similar to: cpuspeed: missing drivers ???

Dear all, The cpufreq modules have been distributed in Centos. But recently, I met a problem when I tried to test the power-related applications. The module can not be modprobed in kernel notwithstanding releated with Centos distribution. The messgae thrown out is: ------------- dump of screen ------------ # modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found

I''ve upgraded to linux 3.10 and enabled extended inode refs and skinny metadata extent refs with these commands: btrfstune -r /dev/sdc1 btrfstune -x /dev/sdc1 Since then, I have "WARNING: at fs/btrfs/backref.c:903 find_parent_nodes+0x616/0x815 [btrfs]()" showing up like crazy: # grep -c "WARNING: at fs/btrfs/backref.c:903" syslog 181819 That''s after just

Having done a current checkout, creating a new FS and running iozone [1] on it results in an oops [2]. remove_suid is called, accessing offset 14 of a NULL pointer. Let me know if you''d like me to test any fix, do further debugging or get more information. Thanks, Daniel --- [1] # mkfs.btrfs /dev/sda4 # mount /dev/sda4 /mnt /mnt# iozone -a . --- [2] [ 899.118926] BUG: unable to

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

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

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 -

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, 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.

I''ve enabled "extended inode refs" and "skinny metadata extent refs" with btrfstune. Then, I''ve tried running "btrfs filesystem balance" - unfortunately it segfaulted. (not sure if I should run balance operation after using btrfstune with -r and -x)? This is with 3.10 kernel with "Btrfs: make backref walking code handle skinny metadata"

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, Each time i try tou use vhost_net, i'm facing a kernel bug. I do a "modprobe vhost_net", and start guest whith vhost=on. Following is a trace with a kernel 2.6.37, but i had the same problem with 2.6.36 (cf https://lkml.org/lkml/2010/11/30/29). The bug only occurs whith vhost_net charged, so i don't know if this is a bug in kvm module code or in the vhost_net code. Feb

Hi, I tried very promising btrfs to test it a little and I experienced a little bug in implementation. I''m not sure where the bug lies however this works quite well to reproduce the problem: dd if=/dev/zero of=mountme bs=4k count=100000 dd if=/dev/zero of=mountme2 bs=4k count=100000 mkfs.btrfs mountme mkfs.btrfs mountme2 mkdir loop loop2 mount -o loop mountme loop mount -o loop mountme

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

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

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
