I couldn't cp(1) a file from the smb share to local disk, whereas if I used dd(1) I was able to get the file without problems.
The funny thing was that my laptop runs the same config (freebsd 5.3-stable but from a build of 2 days earlier) and it has no problems with the smb mount.
I couldn't understand why my gateway box was having these problems until I took a closer look at how my LAN NIC was configured.
I had been experimenting with GbE and set the mtu on the LAN NIC to 9000 for some jumbo frame test work and somehow the smbfs implementation (either statically compiled into my kernel of simply by loading smbfs.ko) has problems with this mtu size.
I switched back to the original mtu setting of 1500 and now smbfs works as expected.
