Description of problem:
When copying, unzipping, untaring large files (1.8GB) there is intermittent 
data corruption. The file sizes are the same but when diff or cmp is run there 
are 4 to 8 bytes of corrupt data. The problem was reproducible on 3 separate 
machines, and rebooting the servers fixed the problem temporarily. We’ve run 
hardware diags on all 3 machines with no failures. The servers are:

Compaq DL380s 6GB RAM 
2 Intel Xeon 2.8GHz processors

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

How reproducible:

Steps to Reproduce:
1. cp 2-gig-file 2-gig-file.new
2. cmp -l 2-gig-file 2-gig-file.new

Actual Results:  Displayed several lines of differences.

Expected Results:  Should have returned nothing. I.e. no difference in files.

Additional info:

All machines have the CD versions of all RPMS. Only the Enterprise kerel has 
been upgraded to e.18

Upgrading to the e.27 kernel seems to have fixed our problem.
