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? Mark Russell ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
