Fedora Hardware :: CPU Clock Speed Not Being Correctly Detected
Dec 24, 2010
I'm a very new Fedora user, and I've stumbled upon an issue which I can't seem to resolve. Having had a good look through similar issues, I'm still stuck.I have a Fujitsu Siemens Amilo M3438G laptop, upon which I've recently installed Fedora 14. It seems to work great apart from one thing; CPU speed. The processor in the laptop should run at 2GHz. At the moment, it's running at 600MHz, and I simply can't get it any higher.
I've played around with power profiles a bit, not really knowing what I'm doing, but the issue seems to be that the CPU is somehow reporting to the Operating System that it's top speed is 600MHz.The BIOS on this laptop is very limited, and doesn't give me any clocking options whatsoever, so I can't manually set things like multipliers, etc.So, I guess my first question would be - how does the OS find out what the processor speed is, and is there any way of manipulating the top speed? Surely there must be a way for Speedstep compatible processors to exceed their initial clocks?

When I boot my computer, I can see dvd-rw drive detected correctly, though 9 times out of 10 it does not get detected by OS - drive's icon is not present in nautilus hence I cannot access any cd or dvd. Although when I restart a computer and try to boot from cd or dvd - it works perfectly, then after coming back to the os the cd/dvd won't be accessible. I a have Fedora 13 installed from the DVD ISO.

Today my desktop reverted to 1024x768 resolution immediately after init. I tried changing it back but only 1024x768 and 800x600 are listed as supported in the display settings, even though my monitor supports resolutions of up to 1360x768. Rebooting the system did not solve the problem.I'm running Fedora 15 x86_64 on kernel 2.6.38.8-35 with the proprietary nvidia drivers of version 275.09.07. My monitor is a Samsung SyncMaster 933n. nvidia-settings is apparently not detecting it correctly, it thinks I'm using a CRT monitor.I was actually in this exact same situation a few months back, but it kind of went away on its own, so I didn't mind too much. So, what could be causing this, and what can I do?

I just installed conky and followed a set of instructions to get the NightDrive theme setup. Everything looks alright except that some of the text and the clock are off. Been experimenting with different values but I am not really knowledgeable in coding as of yet. Anyone give me an idea of where in the conkyrc I can adjust the x, y for the clock?

I have this problem for a while but didn't notice it until lately(i did reboot the machine for few months). Now that i reboot it frequently i notice that the clock is always not what is supposed to be. I'm in Toronto, Canada so it should be GMT -5:00. Sometimes it shows GMT-6, sometimes -10, now is GMT -11. Anyone would know why i have this issue? I'm running Suse11.1 on a 64 bit. My laptop which runs on 32 bit is working fine.(well probably different versions for kernel and kde.(whatever was in th repository to be updated i updated)
2.6.27.39-0.2-default
Version 4.3.4 (KDE 4.3.4) "release 2"

I recently installed 10.10, and I have not been able to get the gnome panel clock to work correctly. I will set it to the correct time, but every time I reboot it will be wrong by several hours. I have never had a problem in previous versions and I have always set the clock by right-clicking on the clock -> Preferences ->Time Settings. Am I doing something wrong or is there an easy way to synchronize with a time server?

I am using FC 2.6.31 kernel and am tying to bring up a SDIO network card. I am not able to change the SDIO clock speed which is by default 50MHz.I have to bring it down to somewhere around 25Mhz to make the card working smooth.How can we set the host clock speed from our driver in this kernel.

I am new to the forum and new to Linux.
I am trying to explore if Linux can be run on a multicore platform when the max frequency of one the cores is less than the others.
please give me some pointers or let me know if you have tried such HW configuration.

I try to setup a HPC cluster with CentOS 5.5. But now there is no Internet connection available in the room where the hardware is located so I set up ntpd server using synchronization with local clock (maybe I do something wrong). Here is my ntp.conf file on a master node (the master node has IP 10.0.1.1, a file server has IP 10.0.1.2 and compute nodes are 10.0.1.3..10.0.1.11, comments are omitted):
restrict 127.0.0.1
restrict -6 ::1
restrict 10.0.1.1 mask 255.255.255.255 notrust[code].....

I am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).

I just installed oS11.3 on a new Aspire Revo R3610 which has the Intel Atom 330 chip and Nvidia ION graphics.
I noticed that the CPU is always running at 1600Mhz and doesn't throttle down when there is no load. Do the Atom cpus not throttle down or is there a setting in 11.3 that I can change?
I installed the 64bit of oS 11.3.

