I copy a file from a Ubuntu 10 machine with openafs-client 1.4.12+dfsg-3 and
read it from a Scientific Linux 2.6.18-128.7.1.el5 machine with
openafs-client-1.4.12-el5.1.1. The checksum is wrong on the reading end, and it
changes to a different wrong checksum every time I re-do the copy.

The AFS copy always differs at the same place:
arctura> cmp /tmp/IMG_0347.JPG
/afs/afsdemo.cit.cornell.edu/users/rcc2/Cornell/pix/stairs/IMG_0347.JPG
/tmp/IMG_0347.JPG
/afs/afsdemo.cit.cornell.edu/users/rcc2/Cornell/pix/stairs/IMG_0347.JPG differ:
byte 1257, line 6
At the reading side, the file always has the same number of bytes as the original.
