Subject: ACPI CPU Usage problems ( events process taking near 100% )
Date: Fri, 2 Jan 2004 20:20:42 -0700 (GMT-07:00) [thread overview]
Message-ID: <27441069.1073100042475.JavaMail.root@thecount.psp.pas.earthlink.net> (raw)
I have search google and scanned the mailing list archive and have not yet found the solution for this.
Here is my case. I have a Toshiba Satellite Pro 6000 laptop. I just freshly loaded Gentoo linux on the machine. It has previously been loaded and run with Libranet without any problems. I am currently using the new 2.6 kernel.
Whenever ACPI support is enabled I end up with a process 'events/0' that takes near 100% of the cpu, as well as the cpu fan going crazy (ie comes on full speed and doesn't stop till I turn the notebook off). I have disabled all ACPI options except the basic support and that makes no difference. I have disabled APIC support (don't know that it makes a diff). I have also disabled cpu frequency scaling just to make sure. If I completely remove ACPI support from the kernel, or turn it off on boot, then that problem goes away, though turning it off causes other issues. So I know the problem revolves around ACPI but I can't figure out how to fix it.
I have also tried using the mm sources which includes the latest version (20031203) of the ACPI stuff, to no avail. I also ran across a thread that indicated I should try to comment out some code in the evrgnini.c file, but that also didn't do anything.
I have verified that I'm running the latest bios version as well. I have also searched google to see if there was a dsdt available for my notebook and I haven't found anything.
Anyone know how to fix this?
