dbus-sensors issue

[Jeff9 Chan(陳松儉_ASRockRack)]

Hi all,
It appears that IO wait is very high all the time. This can be viewed by running `top`. It was traced down to dbus-sensors systemd units. When the units are running, IO wait is >90%. This can impact system performance and also impacts CPU utilization telemetry, since the idle task never runs, which normally means CPU is being completely utilized.

My platform uses below services, stop them will free the IO usage, any idea?

xyz.openbmc_project.hwmontempsensor.service
xyz.openbmc_project.fansensor.service
xyz.openbmc_project.adcsensor.service
xyz.openbmc_project.psusensor.service


best regards

Jeff Chan
