Subject: DMAR ERROR by nVidia video card
Date: Sun, 15 Mar 2009 21:04:21 +0900	[thread overview]
Message-ID: <d5dec53b0903150504v9843fefr939f0a0cbc8a300f@mail.gmail.com> (raw)

Hi

I enabled DMAR by kernel parameter, and started X windows.
The following error message is reported forever.
Is this driver's issue?
