From: Michael Barker To: linux-kernel@vger.kernel.org Content-Type: text/plain Content-Transfer-Encoding: 7bit X-Mailer: Ximian Evolution 1.0.5 Date: 28 May 2002 22:10:09 +0100 Message-Id: <1022620209.1368.17.camel@corona> Mime-Version: 1.0 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Keywords: Modules Ooops CD-ROM DVD Hi, Currently running Redhat 7.2 (uname = 'Linux corona 2.4.7-10 #1 Thu Sep 6 16:46:36 EDT 2001 i686 unknown'). AMD 1600, Asus AV333 Motherboard, MATSHITADVD-ROM SR-8587, ATAPI CD/DVD-ROM drive. I get the following Ooops on booting (output below). The CD-Rom will become unusable and the ide-cd module will remain in the initalising state (judging by the output from lsmod). It occurs intermittantly, a reboot has so far fixed the problem. It has occured twice in the last 6 or so boots of my machine. If you need any more info let me know. I am not on the lkml so if you could cc me in the reply that would be appreciated.
