I sup'd last night (4/24/94), and rebuilt my kernel (I had previously
successfully crossed the river off_t ;-).  It booted fine and appeared
to work great.  I then set things up to rebuilt everything - cleandir
+ all + install.

This ran all night, and this morning I found it churning on

	/usr/libexec/makewhatis /usr/share/man 

(which is odd, since looking around later makes me thing it got a lot 
farther than that, but...)

I opened up another remote X window, fooled around, and the did "ps -axl".
Suddently everything stopped - I looked at the console and found a panic
in vfork.  I believe this was the csh forking ps.

kernel: protection fault trap, code=0
Stopped  at     _fork1+057:    movl    0(%eax),%eax

eax = 0xffffffff

I have not looked at this real hard (I will), but I figured I'd report it.
