I'm getting the same problem doing a `make buildkernel KERNCONF=GENERIC` on an amd64 system (Intel core i5 4-way): : $ as --version : GNU assembler 2.17.50 [FreeBSD] 2007-07-03 : Copyright 2007 Free Software Foundation, Inc. : This program is free software; you may redistribute it under the terms of : the GNU General Public License.

I did a cvsup this morning to pull me to the most recent source code level, and still have the same problem. Ideas? Questions? This appears a bit more pervasive than I had initially thought, if this Joe User here (well, Joe Sysadmin) is getting caught by it. Thanks, and 73, de -- Mike Andrews, W5EGO mikea@mikea.ath.cx Tired old sysadmin
