Just as a sanity check, I adapted my patches to 1.5 release and cross
compiled it on my Sun 3/80 (which took the last several hours).
Unfortunately, it hangs in the exact same place.  Only problem now is
that hard-break doesn't drop to DDB as in 1.5R (yes, I have DDB enabled
in the kernel conf).  So I can't even see what the heck is going on.
For what it's worth, the machine isn't ping-able, like before, so without
DDB I guess it's printf time.  :(
