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.
