Device: XPS 13 7390 Image: 19.10 Beta Kernel: updated to 5.3.0-13-generic (from 5.3.0-10-generic)
With kernel 5.3.0-10-generic, the device wouldn't suspend properly when a BT device was connected to it. After updating to 5.3.0-13-generic, the issue is gone. I can use a BT mouse, then suspend the device (by pressing the top-right menu, holding Alt key and clicking the "pause" button), and the device will indeed suspend and only resume when I press a key on the keyboard or the power button. -- 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/1844247 Title: BT advertising packet wakes up the system from S3 and suspend-to-idle Status in HWE Next: New Status in linux package in Ubuntu: Fix Committed Status in linux source package in Bionic: Fix Committed Status in linux-oem source package in Bionic: New Status in linux source package in Disco: Fix Committed Status in linux-oem source package in Disco: New Status in linux source package in Eoan: Fix Committed Status in linux-oem source package in Eoan: New Status in linux source package in FF-Series: Fix Committed Status in linux-oem source package in FF-Series: New Bug description: [Impact] The new feature added by below commit let BT device to wake up the system from S3 or s2idle. a0085f2510e8 ("Bluetooth: btusb: driver to enable the usb-wakeup feature") But this feature also wakes up the system randomly from an unpaired BLE device by its advertising packets. [Fix] There is no easy way to fix this and requires firmware update, so current solution for this is to revert it. 1ffdb51f28e8 ("Revert "Bluetooth: btusb: driver to enable the usb-wakeup feature"") [Test] Verified on machines which has paired BLE devices, and can't be waken up by BT devices after entered suspended. [Regression] Yes, it reverts the feature by waking up system from s2idle by paired BT devices, but this feature introduces regression, so I'd suggest to revert it.
