Damn, one case I didn't test. To be sure is this after sysupgrade? If yes please revert these commits: 546fced2a23557e95dd34246744c3aa6cad92fe6 x86: add intel microcode entries to grub config 022ffb56b2491fd7d8051ac6e6c7622ecc313d8f intel-microcode: create early load microcode image a822283c7e56bb3b409712e0eb9af5a91aac247d x86: add amd microcode entries to grub config 975019b3a755ec3b91864b60b45e5ee104075096 amd64-microcode: create early load microcode image I'll try to come up with better transition. > > > Regards > -- TMN _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
