Public bug reported:
I have a many HP ProBook 450 G1 and HP ProBook 650 G3 with fresh install
of Ubuntu Desktop.
They all have a load average of 1.0 when idle (no graphical session
opened).
vmstat shows idle=0% and waiting=~ 100%
The process which uses most CPU time is iio-sensor-proxy (about 1%) and
it's constantly in D state (uninterruptible sleep).
Manually starting this command shows that the sensor (lis3lv02d on both
products) is constantly sending garbage informations (see attachment).
With iio-sensor-proxy service stopped, the CPU load is ~ 0%
As the service is 'static' and can not be disabled, the only workaround
is to remove the 'iios-sensor-proxy' package.
