I don't think you need a patch. Enable iio-sensor-proxy again. You probably want to change hysteresis. This will decide how much change in sample data before data is sent to user. OR need to reduce sampling frequency.
Most probably this is accel_3d, which in your case /sys/bus/iio/devices/iio:device3. Recheck with the "name" attribute. Try adjusting in_accel_hysteresis to some higher value and read back if this is accepted by the sensor. For example #echo 0.000010 > in_accel_hysteresis Also try to reduce in_accel_sampling_frequency. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1719795 Title: Dell 7140 avarage power consumption in idle increased by 1.3-1.5 times due to events by INT3432 Status in Linux: Invalid Status in linux package in Ubuntu: New Bug description: On Dell Venue 11 Pro 7140 average power consumption in idle increased by 1.3-1.5 times due to events coming from INT343A. According to powertop since Linux 4.10 INT3432:00 generate around two hundred events on average, in /sys/devices/pci0000:00/INT3432:00/i2c-6 there is two devices: INT343A and SMO91D0. AFAIK INT343A is rt286. With Linux 4.9.0-4.9.45, Linux 4.11.0-4.11.12 in idle there is around 100 wakeups per second in sum, battery discharge rate around 3-3.5 Watts per second. But with Linux 4.9.46-4.9.51, Linux 4.10.0-4.10.17, Linux 4.12.0rc1-4.13.3 - around 300 wakeups per second on average, due to events coming from INT3432:00. With Linux 4.13.3 battery discharge rate around 4.5 Watts per second. Probably some commit was backported to Linux 4.9 between .45 and .46 releases. I have no idea why issue is not reproducible on any Linux 4.11 release I tried. Sometimes INT3432 events rate fall from two hundred to one hundred for shorts period of time (for example I observe this right now on Linux 4.10.0 while removing/installing packages). Message like this sometimes appear in dmesg: [ 731.226730] i2c_hid i2c-SMO91D0:00: i2c_hid_get_input: incomplete report (53/13568) Complete dmesg with Linux 4.13.3 is attached.
