Venus returns ENOTCONN, I have seen this a couple of times, but haven't
even looked at where it is coming from.

This is because there is probably some skew between a structure in the
kernel and in venus. It is actually non-fatal, because venus doesn't
really need all 8468 bytes. The latest test9-pre5 contains a fix for
this, but has a nasty Oops. The patch for that is already sent off to
Linus, so test9-pre6 or test9-final should be working like a charm.

Coda's kernel module accesses files on a very low level using
generic_file_read/write/mmap. This is definitely broken for reiserfs on
2.2 kernels, and I am unsure if it would work reliably on 2.4.

My best advise at the moment is to keep venus.cache in an ext2 formatted
partition.
