F14 - kacpid using 100% CPU on one core

Found this solution over at our brothers from Ubuntu.
Works fine under F14

System :

Compaq 6710b laptop

Code:

uname -a 
Linux klaptop2 2.6.35.9-64.fc14.i686 #1 SMP Fri Dec 3 12:35:42 UTC 2010 i686 i686 i386 GNU/Linux

Problem: One core is used nearly 100% by kacpid as shown by <top>

Solution:
add

Code:

  echo disable > /sys/firmware/acpi/interrupts/gpe01

Code:

/etc/rc.local

After reboot kacpid is gone from the list in <top>
