Additional Information:
This is a known issue that affects the smbfs in the kernel and samba. To fix it patches will need to be applied to both the kernel and Samba. They 
can be found at http://www.hojdpunkten.ac.se/054/samba/index.html. Apply 00 through 02 to the kernel. Apply smbmount-2.2.3a-negotiate.patch to Samba.

switch to smbfs mount, 2 GB barrier started to bully me.
