Huh? Date: Thu, 18 Oct 2001 18:08:43 -0500 X-Mailer: KMail [version 1.2] MIME-Version: 1.0 Message-Id: <01101818084300.01082@mercury.snydernet.lan> Content-Transfer-Encoding: 7BIT Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Below are the messages related to my SCSI devices that I see when booting kernel v2.4.12. Note that last device, scsi1:A:5:0. The last 3 of the 5 devices listed (CD-ROM, tape drive, DVD-RAM) are all on a single SCSI-2 chain, so by definition they are accessed as 8-bit devices. So why does scsi1:A:5:0, the DVD-RAM, report this: refuses WIDE negotiation. Using 8bit transfers The only distinction I can see in these 3 Ultra SCSI devices is that the DVD-RAM is external where the CD-ROM and tape drive are internal. Anyone know why this refusal is reported? Thanks. ------------------------------ SCSI subsystem driver Revision: 1.00 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.1 aic7896/97: Ultra2 Wide Channel A, SCSI Id=7, 32/255 SCBs scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.1 aic7896/97: Ultra2 Wide Channel B, SCSI Id=7, 32/255 SCBs (scsi0:A:6): 80.000MB/s transfers (40.000MHz, offset 63, 16bit) Vendor: QUANTUM Model: ATLAS_V__9_WLS Rev: 0200 Type: Direct-Access ANSI SCSI revision: 03 (scsi0:A:8): 80.000MB/s transfers (40.000MHz, offset 63, 16bit) Vendor: QUANTUM Model: ATLAS_V__9_WLS Rev: 0200 Type: Direct-Access ANSI SCSI revision: 03 scsi0:0:6:0: Tagged Queuing enabled.
