I have world compiled with -O2 with no ill effect (that I have noticed)
but if I compile the kernel with -O2, it looks okay but has problems
with talking TCP/IP - seems to generate faulty checksums and some other
quirks.... To put it simply, stable kernels are only with -O (in my
experience)
(however, I have compiled KLDs with -O2 with no ill effect)
