Title:
[bionic] high cpu load HP probook iio-sensor-proxy
Status in linux package in Ubuntu:
Confirmed
Bug description:
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 =~ 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.
