Hi You-Sheng, Sorry for this very late feedback, I just saw your message a few minutes ago as I was not subscribed to this bug.
I've now tested your backport of the patches and I can confirm that it is indeed working on my machine (Dell Latitude 7275). FYI, I was also pointed out that there is an on-going discussion about suspend failures following these patches, details here: https://bugzilla.kernel.org/show_bug.cgi?id=207629 but I'm not seeing this issue in my case. Cheers, Jérôme ** Bug watch added: Linux Kernel Bug Tracker #207629 https://bugzilla.kernel.org/show_bug.cgi?id=207629 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1823076 Title: System wakes up immediately after suspend if Bluetooth is still enabled Status in bluez package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: After replacing my USB mouse with a BT mouse, I noticed my machine would no longer suspend without immediately waking up. i.e. I suspend and see the light go into the slow fade in and out for one cycle and then goes solid and the display wakes up again. If I disable BT (via blueman applet) suspend works fine. I've fixed this by shutting down the BT service before suspend, and starting it back up on wake, as indicated here: https://askubuntu.com/questions/797590/ubuntu-wakes-up-immediately- after-suspend Perhaps this script should be included in blueZ as suspend issues seem very hard to debug and the immediate wake after suspend could be caused many any number of things.
