I am getting the same warning messages with the fully-updated 20.04. <snipp>
W: Possible missing firmware /lib/firmware/amdgpu/arcturus_smc.bin for module am dgpu ryzen@cp7:~$ apt policy linux-firmware linux-firmware: Installed: 1.187 Candidate: 1.187 Version table: *** 1.187 500 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://us.archive.ubuntu.com/ubuntu focal/main i386 Packages 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1850654 Title: update-initramfs complains of missing amdgpu firmware files Status in linux package in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: Fix Released Status in linux source package in Bionic: Invalid Status in linux-firmware source package in Bionic: Fix Released Status in linux source package in Eoan: Confirmed Status in linux-firmware source package in Eoan: Fix Released Bug description: SRU Justification Impact: With 5.3 update-initramfs reports several missing amdgpu firmware files: update-initramfs: Generating /boot/initrd.img-5.3.0-19-generic W: Possible missing firmware /lib/firmware/amdgpu/vega20_ta.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/raven_kicker_rlc.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/navi10_mes.bin for module amdgpu Of these, only raven_kicker_rlc.bin has been added to upstream linux- firmware. Fix: Add raven_kicker_rlc.bin to linux firmware, and remove the other files from modinfo for amdgpu. Test Case: Once fixed, the warnings from update-initramfs should be gone. Regression Potential: Adding a missing firmware is unlikely to break any working hardware. Removing the other missing files from modinfo will not cause regressions either, however if the firmware is added later update-initramfs will not add the files to the initramfs until the firmware is added back to modinfo.
