Interesting, how are you getting these power failures? bad battery?

Your client dies when it tries to replay the logged operations. I
thought that even though we sync less frequently, that the log would
remain internally consistent. We might miss a couple of updates but it
would be a consistent snapshot of some valid state maybe 5 to 30 seconds
before the system abruptly died.

RVM doesn't have the best debug messages. I can see that it got past the
point where it successfully opened the log but fails while it tries to
replay any logged, but uncommitted operations.

One thing I notice is that RVM_EINTERNAL is returned when the timestamp
of the last write operation in the log is more recent than the current
system time. I wonder if your notebook has a clock that is running fast
(or a cmos clock that is slow) so that the time jumps back after a
system crash.

If you install rvmutl (from the rvm-tools package ) you could run

    # rvmutl
    > o /usr/coda/LOG
    > status

And that should tell us when the last write was committed so we can
compare that with the system time if the EINTERNAL error hits again.
