** Description changed: + [SRU Justification] + + [Impact] + Platforms with Intel Bluetooth AX201 HarrisonPeak (HrP) [8086:06f0] subsystem + [8086:4070] may hang system during suspend if it has ever been paired with BLE + devices. + + [Fix] + Update bluetooth firmware intel/ibt-19-0-4.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, which we SRU-ed intel/ibt-19-0-0.sfi at the + time. This time we've checked the corresponding models refering to blobs in this + REL0318 update, and find intel/ibt-19-0-4.sfi is the only one affected. + + ========== original bug description ========== + This is an follow-up to bug 1850738. In upstream commit c0ca980cee32[1] that we had SRUed once in bug 1850738 contains updates to following files: - * intel/ibt-19-0-0.sfi : already SRUed in bug 1850738. - * intel/ibt-19-0-1.sfi : not affected. - * intel/ibt-19-0-4.sfi : to be SRUed in this bug. - * intel/ibt-19-16-4.sfi : no known reference platform. - * intel/ibt-19-32-0.sfi : not affected. - * intel/ibt-19-32-1.sfi : not affected. + * intel/ibt-19-0-0.sfi : already SRUed in bug 1850738. + * intel/ibt-19-0-1.sfi : not affected. + * intel/ibt-19-0-4.sfi : to be SRUed in this bug. + * intel/ibt-19-16-4.sfi : no known reference platform. + * intel/ibt-19-32-0.sfi : not affected. + * intel/ibt-19-32-1.sfi : not affected.
