Background:
Filed a bug report as per question:
https://answers.launchpad.net/ubuntu/+question/662421
I'm trying to run lm_sensors on my brand new motherboard (Gigabyte
Technology Co., Ltd. Z370 AORUS Ultra Gaming-CF) using the Z370
chipset, and according to the author/maintainer of lm_sensors/it87
driver, fan controls would be supported by chip it8686.
Currently such chip is supported only in it87 version
https://github.com/groeck/it87; unfortunately both Ubuntu's new LTS
Bionic and Torvalds' repositories have got an outdated version of this
driver (and possible lm_sensors itself):
*
http://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/tree/drivers/hwmon/it87.c
* https://github.com/torvalds/linux/blob/master/drivers/hwmon/it87.c
Can you please update Bionic (at least) to feature this updated driver?
Controlling fans speed and other motherboard parameters would be great,
especially on new hardware.
Thanks!
