:Using -O2 in your make.conf causes unpredictable system

:-DR

    make.conf's CFLAGS flags shouldn't be inherited by the kernel builds,
    but Dave has a good point.  If you are using anything other then -O to
    build your kernel, rebuild it with only -O -pipe and no other specific -f
    optimizations.  Definitely get rid of -funroll-loops.

    I don't trust gcc2's -O optimizations at all.  Also, using -O3 under
    GCC3 (or using GCC3 generally) is also considered to be experimental.
