Hi. I have a system with Intel D945GCLF2 motherboard with Atom CPU. I found that when I enable auto speed regulation of case fan. FreeBSD will have a process "acpi_task_0" which consume all resource of one of the core of the CPU. The fan seems fail to change RPM itself. Is there any solution to this problem without disabling the auto speed regulation?
