Sorry, I don't have an answer for you. However, I can tell you that I
have experienced the exact same problem with two Snap servers (model
4100), using Fedora Core 2/3, kernel 2.6.? through current 2.6.11. One
of the Snap servers is running software version 3.4.803, but the other
was recently upgraded to version 4.0.855 and the problem still exists.
Mounting as a cifs file system, as someone suggested, doesn't really
help, at least not for me. I don't get the hard lockups like I do with
smbfs, but as soon as I try to browse beyond the root directory of the
share the process just hangs; although other applications still
function. This seems to be a kernel 2.6 issue, as I have used similar
mounts on RedHat 7-9 and Fedora Core 1 systems without any problems. I
ended up having to use NFS. If you ever find a solution I would be
interested in hearing about it.
