Most recent kernel where this bug did not occur: n/a Distribution: n/a Hardware Environment: Samsung X65 (x86_64) Software Environment: ?? Problem Description: On my Samsung X65 notebook (Intel PM965 + ICH8M, Core 2 DUo), almost all ACPI modules lead to a complete freeze of the machine, leaving no error messages. I blacklisted the modules ac battery button fan processor thermal. Only basic ACPI support gets loaded upon system boot. modprobe fan works fine - the module gets loaded, no freeze. All other modules freeze the system. I extracted and recompiled DSDT, but encountered no errors and no warnings. I will attach several debugging outputs. I reproduced this with several kernels, vanilla 2.6.23.1, vanilla 2.6.22, 2.6.22-ubuntu, and without the nvidia binary module - it makes no difference. Steps to reproduce: Load any ACPI sub-module, like: modprobe processor

Another addition: ACPI events such as closig the laptop lid ot hitting Fn+VolumeUp also lead to complete freeze.
Another addition: I chose component: "power-processor" arbitrarily, in fact it applies to ac, battery, button, processor, and thermal as well. The only exception being fan, which loads fine. Feel free to move this bug to a more appropriate component category.
