I really do not know if the problem was definitively solved. Because Bluetooth
devices now appear in GNOME.

It is still affecting me on vanilla 4.20 and 4.19.12.
I was able to modify drivers/bluetooth/btrtl.c to use rtl_bt/rtl8821c_fw.bin
firmware for this device.

Add IC_INFO(a99e, 826c) to load rtl8821c firmware
With this patch, it has been working fine for a week using Bluetooth mouse.
Other things tested:
- File transfer
- A2DP Source

vasthusya,
I also see this issue, but this only happens to reboot.
Do you see this on cold boot?

Kernel messages from various boot states.
Yes, the coldboot lmp_subver=8221 & hci_rev=c are correct and Bluetooth works
on vanilla kernel.
Unfortunately, I must restart the computer in order to gain CPU clock boost on
my Ryzen 5 2500u.
Separate issue, haven't checked around here for that bug yet.

0004-Bluetooth-btrtl-Expose-btrtl_device_info.patch
Hi Kai,
Your patch #2 had two issues:
- btrtl_device_info definition is unavailable in hci_h5.c as it's not in
header
- a couple of argument type mismatch
It would have compiled fine when you don't have CONFIG_BT_HCIUART_RTL=y
I have made it compilable and running it now with working Bluetooth.
Thanks
