Bug#536240: linux-image-2.6.30-1-686: kacpid & kacpi_notify use CPU cycles when lid closed on Acer Aspire One

[Джонатан Вашингтон <dzhonw@mail.ru>]

Package: linux-image-2.6.30-1-686
Version: 2.6.30-1
Severity: normal

When the lid is closed on my Acer Aspire One (D150-1577), kacpid and kacpi_notify both make very active use of the CPU.

I cannot find any evidence of a repeating lid event in my logs as suggested by similar problems had by others.  Also, my DSDT appears to have the relevant clause to prevent this.

This happens with 2.6.29 and 2.6.30 images from debian unstable, as well as my own 2.6.30.1 kernel.  I have the latest acpi packages, and it was happening with slightly older ones too.
