Hi.

I'm using 3.17.0-rc3-00002-g7505cea kernel on Dell XPS 15 machine:
DMI: Dell Inc. XPS 15 9530/XPS 15 9530, BIOS A06 07/16/2014 (this is latest bios)

After loading thermal acpi driver I get:

[54136.633643] ACPI: Invalid active2 threshold
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[54136.633761] thermal LNXTHERM:00: registered as thermal_zone6
[54136.633763] ACPI: Thermal Zone [TZ00] (28 C)
[54136.634009] thermal LNXTHERM:01: registered as thermal_zone7
[54136.634011] ACPI: Thermal Zone [TZ01] (-266 C)

I assume bios is buggy (right?)

What problems can happen to this machine due to this problem? It is quite hot frequently, so I wonder if there is some thermal management problem with it.

Thanks,

Well, we don't seem to like the value for some reason. Also the -266 C for TZ01 looks suspicious.

I'm leaving this question to Rui.

It looks like ACPI thermal driver fails to parse _AC2 control methods. please attach the acpidump output.

this is a BIOS bug. _AC2 is defined while _AL2 is not, thus this is an invalid active trip point.
But it won't hurt IMO, because there are two ACPI Fan devices, and they are both used (for active trip point 0 and 1) in the ACPI thermal management in your laptop.

This is more serious to me.

Q: vger.kernel.org postmasters - always rude and impolite, hmm?
