I have a 3/260 mounting netbsd source from an ss2 (currently
with its own problems, but thats another matter :), it then
union mounts that under /usr/src (so all the nfs traffic is read
only), and I then try a 'make build' - and bingo, core dumps!
Its reproducable to the extent I've never got through a 'make &&
make install' in /usr/src/lib without a coredump, but unpredictable
as to where it will happen.
Now the sun3 used to be next to the ss2 and never had a problem
(that I noticed), now its across the campus on a subnet with a
lot of loud machines (the entire CS department), and now I get
code dumps...
If anyone has any ideas I'm happy to try anything out - up to and
including causing panics at any given point... (After my sparc
problems I'd like to help fix _something_ :)
