I have also not found any affected system but im sure that the microcode=20
links are
recreatad by the last commit of core138.

https://git.ipfire.org/?p=3Dipfire-2.x.git;a=3Dcommitdiff;h=3D699381b6993b942=
8e99a0055dae03e7a222ea9f9

Sometimes git cherry-pick does not the inteded thing if a patch was=20
renamed.
