Hm, can it be that the console output driver just hangs sometimes?
That has happened before, and jumping into the debugger and back solves the 
problem.

I just had a "hang" in a native build. Just entering and leaving the
debugger didn't help, but single-stepping around a bit (into the console
interrupt handler) got the system out of the "hang".

Johnny, could this be the problem you saw with long-running native
builds?

So it would seem. Stepping on a little in ddb, and then continuing got it running again.

My build was aborted, but the machine is alive again.
(The build stopped with a signal 5, well lint did.)

Interesting. So it appears we have some problem with interrupts being locked out, and eventually not even being restored at all. I seem to remember something about a change to the splxxx() calls a while back. That could be the problem here...
