This is almost certainly the same issue that was mentioned in this thread: http://www.spinics.net/lists/linux-acpi/msg40404.html I can confirm it worked on vanilla 3.6.8 and debian 3.2 kernels. It doesn't work on 3.7 or 3.8-rc kernels. If I should provide any new information not present in the mentioned thread (or repost it), please tell me to do so. Thanks, Adrian
