I am seeing the same problem on 7.0-RELEASE, I also noticed that it only 
seems to be on pkg_add's with multiple packages selected.  As "up-enter" 
gets me past the problem, it's not critical, but I thought I report I 
saw it too.  Mine machine is a dual-core AMD X2, and I'm using ZFS (so I 
don't think fsck will help). 

This machine is a fresh install.  Just wanted to point out that whatever 
the problem is, it made it in the 7.0 release.
