Sounds like a problem that I have here.  If I turn off the L2 cache NetBSD
1.0 is *really* stable.  However, if I turn it on, it will crash at a
random point in the kernel.  (User programs die too).  Seems like something
in my setup (16MB, 1542C, GUP-2MB) is conflicting.  Really wish I knew what
it was.  Linux (evil word) seems to be fine on this hardware, as was a
version of NetBSD before 1.0.  Queer.
