autofs/nfs issue with Fedora 16

[Richard Shaw]

I use autofs to mount a nfs share that contains both the contents of
the various Fedora install DVD's and packages I've built for a local
repository. This has worked quite well on all my Fedora 14 & 15
machines.

I updated my laptop to Fedora 16 and it's having trouble see below:

[richard at laptop local]$ ll
total 0
drwxr-xr-x. 2 root root 0 Nov  6 08:46 gramps
drwxr-xr-x. 2 root root 0 Nov  6 08:46 packages
[richard at laptop local]$ cd packages/
bash: cd: packages/: No such file or directory
[richard at laptop local]$ ll
ls: cannot access packages: No such file or directory
total 0
drwxr-xr-x. 2 root root 0 Nov  6 08:46 gramps
d?????????? ? ?    ?    ?            ? packages
[richard at laptop local]$ pwd
/net/hobbes/var/local

As you can see when I first cd into /net/hobbes/var/local I can see
the packages directory, but when I try to cd into it I can't and then
ls'ing again shows strange output.

Any ideas?

Contents of /etc/exports on hobbes:
/var/local/packages                     192.168.0.0/24(ro,sync,all_squash)
/var/local/gramps                       192.168.0.0/24(rw,sync)

Thanks,
Richard
