This problem has plagued me from the beginning of the sun3x port.  I too
have the same problem when doing a 'make build'.  The only workaround is
to type 'make build' again after rebooting.

I spent some time talking to Jason Thorpe about the possibility of this
problem being the symptom of a kernel memory leak.  'make build' is a very
process intensive application; that is, if forks many many processes over
its lifetime.  This leads me to believe that if there is a memory leak, it
is most likely to be found in the process clean-up code in the kernel.

For now you must live with the agony and wait of typing 'make build'
again.
