The way I get a consistant problems is by running bonnie++ with the
line:

strace -o /tmp/bonnie.slog ./bonnie++ -x 1000 \
 -d /afs/test.slac.stanford.edu/ext 2/temp11 -u jgoebel >> /tmp/bonnie.dat

I tested this on the release canidate 2 of 1.2.4 also, but this was
before switching over to ext2. I can run the test today on that
version.

Thanks.
