Bug Description
[Impact]
To whom it may concern:
I was experiencing frequent wake-ups from s0i3x on a HP Pro 435 G9 convertible [1] using the Qualcomm FastConnect 6900 Soc [2]. The issue is related to FW revision WLAN.HSP.
It appears the SoC increasingly triggering wake-ups after being suspended for approx. 4 hrs.
Read the full story at [4].
The solution is to upgrade SoC firmware to rev WLAN.HSP.

[Fix]
Upgrade firmware, as mentioned above.
[Test case]
Verify WiFi functionality on WCN6855 works and that unplugging power cord during suspend doesn't wake system.
[Where Problems might occur]
It's firmware, what could possibly go wrong? If so, connectivity issues wit ath11k based NICs.

Just a little extra context for this.
Some systems this manifests as described because they don't use _BTP for notifying when battery has crossed a critical threshold but instead notify the OS of every battery level change.
Systems that use _BTP still will have the issue manifest with other ACPI events that shouldn't wake the system such as unplugging power adapter or closing lid.
Although you reported this on Kinetic it affects all the supported Ubuntu releases. I've added tasks for the others as well.
