Description Andrew Merrill 2004-01-28 18:37:43 UTC
Description of problem:

We have AS 2.1 on several two and four way Dell systems.  We upgraded
four systems from revision 27 of the enterprise kernel to revision 35.
 We noticed immediate network performance degredation on the four
upgraded machines.  We were able to narrow this down to NFS operations.

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

How reproducible:


Steps to Reproduce:
1.  On system with v 35 kernel initiate NFS operations
2.  On same system reboot with v 27 kernel
Actual results:

We were not able to quantify how much slower machines with the v 35
kernel were, but it was large orders of magnitude.  Booting with the
system with the older revision immediately fixed the problem.

Expected results:

This has long been fixed in the current erratum kernel, e.38
