>Description:
	
If I do a `make build` on above system, it will freeze at random points
earlier or later. Even if I compile the kernel with ddb enabled I can not
break into the debugger when the system froze.

If the system is just left idle it will stay up. So I *guess* (read: just
esoterik, not know) that its releated to heavy IO.

My HP9000/400T does not show this effect with the same sources, so I *think*
its not an m68k bug, but amiga specific.

Unfortunalty I was not able to compile a kernel with DEBUG, see my other pr
for more info.

>How-To-Repeat:
	
Try `make build` in /src from 19.09.1999, sooner or later the machine
freezes.

>Fix:
	
No idea.
