Title:
load >= 1 while idle for no obvious reason with ACPI
Status in linux package in Ubuntu:
Confirmed
Bug description:
My idling server will stay at load >=1 if ACPI is active, for no
obvious reason.
Adding "acpi=off" to grub will resolve this and load falls to 0.0x as
expected.
But I use the power button to tell the box to shut down and without
ACPI, systemd cannot respond to the power button's ACPI event.
My server is an Acer Easystore H340, that's a small NAS box with four
disk bays and an Atom 230 in it. That's standard x86 hardware capable
of running x86_64 kernels.
Recently, it was upgraded from 14.10 to 15.04 x86_64. Only after that
upgrade did I notice the load >= 1 problem, although it may have been
there in previous releases, already.
No idea how to debug this.
To resolve this, I either need
- a way to fix load >= 1 with ACPI
or
- a way to respond to the power button without ACPI
Thanks.
