Subject: [PATCH 2/22] ppc64: Enable detection bugfix
Date: Thu, 6 Oct 2005 18:25:04 -0500 [thread overview]
Message-ID: <20051006232504.GC29826@austin.ibm.com> (raw)
In-Reply-To: <20051006232032.GA29826@austin.ibm.com>
02-EEH-enable-bugfix.patch
Bugfix: With the curent linux-2.6.14-rc2-git6, EEH errors are
ignored because thier detection requires an unusued, uninitialized
flag to be set. This patch removes the unused flag.
