similar to: CentOS 5 + Xen + cpuspeed

[I sent this to the RHEL4 list - but maybe someone on this list knows more] I have a number of dual CPU and dual CPU/dual core Opteron systems that are used as compute servers. In an effort to reduce power consumption and reduce heat output, I would like to make use of the PowerNow! capabilities to clock back the CPUs when the machines are idle. These machines are running a 2.6.9-42 RHEL4 kernel

One problem I've discovered in cpuspeed is that there are drivers missing: # cd /lib/modules/2.6.18-194.8.1.el5/kernel/drivers/cpufreq # ll total 72 -rwxr--r-- 1 root root 14408 Jul 1 21:40 cpufreq_conservative.ko -rwxr--r-- 1 root root 16168 Jul 1 21:40 cpufreq_ondemand.ko -rwxr--r-- 1 root root 7624 Jul 1 21:40 cpufreq_powersave.ko -rwxr--r-- 1 root root 12524 Jul 1 21:40

Hi all, I think I've spotted a few stupidities (bugs) in the current version of kernel-utils (kernel-utils-2.4-13.1.80). I'm sure these are all propagated from upstream, but I hope someone could have a quick look to verify this and see if we either can push complaints upwards, or provide local fixes. The kernel-utils package provides several 'kernel-type' functions -

Hi, Here'a a question - is it possible to compile a single module (distributed in the kernel source tree) for the current CentOS kernel (2.6.9-5.0.5) without recompiling the entire kernel and all other modules. I basically need reiserfs3 (nb. why is it disabled? it's a module, you use it, it doesn't wreck anything...) and I don't really want to change the rest of the kernel, and

From: Maciej ?enczykowski <maze at google.com> This adds a new setting: KBUILD_REPRODUCIBLE If it is non-empty, ar and ranlib will be called in such a way that timestamps do not affect the build output.

After upgrade my laptop, I discovered a low performance on it. The laptop is a 2,73GHz Intel centrino and from some kernels versions to now, it had a good performance, the cpu scaling worked fine. Now, I discover that forcing in /etc/sysconfig/cpuspeed the governors and/or max/min speeds, it don't want to run more quickly. The laptop boots fine with the correct speed (usual speed), but when

Hi, I've got a box with CentOS 4.2 x86_64 which had no DHCP access for a few hours, now I can't ping it (I'm pretty sure the box is still up). I expect the DHCP lease has timed out and the box has lost it's IP, I was expecting it to reacquire it once the DHCP came back up (configuration problem) - but no luck. Is this a known problem? Any solution/workaround? (for now or for

A small patch (attached) to the ogg123 source (dec 15 nightly build from CVS) that implements ranged playback a la: ogg123 -r 12:10-13:00 file.ogg to playback 12m:10s-13m:00s fragment from the file.ogg soundfile. Usage: ogg123 -r hours:minutes:seconds.fraction-hours:minutes:seconds.fraction anything can be pretty much omitted (within reason) [although it does not support hh:mm:ss.hh- ]

Dear All, I have one centos box ( centos 4.0 ) which is connected to MSI wireless router....... And which is connected to my ISP MODEM. I incorporated wireless router so that I can use my laptop from any of my rooms. Now this Centos 4.0 box is my home server machine. The MSI Wireless Router has DHCP server enabled. Wireless router has provided each address to my machines basically internal IP

It appears as cpuspeed is not running on my centos 5 box(s). One is a biostar motherboard Am2 6400+ the other is Asus am2 4800+. If I do "service cpuspeed stop" it says OK, If I do a "service cpuspeed start" is says OK. However at no time is cpuspeed running. /proc/cpuinfo only shows the cpu running at 1000 Mhz. If I manually run "cpuspeed -C & " I now have

I've been playing and comparing frequency scaling between AMD and Intel CPUs yesterday and there seem to be great differences between AMD and Intel and some gotchas. This is all on CentOS 5.2 with latest Xen kernels (which are supposed to be powersaving-enabled since 5.2). AMD: It seems once I get the AMD CPU to use the ondemand governor it works very well and very efficiently. But this

We are using CentOS-4.3 (x86_64) with Opteron servers, and noticed a problem with cpuspeed: If we reboot by doing "# reboot" or similar from a shell, the boot will hang not long after cpuspeed starts. The machine freezes: ctrl-alt-del doesn't work, and only pressing the reset button or a power cycle will restart the machine. If we reboot from power-up or by pressing the reset

Hi, Not meaning to rush you folks (you're doing a great job). But I'm about to install/clone 4 computers with Centos 4. When can I expect 4.2 to be out (in DVD format preferably)? As in, is it worth waiting and saving myself the later hassle extra downloads? [I don't actually have 4.1 DVD's, just 4.0, so I pretty much have to download the DVD.ISO anyway] Cheers & Thanks,

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default

Hey, folks, Sometimes my workstation bogs down... slows to a crawl. Using gkrellm, it's obvious the CPU is the laggard. The top utility confirms: the load average gets up over 4 at times. But this occurs when cpu stepping pegs the speed at 600MHz. This processor is capable of 1.5GHz and when it's allowed to run at that speed, the load average is under 2, which is fine. So the

In older version of centos there was cpuspeed -d running that controlled current speed. In centos 5 it is set for on demand and cpuspeed is not running. I can startup cpuspeed and send it a signal SIGUSR1 to go full speed. This works. However, What is the correct or prefered method to control the cpuspeed in centos 5? THere are times when I want to tell the machine to go full speed and
