Hello,

I installed the May 28 snapshot on a pentium class machine (Cyrix, actually)
from scratch.  The install went ok (except that the screen output was
corrupted, like \r's were missing somewhere), but when I NFS mount a disk
to this system and try to build pkgs, I get panics all the time.  Here's one:

kernel: page fault trap, code=0

I'm using the default kernel installed by sysinst.  This same panic seems
to occur almost every time I try to build a pkg (I managed to build
pkginstall and pkglibtool, but that took three reboots already).  I think
it has always been the same instruction causing the panic (at least it's
been the same routine every time).

This machine was rock solid with 1.4.2 (I was running X and doing compiles
on it), so I think it's some kind of a software problem.

Any ideas?  I don't think I could even build a kernel on this system (and
all my other machines are running 1.4.2 or older).

Thanks,
