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) -- ANTONY T CURTIS Tel: +44 (1635) 36222 Abacus Polar Holdings Ltd Fax: +44 (1635) 38670 > Endless Loop: n., see Loop, Endless. > Loop, Endless: n., see Endless Loop. > -- Random Shack Data Processing Dictionary To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
