Subject: [2.6.26] ERROR FC host 'qla2xxx' attempted to flush work, when no workqueue created
Date: Tue, 4 Nov 2008 18:26:15 +0100	[thread overview]
Message-ID: <20081104172615.GI23232@vanheusden.com> (raw)
In-Reply-To: <20081104172513.GH23232@vanheusden.com>

While running my http://vanheusden.com/pyk/ script (which randomly
inserts and removes modules) I triggered the folllowing WARNING in a
2.6.26 kernel on an IBM xSeries x3650 (2 quadcores (intel qc x5450)
and 10GB ram).
