smbfs mount wedges

I have this line in my /etc/fstab:

//ivoras_at_server/share  /home/ivoras/mnt  smbfs rw,noauto,-f640,-d750 0 0

But the command

# mount /home/ivoras/mnt

doesn't exit. The file system is mounted, I can see it in output of
"mount" on another console, and I can access the files in it without
problems, but the "mount" command never returns. It's stuck in state
"devdrn", and can't be killed by SIGINT or SIGKILL.

This is a -CURRENT from few days ago.

Does smbfs work for someone?
