The connection was reset by the server (see 104 in /usr/include/asm/errno.h)

and smbmount was unable to reconnect in time, so the lookup returns EIO.

Why smbmount fails here I don't know. You can look at your samba logs and
see if smbmount.log contains anything.

What kernel is this?

After a -5 does the mount start working again or does it remain unusable
until you umount it?

The indirect cause is that the server disconnects and that can usually be

One trick is to make a cronjob that reads or writes something from the
share at regular intervals (say every 5 minutes). That will make the
server think you are using it and not disconnect it.

The other is to make a registry change to increase the "autodisconnect"
time of the NT/2k/XP server. I don't have that key available, but it is
described in the MS knowledge base (and has been mentioned on this list if
you search the archives).
