What's probably happening is that the controller misses and interrupt,
the reset happens (thus tossing the data transfer), and the FFS code
gets confused as a result.

I remember Chuck mentioned some lost interrupt problem to me some time
ago, and he added the watchdog timer to get past the missed interrupt.
I don't believe he's found the bug that causes it yet.  I recall someone
here on port-sun3 had the same problem (I'm sorry, I don't recall exactly
who it was), and was looking into it...
