X2200 powernow problem with RHEL 5

Discussion in 'Sun Hardware' started by Richard Skelton, Aug 4, 2008.

  1. Hi,
    I am trying to use powenow on a X2200 running RHEL 5.
    I have enabled it in the BIOS but I see in dmesg :-
    powernow-k8: Pre-initialization of ACPI failed
    powernow-k8: Found 2 Dual-Core AMD Opteron(tm) Processor 2222 processors
    (4 cpu cores) (version 2.20.00)
    powernow-k8: Your BIOS does not provide _PSS objects. PowerNow! does
    not work on SMP systems without _PSS objects. Complain to your BIOS vendor.

    The curent BIOSVersion = S39_3B25
