    Default OpenSuse 11.1 and Multiple Processors

    Hi All,

    A fresh load of OpenSuse 11.1 is performing poorly on an Intel OR840 with two PIII (1 GHz).

    The hardware info applet only shows the first CPU (Processor 0). I have a handful of log messages, but I don't know how to correct them.

    Reading is kind of slim when searching OpenSuse for similar issues (one past post regarding 10.3). Any ideas?

    Thanks,

    Jeff

    Try adding as it suggests: CPUFREQ=no
    To the boot arguments

    When you boot, pause the timer by moving the down arrow, move it back to default boot and type: CPUFREQ=no
    The text should appear a little lower down where you may see already: vga...

    Sorry, then hit enter, obviously.

    Failsafe boot - did you try that?

    Hi caf4926,

    >> Try adding as it suggests: CPUFREQ=no
    No joy with a standard boot, but I suspect I have X problems.

    Thanks.

    > Failsafe boot - did you try that?
    That's what I've been booting for the most part (excruciatingly painful).

    I found changing the 'cpumax=0' to 'cpumax=2' brought performance up where I expected it.

    The problem is not the performance itself, but the number of processors linux use. For checking that all is OK you may look to /proc/cpuinfo where 2 CPUs must be presented.
