Test the kernel of comment#5 with Dell XPS 13 9360 (CID 201606-22338): - The kernel fixes the issue. It could not reproduce the issue. - No regression was found.
The result is here https://certification.canonical.com/hardware/201606-22338/submission/128887/ Still waiting for the other test reports on the other platforms. -- 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/1759821 Title: Dell XPS 13 9360 bluetooth scan can not detect any device Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: == 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.
