This looks like it could be related to the Intel CPU topology change that was recently MFC'd: http://freshbsd.org/2010/11/01/08/20/14 Can you please roll your source code back to a date prior to the above commit, rebuild, and re-try? You can accomplish this using the "date" option in your cvsup/csup file. See csup(1) for details. I would recommend also chopping off an additional hour "just in case". -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
