Interesting: I checked out the sources via cvs, compiled the new kernel and
rebooted the system. uname -r says 3.99.3 rather than 3.0_BETA. Am I missing
something?

Yes, '-r netbsd-3' argument to CVS :)
but 3.99.3 should work too, and has some additionnal fixes.
Long term, it may be better to stay on the netbsd-3 branch is this is intended
to be a production system, though.

Is it possible that netbsd-3 is currently broken? I updated my cvs tree with -r
netbsd-3 a few minutes ago, then ran "config XENU; cd ../compile/XENU ; make
depend" (as usual), but I got the following error:

[...]
mkdir xen-ma
ln -s ../i386 xen-ma/machine
depending the kern library objects
depending the compat library objects
make: don't know how to make machine/intrdefs.h. Stop

make: stopped in /usr/src/sys/arch/i386/compile/XENU

Creating a link from sys/arch/i386/include/intrdefs.h to sys/arch/xen/include/
fixed the problem with "make depend", but during "make", I got another error:

[...]
mkdir xen-ma
ln -s ../i386 xen-ma/machine
making sure the compat library is up to date...
make: don't know how to make ../../../../../../sys/selinfo.h. Stop

make: stopped in /usr/src/sys/arch/i386/compile/XENU/lib/compat
*** Error code 2

Stop.
make: stopped in /usr/src/sys/arch/i386/compile/XENU

This time, selinfo.h appears to be completely missing from the src/sys tree.

Oh, I guess for tonight I'll just stay with 3.99.3. :)

Thanks for your help,
Marcello
