[Bug 496937] Re: Jaunty: kacpid running at 70% of CPU Time on Pentium 4

[Its Me]

Have you recently installed any new hardware on the laptop?  Maybe changed
the BIOS settings?   The reason I ask, is the issue I was having went away
when I installed some new hardware (sound card, in my case).  Can't explain
it, but it did.  Also, in my case kacpid was only going up high for one of 2
CPU's.
