When I try to buildworld top just shows make sitting there like so:

34791 root        1   8    0   608K   496K wait     0:00  0.00% make

I expect make will sit there as long as I feel like letting it go.

I tried truss but I got an error that it couldn't open /proc/somepid &
ptrace doesn't seem to exist on my system. I was able to use ktrace so I
have a ktrace.out file, but I don't really know what I'm looking at when
I view it with kdump.

What's really extra special weird is that I re-installed the box to
6.0-Beta4 & I was able to run "make buildworld" after I rebooted. Then I
cvsup'ed and now I can't buildworld again.

Any suggestions where I might find somebody who can look at my ktrace.out
file?
