Description Simon 2010-05-20 14:15:08 UTC
Description of problem:
Average load never falls below about 0.50 when idle even though no obvious resource usage (top/atop/vstat, etc.). When booting older kernel with otherwise identical system, load is 0.00 when idle.

Version-Release number of selected component (if applicable):
2.6.18-194.3.1.el5 (high load)
2.6.18-164.15.1.el5 (normal 0.00 load when idle)

How reproducible:

Steps to Reproduce:
1. Install i386 2.6.18-194.3.1.el5 and reboot system
Actual results:
Load average always above about 0.50, regardless of running software

Expected results:
Load falls to near zero when idling.

I should add that this *only applies* to the i686 kernel. I've other x86_64 installs running the same kernel release (2.6.18-194.3.1.el5) which report normal (0.00) loads when idle.

This bug/component is not included in scope for RHEL-5.11.0 which is the last RHEL5 minor release. This Bugzilla will soon be CLOSED as WONTFIX (at the end of RHEL5.11 development phase (Apr 22, 2014)). Please contact your account manager or support representative in case you need to escalate this bug.

Comment 3 RHEL Program Management 2014-06-02 13:23:25 UTC
Thank you for submitting this request for inclusion in Red Hat Enterprise Linux 5. We've carefully evaluated the request, but are unable to include it in RHEL5 stream. If the issue is critical for your business, please provide additional business justification through the appropriate support channels (https://access.redhat.com/site/support).

OK. This isn't major for me.
