 a quick dip into the code:
 
         int wx = (SMB_CAPS(SSTOVC(ssp)) & SMB_CAP_LARGE_WRITEX);
 ...
         if (wx)
             error = smb_smb_writex(ssp, fid, &len, &resid, uio, scred);
         else
             error = smb_smb_write(ssp, fid, &len, &resid, uio, scred);
 
 and write contains:
         /* Cannot write at/beyond 4G */
         if (uio->uio_offset >= (1LL << 32))
                 return (EFBIG);
 
 So either the check is wrong (there's SMB_CAP_LARGE_FILES too), or it's
 not getting detected properly.  Either way, should only be a minute or
 two of debugging (with rump_smbfs, of course ;) or specreading.
