From: You-Sheng Yang <vicamo@gmail.com> BugLink: https://bugs.launchpad.net/bugs/1849779 [Impact] On some platform, with Intel 9260 Bluetooth fw ver < REL0472, deep suspend (S3) 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 doesn't seem to apply to all platforms with 9260, as there are other platforms with identical chip and fw version but are immune from this issue. [Fix] This can be fixed with newer (>= REL0472) release of fw blob intel/ibt-18-16-1.sfi: |commit |fw rev|4.15.0-66-generic|series| |------------|------|-----------------|------| |c2d8f1b7f820| 0329| waked up|bionic| |ae90c3bce108| 0386| waked up| | |046d1085b19e| 0420| waked up| disco| |1e8253bbaafb| 0450| waked up| | |7444ca40083a| 0472| ok| | |fe48882708de| 0482| ok| eoan| This patch will SRU 0482 to keep synced with eoan. [Test Case] 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. [Regression Risk] The same process is also verified on Dell Precision 7530 that is also equipped with Intel 9260 Bluetooth. However, although also has linux-firmware 1.173.9 installed (fw REL0329), this platform doesn't have such unsolicited resume problem. With fw upgraded to proposed REL0482, there is no known regression found in the suspend/resume and other functions. Low.
