Reassigned to ACPI.

Comment 2 ykzhao 2009-12-22 01:13:55 UTC

Hi, Victor
    Will you please attach the output of acpidump?
    Please also attach the following output:
      > cat /sys/firmware/acpi/tables/dynamic/SSDT1 >ssdt1
      > cat /sys/firmware/acpi/tables/dynamic/SSDT2 >ssdt2
  
    Please boot the system with the boot option of "cpufreq.debug=0x07" and attach the output of dmesg.

Thanks.

Comment 5 Victor 2009-12-22 07:50:31 UTC

an't make

cat /sys/firmware/acpi/tables/dynamic/SSDT1 > ssdt1

because directory

/sys/firmware/acpi/tables/dynamic/

is empty.

Hi, Victor
    I check the acpidump and find that there is no _PSS object in ACPI table, which is required by acpi_cpufreq driver.
    So IMO this is a bios bug. Will you please try to check whether the updated bios is available and see whether it can be fixed.

Thanks.

As this is a BIOS bug, this bug will be rejected as Documented.

Thanks.
