Hi Files seem to have moved from /usr/lib to /lib. https://packages.debian.org/sid/all/firmware-mediatek/filelist https://packages.debian.org/bookworm-backports/all/firmware-mediatek/filelist
>From https://wiki.debian.org/UsrMerge In February 2021, the Technical Committee has resolved that Debian 'bookworm' should support only the merged-usr root filesystem layout, dropping support for the non-merged-usr layout. (978636 <https://bugs.debian.org/978636>) Could this be an issue? Do you have a lib -> usr/lib symlink? How/where does the kernel locate firmware?
