In order to get the ipf related fixes, I sup'ed sources from the
release branch and configured and build a GENERIC kernel. The kernel
will not boot, it hangs/freezes after the loader displays
start=0x10000. I have done a successful 'make build' in /usr/src to
bring userland up to 1.4.1release-branch level - still no luck
building a working release branch kernel. I have no problem building
kernels form the 1.4.1 release sources.

The machine is a 7300, output from a 1.4.1 release kernel is below.
It's a GENERIC kernel, plus puc devices.

What can I do to track this down?

BTW, I thing we should change the version number for the
release-branch source to something like 1.4.1A - right now it's just
to easy to confuse 1.4.1 release and release branch.
