If you are listening, perhaps you and Bill should touch bases on this?

FWIW, since upgrading both client and server to kernel 2.1.86, things have
become a LOT more stable.  I actually built the kernel 5x in a row this
past weekend without corruption.  Only a couple of the above messages
popped up.

I would still love to know why "make" gets confused building on Coda.  It
always thinks that the entire kernel tree is out of date, and starts over
from the raw beginning every time.  Any guesses?
