--- Comment #19 from Raghuram Hegde (raghuram.hegde@intel.com) ---
Thanks for the sharing complete btmon logs.
As evident from the below log snippet, once the remote device is disconnected,
the host will start a Passive scan. The filter policy is set to "Accept all
advertisement" as the previously paired device in the White List (Designer
Mouse) has random address:

Since, passive scan is going on when the system is put to suspend, the system
wakes up when any Advertisement report is received.
Thanks,
Raghu
