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

[Its Me]

sorry to hear kacpid is still giving you trouble.  My case went away after I
installed a high end sound card. Not sure why but it did.

Some of the comments I got from the guru's at Ubuntu, was to try liveCD of
the last version of Ubuntu. It did not help in my case.

Have you tried modifing the kernel parameters related to ACPI at boot time?
I tried the following ones with results indicacted:
  ACPI=OFF  solves the problem of CPU Time (of course as theirs no ACPI
running).
  ACPI=HT  works as well, though I loose "dual processor" feature.
