    [ubuntu] Re: Unclear high CPU usage

    Actually, they don't disagree by much. Top shows the 1 minute load average as 2.85 or 285%. The other numbers are over a much shorter interval and out of all 4 CPUs, so the total of 56.3% * 4 =...

    Re: Linux 5.8 Kernel

    Over on the devleopment sub-forum, we always have a thread going for every kernel release candidate series. You can review the 5.8-rc series one to see what issues came up and what we learned during...
  3. [SOLVED] Re: LUBUNTU Where is configuration cpu power profiles ?

    There is no such driver as amd_cpufreq, that I am aware of.
    You are probably using the acpi-cpufreq CPU frequency scaling driver and the ondemand governor by default.
    I already showed you how to...
  4. [SOLVED] Re: LUBUNTU Where is configuration cpu power profiles ?

    Yes there is, I think. I have absolutely no use for such things.

  6. [SOLVED] Re: LUBUNTU Where is configuration cpu power profiles ?

    It depends on which CPU frequency scaling driver you are using. Do, and for example:


    $ grep . /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver...
  7. Re: help need with a dns server bind9 preferably

    I run bind9 on my LAN. I also run a dhcp server on the same computer. Visiting computers acquire a dynamic IP address, which includes which DNS to use. Then they can access my web site by name. If...

    Re: Looking for xtables-nft package

    Just curious how you made out in the end. The latest mainline kernel seems to have switch to default to nftables, which caught me off guard. I am wanting to build a new 20.04 server based box for my...

    Re: Kernel 5.8 RC (Release Canidate) series

    It seems the default for iptables/nftables was changed. Couldn't run my VM's either. Do:


    # update-alternatives --set iptables /usr/sbin/iptables-nft
    # update-alternatives --set ip6tables...
  10. Re: Request for help/test - Intel Processors power log bits

    The point with all of this is that I do not know if it was "real" or just the bits started up that way. In my case, and to the best of my abilities, the sticky power log bits were not real. I...
  11. Re: Request for help/test - Intel Processors power log bits

    I am attempting to acquire evidence that several systems startup with some of the logging bits within the processor itself set. These sticky bits would normally indicate that some event, say some...

    The Ubuntu mainline build process appears to also build a lot of, if not all of, the tools and tests and such. It appears to fail while attempting to link...
  13. Re: copy large number of files from macOS to Ubuntu

    Don't leave us wondering. Did it finish?

    By the way, that is exactly what I did in post #9 .
  14. Re: Request for help/test - Intel Processors power log bits

    Thank you very much. So you have either had a Thermal event or the bits powered up that way. Interesting. Do they clear and stay cleared if you run the other program, msr-pwr-log-reset? Which I...
  15. Re: copy large number of files from macOS to Ubuntu

    There is likely little value added with this reply. I was just interested is all.

    On one Ubuntu 20.04 server I created 150,000 files, each with 1048576 random bytes, for a total of 150 Gigabytes....
  16. Re: Request for help/test - Intel Processors power log bits

    Yes (and as Cavsfan already replied). It is needed and I don't check if it is loaded. I edited my edit in my original post.

    Thank you very much for trying.
  17. Re: Request for help/test - Intel Processors power log bits

    Hi Cavsfan,
    Thanks so very much for doing this test. So you had no log bits set directly after re-boot, and did not have to use the bit resetting program at all. O.K. that is very useful...
  18. Request for help/test - Intel Processors power log bits

    Hi All,

    I am looking for users with modern (Sandy Bridge and newer, 2nd gen and newer) Intel processors willing to do a simple test, and report the results on this thread.

    It seems that some...

    Well, the same information is also in /var/log/kern.log, available to anyone. One problem I observe with linux is no concern for backwards compatibility. These type of changes create a cascading ton...

    Kernel 5.8-rc5 is available, but still with the incorrect files names.
    If someone wants to go on IRC and ask about the file names, please do, referring to the last time.

    So 2 watts in sleep mode, seems high, but reasonable to me.
