Most recent kernel where this bug did *NOT* occur: I don't know Distribution: Debian GNU/Linux Etch 4.0 Hardware Environment: Laptop HP Pavilion DV4017EA with Intel Celeron M370 1,5Ghz and Intel 915GM chipset Software Environment: KDE and console for desktop only Problem Description: At the kernel boot time, a curious message appears on the screen under the ACPI section, between "thermal zone THR0" and "thermal zone THR1" "ACPI: Invalid passive threshold" Is that a bug? How can I ger rid off this message? Thanks Damien Steps to reproduce: at each boot time

No, this is a warning telling you that only part of the methods that support ACPI passive cooling policy in this thermal zone is offered by the BIOS. This situation is rare as it may be a BIOS bug that conflicts with ACPI spec. Could you please attach the acpidump output so that we can make it clearer? And the output of #cat /proc/acpi/thermal_zone/THR0/* and #cat /proc/acpi/thermal_zone/THR1/* is also helpful. :)

Hello, You will find enclosed the requested files to investigate. Damien
Yes, the problem is quite clear. Thermal_zone device THR1 has _PSL and _PSV methods but the _TC1,_TC2,_TSP are lost, which is unacceptable due to ACPI spec. "ACPI: Invalid passive threshold" is exported by ACPI thermal_zone driver. This is actually an BIOS bug. Update the BIOS may solve this problem. :)
