From b9675136e2ad95156fb93be6155f17590bb26fd7 Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Wed, 6 Dec 2006 20:41:02 -0800 Subject: [PATCH] IPMI: Add maintenance mode Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way.
