Gkrellm reports 100% CPU load, and so does top. "ps aux" shows nothing unusual. After experimenting with various compile options, I believe it has something to do with the main kernel configuration variable CONFIG_ACPI. I haven't yet narrowed it down to a specific source code module. Reproducible: Always Steps to Reproduce: Assumed: Toshiba Satellite laptop with a working base system e.g. compiler, bash, etc. GRUB bootloader. Every step listed (even those that should be obvious). 1. emerge either =gentoo-sources-2.4.20-r1 or >acpi-sources-2.4.20-r6 2. cd /usr/src/ 3. set "/usr/src/linux" symlink accordingly 4. cd /usr/src/linux 5. make menuconfig 6. under General Setup, say yes to "PCI support" 7. under General Setup->ACPI Support, say yes to "ACPI support" 8. other configuration options seem to be inconsequential, configure kernel so that it will boot. 9. make dep && make clean bzImage modules modules_install 10. mount /boot # if necessary 11. mv arch/i386/boot/bzImage /boot/bzImage 12. reboot # boot new kernel 13. log in # should happen under any user id 14. run top 15. note system CPU usage and process processor times Actual Results: Noted that top displayed statistics such as (but not exactly): load average: 1.60, 0.96, 0.76 CPU states: 0.0% user,100.0% system, 0.0% nice, 0.0% iowait, 0.0% idle No processes displayed anything other than 0.0 under the %CPU column. Expected Results: Top should display something more along the lines of (at this point): load average: 0.00, 0.00, 0.00 CPU states: 0.0% user, 0.0% system, 0.0% nice, 0.0% iowait,100.0% idle No processes displaying anything other than 0.0 under the %CPU column. system specs: Toshiba Satellite 5005-S504 specs listed in included .pdf file.

from the gkrellm FAQ: Linux Kernel 2.4.x: heavy CPU usage The kapm-idled process records heavy CPU usage when the system should otherwise be quiet. Recompile your kernel with kapm-idled disabled to get rid of this annoyance. I assume that acpi does something similar.
yep, but if you want a cooler cpu.. idles are nice. you can make gkrellm only report user process loads also.. helps. not a kernel bug though.
