Package: fio Version: 3.6-1 Since version 3.6 (https://github.com/axboe/fio/commit/a817dc3b3b5a0efc95aaca366875eac67607cd5b ) fio tries to optimize itself for the host it is being built on which can lead to problems if the binary is shared to a machine with a lesser CPU. Red Hat avoid this issue by disabling fio's optimization CFLAGS and explicitly passing their own via EXTFLAGS (https://src.fedoraproject.org/rpms/fio/blob/ce3c0e65aa7fabdcb82e2735b8232e44b017369c/f/fio.spec#_36 ) which means they also avoid patching fio. It's not necessary to go the same way but I'd recommend using at least --disable-native if aren't using --disable-optimizations and you're distributing binaries widely...
