Are you all enabling GuC manually? It's not used by default on any currently shipping GPU.
Having them around is harmless though, because while they get loaded (fixing the warning), they are not actually used. -- 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/1939986 Title: Missing firmware files, in Ubuntu 20.04 LTS, for initramfs, when it loads i915 Status in linux-firmware package in Ubuntu: Invalid Status in linux-firmware source package in Focal: Confirmed Bug description: [ Impact ] The i915 driver in Focal HWE kernels (currently 5.11 and 5.13) needs new firmware blobs. Without them, some users reported display/audio issues when installing said kernel. [ Test Case ] 1) Install linux-generic-hwe-20.04 2) echo 'i915' >> /etc/initramfs-tools/modules 3) update-initramfs -u Which leads to multiple warnings: W: Possible missing firmware <foo> for module i915 [Fix ] Add missing firmware blobs from upstream linux-firmware.
