Bug description:
[Impact]
Realtek 8821C Bluetooth controller may stop working after S3.
[Fix]
Use the new firmware from Realtek (Release Version: 0xAA6C_A99E)
Link:
https://lore.kernel.org/linux-firmware/[email protected]/
[Test]
With the new firmware, the BT controller works and can pass 1000 cycles
of S3.
[Regression Potential]
This is tested with some BT devices, no regressions found so far.
However, regression could still happen because there are many
Bluetooth peripherals we can't test.
We'll escalate the issue to Realtek if regression ever happens.
