This morning I rebuilt NetBSD, including all binaries, libraries, and the
kernel.  I used the most recently sup'ed source (Nov. 6).  I rebuilt all
executables using shared libraries except those in /bin and /sbin and ld,
gcc, and gas.  Yes, I made ld, gcc, and gas before compiling any other 
source.

When booting off the new kernel, I get a panic as soon as I try to start
Xfree 2.0 (which is statically linked; basically, it's the Xfree binaries
that are available on agate.berkeley.edu for NetBSD).

Here's the relevant info from my /var/run/messages:

I got the same result after trying this a second time.

I then booted up using my 3 or 4-day old kernel.  Xfree 2.0 works fine now.
However, before running Xfree 2.0 I tried to "more" a file and got some
sort of ioctl device error; sorry, don't remember the exact message, and
I'm running X now so I can't reproduce it immediately.  I'll try to reproduce
it next time I'm at the console.

BTW, kernel configs are exactly the same.

If this isn't sufficient information, let me know what I need to do (build
a kernel with a debugger?) and if it doesn't take too long, I'll get
more specific info on the panic.
