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?
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU
COMMAND

acpi_task_0

idle: cpu0
11 root 1 171 ki31 0K 8K RUN 1 61:20 1.07%
idle: cpu1
Thanks very much.
