    HP NX6125 very slow with 64 bit FC4

    We have purchased 4 * the new NX6125 AMD laptop from HP.

    The install of FC4 x86_64 takes 5 hours.
    Once installed it all runs slow - e.g. 10 seconds to launch any application such as a terminal window.

    The same machine running FC4 i386 has no problems the install took less than 1 hour.

    Any ideas what is the problem ?

    here are more details:

    AMD Turion 64
    1.5GB RAM

    at least 2 of these machines show this beahviour.
    Installing in text mode doesn't help.

    ATI Radeon mobile x300 - not recognized so VESA driver used.

    Connexant sound - autodetect finds ATI but this doen't work.

    Mouse tracking is erratic under both KDE and Gnome.

    Screen frequently freezes requiring a mouse movement to redraw the display.

    System monitor shows 80% CPU usage even when nothing else is going on. The system monitor process is shown as using the CPU.

    also sometimes HAL daemon fails
    and cannot find time servers

    clock shows random times


    At boot these errors are shown:

    Error sending line request (invalid argument)
    Error sending line request (invalid argument)
    There was an error in line 5 of /etc/audit.rules

    Get a popup from Konqueror saying
    The process for the file protocol died unexpectedly.

    Next 2 posts are extracts from the messages file showing boot up.
    Let me know what else I need to do to debug this

    Thanks

    I believe this is due to CPU throttling.

    This is usually set to 87% even though the machine is plugged into the mains.
    If you reset the throttling file to have a value of 0, the performance improves.

    However within 5 minutes the throttling is back at 87%

    What processing is doing this ?

    CPU scaling does not seem to come into play as the speed stays at 1795

    We have disabled the power saving option in the BIOS.

    Maybe these message sin the message file are relevant

    Can anybody help ?

    I think I've fixed it with the help of a colleague. The thermal trip settings were all set to 16 degrees C so throttling always occurred.
    I have set the values to a higher level by modifiying the /etc/init.d /set_thermal file to contain these lines

    echo "95:75:75:65:60:55:45">/proc/acpi/thermal_zone/TZ1/trip_points
    echo "100:85:85:60:55:45">/proc/acpi/thermal_zone/TZ2/trip_points
    echo "100:55:55:60:55:45">/proc/acpi/thermal_zone/TZ3/trip_points

    before the line
    touch /var/lock/subsys/set_thermal

    Seems to be OK

    I have submmitted it as bugzilla bug no. 164133

    I am experiencing the same problem, but I do not see the set_thermal file in /etc/init.d. I am running FC4 x86_64 on an HP NX6125

    in fact a better cure is to fix the fast problem and this one goes aswell.

    you need to set the no_timer_check=0 at boot time.

    see the forum http://www.linuxquestions.org/questi...5&pagenumber=4

    By the way I also tried updating the BIOS but this didn't help.
    Use this download http://h18007.www1.hp.com/support/fi...oad/22910.html and run it on a Windows machine
    Then create a bootable CD and copy the contents of the floppy created to a bootable DOS CD - see http://www.pavleck.com/modules.php?n...showpage&pid=2 get a DOS prompt to the right location and enter ROMPAQ

    Thanks! The no_time_check=0 boot option really worked. Also the livna.org ATI drivers have my X300 running nicely. Now just need to get the wireless up and running. Anyone had success in that area?
