Description Joshua Giles 2008-04-17 14:10:13 UTC
Description of problem:
When irq runs on a system with two cpus, it quickly exits not reporting any
reason as to why.  Practically speaking, irqbalance doesn't have much work to do
on a system that has only one cache domain and it's job is to spread irq's
across the available domains in the system.  However, this will cause confusion
in the minority of our customers and will trigger some support calls.  To avoid
confusion I propose documentation that describes expected behavior on systems
with only one cache domain and possibly a pointer to the documentation @ the
irqbalance project page.

Version-Release number of selected component (if applicable):
0.55-10.el5

How reproducible:
100%

Steps to Reproduce:
1. Run irqbalance on a system with <= 2 cpus or 1 cache domain
2. Check daemon status after a few seconds
3.
  
Actual results:
Program exits

Expected results:
Continues to run or report it has nothing to do.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
