I actually used this: CFLAGS ?= -O -pipe -mcpu=i686 -march=i686 COPTFLAGS ?= -O -pipe -mcpu=i686 -march=i686 All the diffs in sys/ on the box I built this kernel on are at http://www.FreeBSD.org/~jhb/patches/sys-mutex.patch. One possibly notable patch I had forgotten about is the fix to forward_signal() to lock with sched_lock. I've just committed that though. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
