Subject: [PATCH] agp/intel: Promote warning about failure to setup flush to error.
Date: Sat,  4 Sep 2010 15:03:27 +0100	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

Make sure we always detect when we fail to correctly allocate the Isoch
Flush Page and print an error to warn the user about the likely memory
corruption that will result in invalid rendering or worse.
