I'm having issues with at least -fno-schedule-insns -- where in the arch/um/Makefile do I make the change as well (or do I?) So I tried the following combos: perl -e 's/-O2/-O2 -fno-schedule-insns/g' -p -i.bak Makefile arch/um/Makefile perl -e 's/-O2/-O2 -fno-schedule-insns2/g' -p -i.bak Makefile arch/um/Makefile perl -e 's/-O2/-O2 -fno-schedule-insns -fno-schedule-insns2/g' -p -i.bak Makefile arch/um/Makefile No dice on any of them. I don't believe there is a -O2 in arch/um/Makefile as there is in 2.6.6 -- should I make a change to the CFLAGS there? ------------------------------------------------------- This SF.Net email is sponsored by the new InstallShield X. >From Windows to Linux, servers to mobile, InstallShield X is the one installation-authoring solution that does it all.