I had a working 10.04 installation and everything was good, then i compiled my own kernel and screwed things up. So I reinstalled and installed my graphics drivers. But Ubuntu can't seem to get my correct resolution. So I am stuck at 1360x768.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

Any time I try to install software building it from source when I run make I get a waring "Clock skew detected. Your build may be incomplete". Some software build successfully and run normally after install but some build tasks are failed for example when I try to build RPM's via 'make rpms' for BLCR I get an error message about invalid date in changelog. But the system date seems to be right. I suppose I have invalid settings of NTP.

I'm using a very simple conky script to diplay the date and time on my desktop. I've noticed that he conky clock is a few seconds early compared to the time displayed in the right hand side of the top panel (Natty). I guess both displays are based on the same "internal" time, so I'm left wondering how this could happen, and how to sync back the clocks.
It seems that Conky is in sync with the system date, while the panel clock is 2 seconds late (on my system). Checked with while true; do date; sleep 0.1; done

I had cloned a centos 5.6 installation from virtualbox virtual machine to physical box. Everything work fine. However, the time showing in os using date command differs from bios time by roughly 4 hours. I am running ntp services which sync the time with another centos server on the network. It appears that some services are using virtual clock and some use physical clock. How do I get rid of virtual clock and only use physical clock?

Ubuntu 64bit. The sound system works and plays noises correctly when I test the speakers in sound preferances. The internet BBCi player(Radio) plays sound correctly. Banshee & Rhythmbox try to play music files at double, or more, speed with no sound output. Spotify Linux version also tries to playback at double speed with no sound output. Media Player attempts to play music files at high speed. Media player plays the Video and audio tracks at high speed. VLC Will play the video at normal speed but with no audio.

When installing I perhaps mistakingly told Fedora it should use the BIOS clock and now it shows the wrong time, 1 hour ahead of my time-zone GMT+0. If I try and go to the preferences and set the time the 'Advanced Options' one of which I need are grayed out, I need the 'Use local time source' option to be unchecked. Could somebody tell me a workaround or the command-line commands to tell it not to do this anymore?

i both have the same problem, i'm trying to burn my images at 4 or 8 speed, but ubuntu 10.04 says that the hardware does not support that kind of speed and switch up to 16 speed and more. i know it can burn at low speeds, at least in windows, it is a bit strange that fast burning is okee, and slow not, what can i do to prevent this? i don't wanna burn to much errors on my discs

I've been running a fedora server for over a year now, and has seen some very strange issue, that really make it uncomfortable to use, and that I cannot manage to solve easily.
The problem is as follow : sometimes (every 20-30 minutes or so : this time is quite random), the server completely hangs.
I'm using it mainly remotely, through ssh and nfs. What I see when it "hangs" is the following:
-no ping response
-nfs stalled
-ssh sessions hangs (for example, if I run a "top" command", it just isn't updated anymore
-disk activity led stays completely off (in normal activity, it is almost always blinking, even due to "internal" server activities, so network disconnection doesn't explain that either)
The most strange thing is that, to resume it, I basically have 3 options : wait (sometimes few tens of seconds, usually between 2 and 4 minutes!), just hit a key on the keyboard!, or do something like un/plugging any king of usb peripheral (which makes me think of some interruption mechanism that is stalled).
When it "wakes up", I see my "top" session over ssh suddenly being quickly updated hundreds of times (for all it has not received during the "pause"), ping says that the packets have actually all been received (with long times, for example, packet 1 : 80xxxms, packet 2 : 79xxxms, packet 3 : 78xxxms..... packet 79 : 1xxxms, packet 80 : 0.xxxms), the disk is quite overloaded for a few seconds, and everything is back at normal!
Furthermore, I think this i related, but my clock drifts for few hours per day (3 holding minutes every 20-30 minutes makes me think there is some relation!)
I tried to set up ntpd to compensate it, but sometimes the suspensions are just too long, and I ended up with
Code:
Nov 27 01:22:36 server ntpd[699]: 0.0.0.0 0617 07 panic_stop +1203 s; set clock manually within 1000 s
and ntpd dies...
You'll ask me to have a look at the log, which I did by
Code:
But when the suspension happens, there is absolutely nothing new in all those files!
Version information :
Code:
I said in the title "F13-F14", because I already had the problem with F13, but after some time it disappeared (I may have changed some configuration, I have to admit...). I still have a backup of the "/etc" tree of that "working" F13.
The hardware for F13[working] and F14[not_working] is the same : Phenom II X4 on an ASUS M3N78 PRO, data on raid 10, system on separated SATA disk, 8Gb RAM, some qemu vms running (between 4 and 6).

I have dual boot on my comp. Windows XP and Fedora 11 Now in both systems time zone is set to Belgrade ( which is my time zone), but when I setup clock in fedora to be, let's say 16.15h, then when I swich to windows it says time is 14.15h. When I setup in windows on 16.15h, and I swich to fedora, it says time is 18.15h. So I can't get accurate time on both systems in no way.
