acpi_tz0: error fetching current temperature

[Sascha Wildner <saw@xxxxxxxxx>]

Hi all,

I'm getting lots of ACPI messages on a new installation of DFly:

May 10 17:53:16 unack /kernel: ACPI-1288: *** Error: Method execution 
failed [\RTMP] (Node 0xc0cb2218), AE_AML_UNINITIALIZED_LOCAL
May 10 17:53:17 unack /kernel: ACPI-1288: *** Error: Method execution 
failed [\_TZ_.THRM._TMP] (Node 0xc0cb23e0), AE_AML_UNINITIALIZED_LOCAL
May 10 17:53:17 unack /kernel: acpi_tz0: error fetching current 
temperature -- AE_AML_UNINITIALIZED_LOCAL

I have "device acpica5" in my kernel config. I'm wondering whether it's 
a hardware or a software problem. ACPI initializes as follows during boot:

acpi0: <GBT    AWRDACPI> on motherboard
installed MI handler for int 9
acpi_bus_number: root bus has no _BBN, assuming 0
AcpiOsDerivePciId: bus 0 dev 7 func 0
acpi0: power button is handled as a fixed feature programming model.
acpi_cpu0: <CPU> on acpi0
acpi_tz0: <thermal zone> on acpi0
acpi_button0: <Power Button> on acpi0

The BIOS shows a CPU temperature of 29 degree C (which seems a bit low 
for a machine running 24h for a couple of days now). The temperature 
seems to be changing sometimes, so I think it's an actual measurement. 
I'm not sure about the BIOS options, though. I've enabled Power 
Management and set PM Control by APM to No.

What is wrong here?

Regards,
Sascha
