Well, there were a raft of changes to the zs driver, which I assume is
what your PPP is running through to talk to the ISDN modem. Mycroft's
fixes substantially improved the performance and cut the number of fifo
overflows dramatically, the latter of which could easily be the cause of
your checksum errors.
The latest sun3 snapshot it about 2 days too old for these changes to be
included, as verified a few moments ago.
