Bluetooth works fine in Windows. The first dmesg line seems interesting: usb
4-2.2: Product: Bluetooth Radio  but somehow there's no bluetooth showing up in
lsusb

dmesg with bluetooth

Update: I have extracted Lenovo's RTL8822BE wifi and bluetooth firmware from
their Windows driver packages and gotten the bluetooth partially working. It
works if the system is up to sleep and then woken up again, though it doesn't
work when the system is booted up for the first time.

lsusb info:
Bus 004 Device 008: ID 0bda:b023 Realtek Semiconductor Corp.

I am hosting the firmware here https://github.com/samcv/A485-RTL8822BE-firmware
which has detail about how I extracted the firmware so I will only repost
relevant info here.

So there is still an issue loading firmware at boot, which hopefully  makes
this issue easier to solve.

Here is new dmesg | grep -Ei 'blue|8822|rtlwifi' output (full log is attached)

Closing this. It has been fixed as of BIOS version 1.06 from Lenovo.
