On latest git, powertop shows 20 ACPI interrupts per second.
Previously, this was closer to 1 per second. See attached output (a
vs b, "a" is from 2.6.29-rc8).
This is from a pretty sparse KDE desktop. Normally I run
gnome-power-manager, but I killed it to make sure that wasn't causing
any problems.
gpe18: 60975 enabled
gpe_all: 60975
sci: 60975
which I presume means lots of EC interrupts.
[ 0.134068] ACPI: EC: GPE = 0x18, I/O: command/status = 0x66, data

This patch looks to be a suspect:

Please check if reversing it helps
No, I still get 20 ACPI interrupts per second.
I tried without powertop, just in case that was provoking it, but it
still happens:
alan@alan-eeepc:/sys/firmware/acpi/interrupts$ cat sci; sleep 5; cat sci

Thanks
