Description of problem:
ls -l against nfs mounted cdrom image (/mnt/foo/testdir) eventually fails 
with 'ls: .: No such file or directory'. A cd /mnt/foo/testdir is required to 
re-establish the current directory.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.on anyhost:
mount -t iso9660 -o loop image.iso9660 /mnt/cdrom.image
image.iso9660 is ~264 MB.

2.on client:
mount -t nfs anyhost:/mnt/cdrom.image /mnt/foo
/mnt/foo/testdir has ~50 RPM files.

3.test script:

cd /mnt/foo/testdir
while [ 1 ]
  ls -l


Actual Results:  after 8 minutes or less, the test case returns the below 

ls: .: No such file or directory
ls: .: No such file or directory
ls: .: No such file or directory
ls: .: No such file or directory

Expected Results:  Normal ls -l output showing 50 RPM files

Additional info:

System on which the image.iso9660 resides (anyhost) :
 Vendor: GenuineIntel
 Model:  Pentium III (Coppermine)
 Speed:  801.839 MHz
 Cache:  256 KB
 Memory: 128 MB
Linux  2.4.9-13 #1 Tue Oct 30 20:11:04 EST 2001 i686 unknown

Client system using NFS to access remote cd image was RedHat 8.0

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
