Don't know if that can help but i moved to 5.8.1 kernel . It works well with my
previous workaround :
remove ibt- * from /lib/firmware/intel then copy all ibt-* from
linux-firmware_1.183.2_all.deb
It works fine until an apt-upgrade installs the new latest linux-
firmware 1.187.3 .
This time i do the first step again but nothing work . So i reinstalled
linux-firmware 1.187.3 and i deleted all ibt-12* then update-initramfs -u -k
`uname -r` .
It works now, until the next update i suppose.
This time no firmware it loaded at boot for bluetooth
