Notes

mdeslaur

This was fixed in the rpi firmware release 1.2-4+rpt8 included in the 4-0ubuntu1 Ubuntu package. This is fixed in 6-0ubuntu0~20.04.1 in focal-updates, and 4-0ubuntu0~18.04.1 in bionic-updates, but are not in the -security pocket. The affected firmware files don't appear to be in the bluez-firmware package at all.
