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.
