've the following problem: I cannot use "click and move" with my touchpad. For example, when I try to move a window around: Normally one would click the left button, hold it and move the window via touchpad. But every time I click the left button, any other movement with my touchpad is disabled. Is there a way around this?
I have enabled USB -OTG as Both Host and peripheral. USB - OTG host mode is working fine but USB - Device mode is not working...I'm unable to load g_file_storage.ko,I get below error:
I'm unable to login to my Kubuntu Lucid. The login screen takes my password, blanks, then returns me to the login screen. I'm getting some graphics errors when running from recovery mode as well as the no space left on device error when attempting to start x from the terminal. Here are some outputs: When starting from recovery mode, selecting failsafeX from the Recovery Menu:

I've come to the conclusion that my root partition is full, but I'm not sure how to clear space, or how much to clear once I work out how to do it. I removed a few packages with apt, but it doesn't seem to have any effect. df -h shows that root is 100% full, yet it has 3GB free. I've grown comfortable with Ubuntu in the couple years I've been using it, yet this level of problem-solving is a bit nerve-wracking to me. I've been considering reinstalling (this machine is running Lucid upgraded from Karmic and Jaunty and has a few oddities), but I hate the idea of being forced to reinstall because I can't overcome this problem. If you need any other information or outputs from terminal commands, I'm happy to provide it.
64bit Slack doesn't recognize my ethernet device. ifconfig -a show no eth0. It's an onboard nvidia MCP55 ethernet nic. Never had this problem using 32 bit Slack.
When I try to modprobe forcedeth I get the following error:
repeats those two statements 3 times
I just recompiled my kernel with every possible 10/100 ethernet device included in the modules. Still no go.
I just got a new graphics card (all specs below) and when I start up the computer, it loads the BIOS, then says it's loading grub 2, then says, "Initializing gfx code..." and hangs there forever. How can I diagnose this and find out if the card will work with my computer and opensuse 11.1?
Complete n00b here. I am running openSUSE 11.3 and trying to load drivers for a network card. When I try to make install, I am getting this error:
Code: Makefile:69: *** Linux kernel source not found in any of these locations: Makefile:70: Makefile:71: *** Install the appropriate kernel development package, e.g. Makefile:72: *** kernel-devel, for building kernel modules and try again. How do I install the kernel-devel?
