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 = 0x62


This patch looks to be a suspect: 34ff4dbccccce54c83b1234d39b7ad9e548a75dd,
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
   2583
   2680

Thanks
Alan
