could you give us the output of `ls -laT /usr/bin|grep gcc` and also can you send us the CU features which get reported? (dmesg -a) i think core2 only gets enabled with native, if sse3 was detected. maybe freebsd isn't properly detecting sse3 support for your cpu. i'll rebuild gcc later on and check whether i experience the same issue. cheers. alex > > Regards -- a13x _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
