Description Elio Voci 2010-04-17 07:10:50 UTC
System reports at boot:
[    1.330173] ACPI Error (psargs-0359): [\_PR_.CPU0._PPC] Namespace lookup failure, AE_NOT_FOUND
[    1.330186] ACPI Error (psparse-0537): Method parse/execution failed [\CPUL] (Node f6c15ae0), AE_NOT_FOUND
[    1.330243] ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.TZ01.OTHD] (Node f6c15918), AE_NOT_FOUND
[    1.330303] ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.TZ01._TMP] (Node f6c15870), AE_NOT_FOUND

I've disassembled DSDT but nothing seems evidently wrong.
Problem appears with kernels 2.6.26, 2.6.30, 2.6.32, 2.6.33 (currently in use)
I've enabled ACPI debug and noticed that "Initialisation of Region [_PR_]" is not reported.

Obviously, processor is not recognised and all services depending on it fail (power, speedstep, etc.)

Firmware is F.13 (25/01/2010), the latest available from HP.

Any hint on what to address the attention is welcome.
