Fedora Hardware :: Processors Are Not Active And There Is No An Obvious Process That Captures Cpu?
Apr 25, 2011
I just install fedora 15 (64bit) on my Toshiba Satellite L550 laptop.I realise a problem with my fan. It is ON almost allways (90% of the time my laptop is on).My processors are not active and there is no an obvious process that captures my cpu.I had the same problem on fedora 13 and 14 too. I hoped that they solved it in 15.... but... this was not true . When I run it from inside Windows 7 (from a Virtual Machine) it works fine! I was searching to the internet to find a solution (for days) with no luck!Is it a compatibility problem between my CPU and Linux kernel?The problem is very annoying indeed and prevents me for using fedora as my default OS with or w/o A/C.I must say that the same problem exists in ubuntu 10 too
I have 2 CPU 8 GB RAM server running MySQL & HTTP server with apps using LAMP architecture. Since last few days we are having some performance problems.While looking at the problem i came to know both mysql and http are almost taking 100% cpu time of a single processor and the second processor is free. redirecting the mysql load to one cpu and http load to the second one? Is it possible? If so how to do it?
Has anyone experienced random wireless dropouts? Like one minute, you are connected and then not, with no obvious reason as to why it happened, just network manager popping up requesting a password to reconnect.
Today my eth0 has intermittently shut down a couple of times without obvious cause from router or modem which appear normally lit. This happened a month or two ago soon after an update and them went away. I have unchecked ssh in the firewall settings as it is not needed but this has never been a problem. In the block of code there should be one attempt to graphically restart eth0.
I have run into a problem with my desktop using roughly 50% RAM (w/o buffers or cache) while running a limited set of applications (fbterm, tmux, weechat, ncmpc, rtorrent) on the command line. This usage only increases roughly 5-10% when starting X (an addition of xcompmgr, awesome wm, zim, parcellite, 2x conky (one replacing root-tails functionality), plus firefox and other apps that may or may not be running from time to time). (h)top is reporting programs only using roughly .1-.2% per proccess and roughly 100 processes (current look at top shows 120 processes, only 32 of which are registering any usage over 0.0%) The RAM usage when in the console (which I will add is about 150MB after boot) is totally unreasonable and I need some direction on trying to find out what is using all of this RAM.
System: Distro: Arch Linux RAM: 2G CPU: AMD 64 x2 4800+ HDD: 3x WD Black 750G (RAID 5 on partition 2 (swap) and 3 (root), RAID 1 on partition 1 (boot). LVM over root partition) GPU: Nvidia 8400 GS
I've run into a sort of catch 22.I installed wireshark via apt-get on my Eee 1008HA, but when it is launched, it does not allow any capture interfaces. I think this is because the shortcut created in my applications paneldoes not start it as root.So I went into terminal, typed in "sudo wireshark" and it popped up, as root. I was then able to capture on my wireless interface. However, if I try and specify my home folder as the location for the capture to be saved, I get an error that permission was denied, which seems odd since the process is running as root and should be able to do pretty much whatever it wants. How can I get wireshark set up so I can both capture _and_ save the .pcap files I generate? I'm running karmic koala, the full output of uname -a is: Linux ruckus-laptop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux.
I am trying to use screen captures in compiz but they are garbled and unusable. I am running ubuntu 9.10 on a dell latitude D520. I attached a copy of one of the screen shots.
I have an ubuntu PC with 2 nics, 1 for the internet, the other one should be to connect other computers an analyze the network traffic with Wireshark. How do I configure this 2nd nic to achieve this.
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process
I m trying to develop an application to block packets(using c++)(like a firewall). i have tried pcap library , but it doesn't block packet just captures them.
how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?
I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.
When working in an XP VirtualBox I can't use Alt-Tab to switch to my Linux Apps as VirtualBox captures the keys for Windows. So I tended to make a lot of use on the Application list on the old System Tray/Taskbar. I could click on the application's entry in the taskbar and that application would come up. When I needed to return to the Windows App, I clicked again and the application would then minimise so I can see the Windows app. Also I have been using the SUPER button in conjunction with 'E' to raise the Home Directory (just to keep it consistent with Windows).
I have an Acer Aspire One Netbook, and I have the Ubuntu 9.10 Netbook Remix installed. I have tried using Cheese to capture video and it captures maybe 2 seconds of movement, then goes black and/or the image freezes. I can take photos just fine, but video capture seems to be impossible. Any help?
I was previously using kernel-huge until a slackware update caused some problems for me, so I switched over to kernel-generic but now I'm wondering if it uses both of my cpus on my dual core processor.
I have a server with 48 cores, 8 6-way Opteron CPU's. Ubuntu Server 9.04 only sees 32 processors. Is there a limit on the number of cores/processors that the server will use? Windows 2008 on the same server sees all 48 cores and the so does the BIOS, so this is unique to Ubuntu right now.
Just installed centOS 52 x86_64 on a Core 2 Duo (E6750). From the /proc/cpuinfo I see that only one processor is detected. Any parameter on the BIOS to be changed?
i recently purchased an i7 laptop and really don't want 8 cores on my bar. i remember there being a file that controlled this but i believe it wasn't writeable.
I just installed the latest version of Ubuntu 10.04 LTS, and am wondering if support for my dual AMD processors is built into the generic kernel, or do I need to compile a custom kernel? I have an HP tx2-1025dx touchsmart.
Are the 64 bit Lucid disks suitable for Intel i5 processors? The AMD64 part is making me think not.I already have the 32 bit version running very nicely - should I have gone 64 bit though? What are the advantages/ disadvantages, and why does it say not recommended for daily use next to the 64 bit download? As far as I understand you can run 32 bit binaries without problems on a 64 bit install.
I want to learn board specific package(BSP) for ARM processors under LINUX platform, please guide me "from where I need to start, what are the things I need to purchase" hoping to hear from you soon.
when I start my application it creates a message queue and forks a process. The child process reads multicast packets from the network and writes to message queue. The parent process reads packets from message queue and compares source ip and sequence number (it is part of payload) with last 64K packets received to see if it has received a duplicate packet. I am using message queue as a buffer because I do not want child process to drop any packets while it is comparing it with previously received packets. The message queue is large enough to contain 64K packets. To compare the old packets I am using array of structures as circular buffer. During a spike I may receive 100 - 120 packets per milli second.
When I run my application, the parent process keeps up with the child process, I can see that with "ipcs -q". After about 30 seconds it cannot keep up and the size of message queue keeps increasing until it is full. When I run "top" I can see that one CPU/core is hundred percent busy while other 7 cores are idle. It seems that both processes are running on same core and the child process gets interrupts everytime there is a packet on the net and starves the parent process.I am running RHEL 5. The system has 24GB memory and my application is the only application running on it. It is a HP G6 server.
In my Open-Suse server I have a script, where makepasswd output(by default it generates similar passwords: cGyTbqpr, tpJ1LA, 33EXdo) is redirected to mkpasswd(which uses DES by default) in order to generate salted hash of this previously generated password. I would like to test the strength of this system. I have a quad core CPU, and if I start John The Ripper like this(I want to use -incremental:all flag):
john -incremental:all passwd
..only one core is utilized at 100%. Is there a possibility to make all four cores to crack this password? Or is this possible only after reprogramming John The Ripper? Or what is the algorithm for generating passwords with with -incremental:all flag? I mean if John generates passwords randomly in brute-force mode, then it's smart to start four different John processes simultaneously because then one of those four will find the password firs
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69 real 9m54.886s user 0m5.536s sys 0m1.740s $ ls -l test-32000.wav -rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

When the day Fedora13 was released, I downloaded one and installed it. After runing the command:
Quote:
yum install mesa* xorg* fusion* compiz*I can't active 3D effects. But on fedora 12, it takes effect by runing that command. My graphic card is Ati pro 2600 It is maybe the bug of fedora 13. Post added at 05:44 AM CDT Previous post was at 01:23 AM CDT
