is /dev/bus/iio even properly populated? See LP: #1807250 LP: #1804804 LP: #1792813

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. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: gdm 1371 F.... pulseaudio ljanvier 2104 F.... pulseaudio /dev/snd/controlC0: gdm 1371 F.... pulseaudio ljanvier 2104 F.... pulseaudio DistroRelease: Ubuntu 18.04 MachineType: Hewlett-Packard HP ProBook 650 G1 Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=fr_FR.UTF-8 SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-23-generic root=UUID=e375b9cb-3776-455a-bb2e-24f826528047 ro quiet splash vt.handoff=1 ProcVersionSignature: Ubuntu 4.15.0-23.25-generic 4.15.18 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
