Just realized right now, if you are using Arch, the firmware seems to be packed
in a xz archive on my system. It was still working here because for some reason
the .bin probably is getting loaded before the .bin.xz file from the
distribution.

By the way, I've seen that a Realtek engineer has updated the firmware file at
the end of last year, as of
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/rtl_bt/rtl8761bu_fw.bin?id=45dc5f0b8e2f2d43312d22511cb26658b9ee2c80,
but the bug with that firmware still remains. I need to force disable and
enable the device.

I'll probably just get an adapter for a mPCIEx or M2 laptop to PCIEx and
install an already available Intel module that I got flotaing around at this
point, I doubt that this will ever be fixed on this hardware, unfortunately.

Marco.
