Bug Description
System, with Intel 9260 Bluetooth fw ver < REL0472, 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. Known affected fw versions are:
|commit|fw rev/kernel|
|-|-|-|-|
|c2d8f1b7f820|
|ae90c3bce108|
|046d1085b19e|
|1e8253bbaafb|
|7444ca40083a|
|fe48882708de|
This doesn't seem to apply to all platform with 9260, as there are some platforms with identical chip and fw version but are immune from this issue.
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.
