Xenial SRU request submitted:
https://lists.ubuntu.com/archives/kernel-team/2018-March/091275.html
** Description changed:
+ == SRU Justification ==
+ This bug currently exists in the 4.4.0-118 -proposed kernel. Due to this
+ bug, a Dell XPS 13 9360 bluetooth scan can not detect any devices.
+
+ This regression was caused by mainline commit fd865802c6. This commit was
reverted
+ in mainline by the requested commit, 7d06d5895c15. This commit was already
+ reverted in upstream stable 4.4.116 by commit: 356c942. However, Xenial
-proposed only
+ has up to the 4.4.114 stable updates. This regression has been in the 4.4
kernel
+ since 4.4.110(Ubuntu 4.4.0-117).
+
+
+ == Fix ==
+ 7d06d5895c15 ("Revert "Bluetooth: btusb: fix QCA Rome suspend/resume"")
+
+ == Regression Potential ==
+ Low. This revert was also cc'd to upstream stable and is in the upstream
4.4.y
+ kernel. This revert should happen to prevent a regression from moving to
-updates
+ from -proposed.
+
+ == Test Case ==
+ A test kernel was built with this patch and tested by the original bug
reporter.
+ The bug reporter states the test kernel resolved the bug.
