And there were no changes to the code from v3.0 to v3.1.1. So, it is either a bug in something else, a problematic interaction of the driver with something else, or a latent thinkpad-acpi bug that some change elsewhere has exposed. Are the events reported by acpi_listen from arch-linux exactly the same in v3.0.9 and v3.1.1 ? I know some events are missing in your v3.1.1, but I am interested in the ones that do get reported. Although you really should be using the input device for the hotkeys, and not any of the 0x10xx events. Those are driver-specific and deprecated, it is all explained in Documentation/laptops/thinkpad-acpi.txt. So, it really might mean that you have something in userspace reading that input device and synthesizing the ACPI HKEY events thinkpad-acpi deprecated for a long time now. I know some distros did that instead of switching to an input-device-based hotkey daemon. Please check for that possibility, that daemon could be the one having problems with 3.1.1... -- "One disk to rule them all, One disk to find them.
