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
with a home-compiled version of the 2.6.30.1 source release. I have the latest
acpi packages from debian, and it was happening with slightly older kernels
too.
