[Bug 56246] Re: kacpid-work eat 99% CPU after resuming from hibernate

[Diogo]

In my case I only have one kacpid process.
I used various Ubuntu releases and since DAPPER I have this problem. I've tested EDGY, FEISTY, and all the kernels used in those releases.
As I known kacpid is a communication process between acpi and kernel, in fact this bug usually starts when I connect or disconnect the battery.
The CPU goes to 75-80-85...-90-95% and there is nothing running.
The pc over heats and the fan doesn't start...When I reboot the pc, the bios launch the fan, and it starts working in Ubuntu.
I've tested fedora core 6 and the bug is there too, but it allows you to run a console and launch top, in Ubuntu the only thing I can do is a simulation of power down (poweroff in the button :P).

I don't know where the bug is but it's there....I've noticed that many
people have this problem, but they do not report, so I think that it is
important to refer it one more time, and if you google around you'll
find more people with it.

I' using an Asus Notebook, and I've noticed that this happens in most of
the cases in notebooks.
