autofs stops working after upgrade to 14.10

I use the autofs to mount my home storage into the /net directory. It was working normally until I upgrade to the 14.10 with the following error at terminal:

andre@X61s:~$ cd /net
andre@X61s:/net$ cd stg1
bash: cd: stg1: No such file or directory
andre@X61s:/net$

and in the syslog I got this:

Oct 29 23:22:58 X61s automount[6818]: key "stg1" not found in map source(s).

My /etc/hosts have this content:
andre@X61s:/net$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 X61s

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

192.168.25.101 stg1
192.168.25.111 stg2

And the output of showmount executed at terminal is:
andre@X61s:/net$ showmount -e stg1
Export list for stg1:
/mnt/pools/A/A0/Shows *
/mnt/pools/A/A0/Books *
/mnt/pools/A/A0/Music *
/mnt/pools/A/A0/Series *

Thanks in advance
