BugLink: https://bugs.launchpad.net/bugs/1862734 [Impact] Platforms with Intel Bluetooth AX201 HarrisonPeak (HrP) [8086:02f0] subsystem [8086:4034] may hang system during suspend if it has ever been paired with BLE devices. [Fix] Update bluetooth firmware intel/ibt-19-0-1.sfi to REL0318 or newer. [Test Case] 1. pair with BLE devices. They doesn't have to stay connected/powered on during the test. 2. make sure Bluetooth is now receiving LE ADV broadcats, which should leave messages in dmesg like: Bluetooth: hci0: advertising data len corrected 3. suspend the system a few times to see if SUT is still resumed unexpectedly within a short period (< 1 minute). [Regression Risk] Low. This change only updates firmware blob for the specific hardware affected. [Other Info] Same case in a resolved bug 1850738, bug 1858776, which we SRU-ed intel/ibt-19-0-0.sfi, intel/ibt-19-0-4.sfi respectively. With new platforms enabled, intel/ibt-19-0-1.sfi is found to suffer the same symptom and is being upgraded separatedly.
