I see this all the time.  I just assumed that something the MacOS to unix
swap over isn't being done in the right order. (possibly interrupt
vector replacements ?).
If a packet comes in on LocalTalk it jumps to the old interrupt
vector in the MacOS which is no longer there and boom.
If you get lucky the packet hits a little later and it jumps to the
new interrupt vector in the unix serial driver.
Just a theory.
