[Samba] smbmount hung after mounted

[nina]

 From my redhat9, I tried to mount the network disk from the FC2 system 
, after mounting, most of the time it just stay there until I press 
Ctrl_z, or Ctrl_c, however, the disk is mounted successfully ( somtimes, 
it got through and give me the prompt without pressing Ctrl_c.)
*#smbmount //server/folder1 /Shared -o         
credentials=/root/smb_shared,uid=general,gid=group,fmask=660, dmask=770

/INFO: Debug class all level = 2 (pid 5476 from pid 5476) added 
interface ip=66.80.30.160 bcast=66.80.30.191 nmask=255.255.255.224/
*
then wait for ctrl_c. Did I miss anything here?
