Public bug reported: Similar to bug 1849779, on systems with Intel 9560 Bluetooth fw ver REL0450, deep suspend will be interrupted and resume automatically once it has been paired with a BLE device. The device doesn't have to remain connected, as long as there are BLE devices near by broadcasting LE ADV.
This can be fixed by updating intel/ibt-17-16-1.sfi from upstream commit https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=b6427bf4faae9b8864e303d88c3ec8d0df017dac. Steps to reproduce: 1. pair with BLE device and turn off the device. It should be listed as Disconnected in System Bluetooth settings. Close the settings app as well. 2. run `sudo btmon -t` in the background, make sure LE ADV packets pop up. 3. run `sudo btmon -t` on another host to make sure there are LE ADV packets during the suspend period. 3. trigger system deep suspend (S3) on DUT. 4. wait for around 1 minutes (depending on the surrounding environment) and see if the DUT is resumed unsolicitedly. Expects: DUT only resumes when power button pressed or on other explicit requests. Actual: DUT resumes unsolicitedly within 1 minutes. ** Affects: linux-firmware (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857673 Title: System will auto resume from sleep on receiving LE ADV after paired with BT LE devices (Intel 9560 HrP) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1857673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
