I have installed CentOS 4.2 on an AMD based machine using the ATI chipset (xpress 200) and I am having issues with it. It seems to be a very Linux unfriendly chipset. I have looked at the ATI proprietary drivers but they seem to be for video. My problem is the IDE channel on which you cannot enable DMA. There is serious clock slew also as well as nic issues. There is supposed to be an ATI

Hi I have a compaq R4000 with the 2.4GIG AMD 64 bit. 4000+ rated. proc cpuinfo reports cpu Mhz as 997.481 Do I have to run the 64 bit version to have things run correctly? I just have the normal 4.2 loaded at this time. The laptop seems slow for 4000+ as reflected by the cpu Mhz also. Any thoughts on running the 32 bit version of 4.2 vs the 64 bit version of 4.2?

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

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

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

I have a desktop unit with a sempron 2500+ to play with. doing "more /proc/cpuinfo" indicates cpu Mhz as1044 not the 2500 I am familiar with cpuspeed. doing ps ax | grep cpuspeed resulting in nothing. I did service cpuspeed start. No errors reported. ps ax | grep cpuspeed resulted in nothing. I was going to do "killall -SIGUSR1 cpuspeed" to attempt to get 2500+ cpu speed. I

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 to the list, I am trying to find a way to painlessly move structured data back and forth between R and Matlab (also Octave). For this purpose I found the R.matlab package great help. I wish to use a Matlab -v6 MAT file as an intermediary format, because it is well read by both Matlab and Octave. It is also well read by 'readMat' function in R.matlab package, but that is where I run

what is the correct way to set an AMD64 CPU into performance mode at boot time? I have tried doing service network cpuspeed start, then killall -SIGUSR1 cpuspeed and this works but I cant get it working this way at boot. I have set chkconfig cpuspeed on but that didnt seem to help. I just want this particular machine to boot in performance mode and stay there. Jerry

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

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

After a couple hours last night.... doing a "killall -SIGUSR1 cpuspeed" bumps up the /proc/cpuinfo information for cpu mhz to 2393 Mhz. I did notice a little increase after that. However, the machine is still sluggish. I did a "hdparm -c 1 /dev/hda" but really did not notice any difference. I tried to download fglrx64_6_8_0_8.16.20-1.x86_64.rpm from ati (also 8.20.8) and get

I am trying to install x86_64 on a compaq r4000 laptop. booting the CD I have tried text mode only and graphicaly mode. I see the normal stuff flying by and I just get a black screen (in text for graphic install). I have tried linux acpi=off apci=off nousb nopcmcia linux noprobe all result in the same black screen. Once the screen goes black the CD is still being accessed but the screen is

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, cpuspeed did not start on all my systems. CentOS 5.4 x86_64 /etc/init.d/cpuspeed start (nothing happen) Something is missing ? Thanks in advance for any idea.

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

Hi, we bought some machines with 2 x quad core Xeon E5405 processors and installed centos 5.3 on them. My problem is that I can't get the cpuspeed service to work. No driver seems to claim responsibility for the throttling and the fallback "modprobe acpi_cpufreq" in the cpuspeed init script just yields a "No such device" message. According to the acpi information the

I finally got the time to try the new kernel. recompiled it and now the compaq r4000 seems like an amd 64 4000+. THe issues of sloowww ness seemed to have gone away.

Anyone tried installing centos 4.2 on an compaq R4000? The CD boots, I hit enter, starts uncompressing the kernel detects my disks (last thing I see) then the screen is BLANK. I tried "linux text" also and exact same thing happens. THanks, Jerry
