From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ivo Santos Cavalcante Carneiro Subject: unable to mount cdrom/cdrw using scsi emulation Date: Fri, 19 Sep 2003 14:39:23 -0300 Sender: linux-scsi-owner@vger.kernel.org Message-ID: <3F6B3F4B.8080503@ig.com.br> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Return-path: Received: from smtp-26.ig.com.br ([200.226.132.160]:23456 "HELO smtp-26.ig.com.br") by vger.kernel.org with SMTP id S261651AbTISRkd (ORCPT ); Fri, 19 Sep 2003 13:40:33 -0400 List-Id: linux-scsi@vger.kernel.org To: linux-scsi Sorry, I'm not sure this is the right place to send this, but case not, please discard this mail. I'm having some problem when trying to mount cdrom: I receive an error message and am still unable to read from cd at the mount point. It's possible to execute a music disc from the drives. I've a cdrom drive and a cdrw drive and none of them work. All two drives work fine using ide-cd (ATAPI) driver. I've made a complete bug report, but I'm not sure this is the case, so this mail contain only the error messages. P.S.: sorry by the poor english. TIA, Ivo These are the messages retrieved from kernel log: ******** Aug 31 19:50:43 serv kernel: ide-scsi: The scsi wants to send us more data than expected - discarding data Aug 31 19:50:43 serv kernel: ide-scsi: [[ 28 0 0 0 0 10 0 0 1 0 0 0 ] Aug 31 19:50:43 serv kernel: ] Aug 31 19:50:43 serv kernel: ide-scsi: expected 2048 got 4096 limit 2048 ******** This message appear many times on kern.log - I've noticed a number, on the second line, changing from 10 to 63 in hexadecimal notation.
