Certainly it would be a nice idea. We have plenty of cases where a
-CURRENT system might have difficulties booting. In general we solve
the problem in one of two ways:
1. Build a kernel with debugger support and analyse what the problem
2. Work around it long enough to get the system to a point where you
can take dumps. This is the approach Alfred is suggesting.
I don't think this has much to to with the current situation: based on
the evidence we have seen, it seems that Tony has tried to boot a
release snapshot of -CURRENT. It failed. Coincidentally, he has also
disabled IDE support in the belief that this might buy him something.
Now he comes and claims that there is a connection between these two
events, but he doesn't give us any evidence.

I don't think anybody claims you're seeing things.

Maybe you should change the teflon cables.

For public record: we are not producing an OS that does not boot.
We're prepared to believe that you're unable to boot it, but you're
not doing anything to get people to help you.

No, of course not. In fact, saying things like that really discredits

A typical machine nowadays has 128 MB of memory. That would just
about fit on an LS-120, but you'd need about 90 floppies to dump to.
That doesn't make sense.
My personal feeling is that you should take Alfred's advice and try to
boot without disabling IDE. It may or may not work. If it doesn't,
you'll know you're wrong about connecting the two events. If it does,
it'll give you a system which is usable for debugging the problem.

I thought we were talking about a product, not a problem you're
Maybe it's time to remind people about -CURRENT:
Many users compile almost daily from FreeBSD-CURRENT sources, but
there are times when the sources are uncompilable. The problems are
always resolved, but others can take their place. On occasion,
keeping up with FreeBSD-CURRENT can be a full-time business. If you
use -CURRENT, you should be prepared to spend a lot of time keeping
the system running.
In particular, note who should be doing the work: the people who have
the problem. It doesn't do any good to thrash around, make
unsubstantiated claims and blame other people. On the contrary, it
makes people think you're a jerk.
