From 0dfe6e7ed47feeb22f3cf8c7d8ac7e65bd4e87f5 Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Mon, 14 Apr 2014 09:46:53 -0500 Subject: ipmi: Turn off default probing of interfaces The default probing can cause problems with some system, slow booting, extra CPU usages, etc. Turn it off by default and give a config option to enable it.
