Description Anthony Tuel 2008-02-03 16:36:07 UTC
After applying the latest kernel update to 2.6.22.16-0.1 on my thinkpad z61p, my CPU is now locked into full speed.  The gnome cpu frequency applet prints a warning on startup indicating that cpu scaling is not available.

ACPI seems to detect multiple power states during boot but also report some errors:

<4>ACPI Error (dsopcode-0250): No pointer back to NS node in buffer obj ffff8100bc62c1a0 [20070126]
<4>ACPI Error (psparse-0537): Method parse/execution failed [\_PR_.CPU0._PDC] (Node ffff810037fc1230), AE_AML_INTERNAL
<6>ACPI: CPU0 (power states: C1[C1] C2[C2] C3[C3])
<6>ACPI: Processor [CPU0] (supports 8 throttling states)
<4>ACPI Error (dsopcode-0250): No pointer back to NS node in buffer obj ffff8100bc9d3ee0 [20070126]
<4>ACPI Error (psparse-0537): Method parse/execution failed [\_PR_.CPU1._PDC] (Node ffff810037fc1fb0), AE_AML_INTERNAL
<6>ACPI: CPU1 (power states: C1[C1] C2[C2] C3[C3])
<6>ACPI: Processor [CPU1] (supports 8 throttling states)
<6>ACPI: Thermal Zone [THM0] (38 C)
<6>ACPI: Thermal Zone [THM1] (39 C)



powersave reports this on startup:
