Hello,
This problem was previously described by Neil Conway. All relevant information here:

I still see this very same problem on 2.6.11 vanilla and in Fedora/RawHide hernels. It has haunted me for a couple of months on several Fedora clients. Strangely, a Gentoo client isn't affected, but I couldn't investigate further.
When the current directory becomes inaccessible, it remains so until I cd somewhere else and then cd back to it. Sometimes I must wait a few seconds before cd succeeds.
Here's a sample session:
[executing a find / in another shell to trigger the bug] beetle:/pub/linux/distro/fedora-devel# ll ls: .: No such file or directory beetle:/pub/linux/distro/fedora-devel# cd - / beetle:/# cd - bash: cd: /pub/linux/distro/fedora-devel: No such file or directory beetle:/# [...a few seconds later...] beetle:/# cd - /pub/linux/distro/fedora-devel
Appears to be a client bug. The problem only happens when there's heavy filesystem activity on other filesystems (local or NFS).
NFS mount options: rw,_netdev,rsize=32768,wsize=32768,hard,intr,proto=udp,addr=10.3.3.1
