Bug description:
[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 ==========
