Subject: [patch 1/2] PNP: revert Supermicro H8DCE motherboard quirk
Date: Tue, 11 Mar 2008 15:24:40 -0600 [thread overview]
Message-ID: <20080311212740.422339886@ldl.fc.hp.com> (raw)
In-Reply-To: 20080311212439.293001409@ldl.fc.hp.com
[-- Attachment #1: pnp-remove-supermicro-quirk --]
[-- Type: text/plain, Size: 2325 bytes --]
There are other systems with similar problems
(http://lkml.org/lkml/2008/1/27/168), so we need a more
generic quirk. Remove the Supermicro-specific one first.
