Description of problem:
We have a Quantum SNAP server model 4100 acting as an NFS server to a number of
RH 8 clients.  Installing kernel 2.4.20-19.8 caused read errors on the clients.
 The problem seemed to only affect a directory containing a large number of
small text files, as opposed to another directory containing a similar number of
large files.  'grep'-ing for a string in the text files reliably caused I/O
errors.  I didn't see the problem when an RH8 server was serving an RH8 client.
 The SNAP server is running Quantum's latest version of its OS.

I'm certain the problem is the 2.4.20-19.8 kernel.  Backing up to either one of
RedHat's own 2.4.18 kernels or manually installing the stock 2.4.21 kernel built
with RedHat's configuration file fixed the problem.

I've verified the problem on Athlon, Athlon MP, Pentium 1 and Pentium 4
architectures.

Version-Release number of selected component (if applicable):
kernel-2.4.20-19.8

How reproducible:
Always

Steps to Reproduce:
1. Install 2.4.20-19.8 kernel on an RH8 system
2. Set up a Quantum SNAP server as an NFS server to the RH8 system
3. Populate a directory on the Quantum with a large number of text files.  I'm
using files a few KB in length each.
4. grep for a string in those text files.
    

Actual Results:  Repeated "input/output" error reports

Expected Results:  No such errors
