Nope, nothing fancy going on, just trying to mount and use filesystems
in an ordinary fashion, and never having much luck.
Not that it always corrupts the data on writes, just often enough to
be a pain :-).
I have seen network card issues that corrupted network packets, and if you were
using UDP (no checksums) and had some bad network hardware things could get
ugly, I believe the case I saw they were using TCP, and I have to believe that
the network driver was having issues and the actual checksums weren't getting
done, and there was corruption on the network itself. I was able to change the
behavior by turning off Tcp checksum offload, but there were still issues, and
given my previous experience finding a bug in the offload firmware, I could
believe there were more bugs in it under the correct conditions.
You might check your network stats and see if you are having lots of bad packets
around.
