This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The sensor stops working (and reports stale values) after the system resumes from suspend-to-ram/suspend-to-disk PM states. == Fix == AV_CONF register (RH & TEMP. oversampling ratio's) and CTRL1 register (ODR & BDU settings) values are lost after suspend. While the change in AV_CONF updates the sensor resolution modes (overriding the user configuration before the device went to suspend); loss of the contents of the CTRL1 register leads to failure in reading sensor This patch restores the AV_CONF & CTRL1 registers after Already submitted upstream for both 4.17.y and 4.14.y (LTS) for review: 4.17.y: https://marc.info/?t=152455871600007&r=1&w=2 4.14.y: https://marc.info/?t=152506242000001&r=1&w=2 However, the issue is only affecting the Dell GW and not ST micro devel. boards. == Risk of Regression == Low.Tthe bug affects only the Dell GW and the patch is being carried in linux-oem (4.15.y) since last 2 years without any regression. linux-oem buglink: https://bugs.launchpad.net/bugs/1769658 This bug is for tracking purposes only, please don't triage.
