Summary: _PR namespace not initialised on HP Pavilion dm1 with
Intel Celeron SU2300
Product: ACPI
Version: 2.5
Kernel Version: 2.6.33
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ACPICA-Core
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
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.
