Optimization levels beyond -O are known to generate incorrect code. You will end up with an unbootable or, worse, an incorrect kernel as a result. If you are having compile problems with anything but -O, revert to -O. If you are still having problems, wthen we'll talk. Youre _are_ following the instructions in /usr/src/UPDATING on how to upgrade from -STABLE to -CURRENT, right? -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
