From: soma@cs.unm.edu (Anil B. Somayaji) Date: 23 Jun 2001 01:42:38 -0600 Message-ID: User-Agent: Gnus/5.090003 (Oort Gnus v0.03) Emacs/20.7 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 For a while now, I've been running a 2.4 kernel, but (for my research) I need to now run a 2.2 kernel. I was hoping to just run a stock 2.2.19, but I've found that I can't use my CD-RW drive, either as a plain IDE cdrom, or as a scsi-emulated one. (I have ide-scsi, ide-cd, and scsi all as modules.) When I try things as scsi-emulated CD-ROM, I get the following: Jun 22 19:58:15 lydia kernel: ide-scsi: The scsi wants to send us more data than expected - discarding data Jun 22 19:58:16 lydia last message repeated 83 times Instead, if I try ide-cd, I get these messages: Jun 22 20:11:38 lydia kernel: hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command Jun 22 20:11:38 lydia kernel: hdc: status timeout: status=0xd0 { Busy } Jun 22 20:11:38 lydia kernel: hdc: DMA disabled Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command Jun 22 20:11:38 lydia kernel: hdc: ATAPI reset complete Jun 22 20:11:48 lydia kernel: hdc: irq timeout: status=0x80 { Busy } Jun 22 20:11:48 lydia kernel: hdc: ATAPI reset complete Jun 22 20:11:59 lydia kernel: hdc: irq timeout: status=0x80 { Busy } Jun 22 20:11:59 lydia kernel: end_request: I/O error, dev 16:00 (hdc), sector 64 Jun 22 20:11:59 lydia kernel: hdc: status timeout: status=0x80 { Busy } Jun 22 20:11:59 lydia kernel: hdc: drive not ready for command I have these problems with 2.2.1[7-9] & 2.2.20pre5. However, if I add one of the IDE patches, all is well. 2.4 kernels have never given me these sorts of problems. I have a 440LX motherboard (HP Pavilion 8260), hooked up to a Plextor PX-W8432T 4/8/32 CD-RW, attached as /dev/hdc. I also have an OnStream DI-30 as /dev/hdd, and a Maxtor 91020D6 10G drive as /dev/hda. I can live with just running an ide-patched kernel, but it seems very odd that I can't even use the drive as an IDE CD-ROM drive with a stock 2.2 kernel. Is this a bug, or a limitation? I'd be happy to perform any tests to try and track this problem down.
