-----BEGIN PGP SIGNED MESSAGE-----
Hi all. I just recently got a digital RRD40 SCSI CD-ROM drive to play with. I have a fairly standard Gateway 486/33, 2 ide hard drives, modem, and AHA-1522B SCSI controller. The only other device on the SCSI chain is a zip drive. Anyway, if I boot with the digital cd-rom powered up, the kernel takes a long time after the "scsi: 1 host" message, then spews forth the following:
scsi: 1 host inbound message (MESSAGE REJECT), inbound message (MESSAGE REJECT), Vendor: DEC Model: RRD40 TM DEC Rev: 280E Detected scsi CD-ROM sr0 at scsi0, channel 0, id 1, lun 0 Vendor: IOMEGA Model: ZIP 100 Rev: R.41 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi removable disk sda at scsi0, channel 0, id 5, lun 0 scsi: detected 1 SCSI cdrom 1 SCSI disk total.

Sorry for leaving out the registers and the stack. None of this is in any logs, so I had to write all of it down by hand, and the stack/registers have a lot of nasty numbers. If they are needed/will help much I can get them without trouble. This happens every time I boot with the CD drive on. All functions in call trace and EIP are from System.map. I've only had this card for about a month, so I'm rather new to SCSI stuff. If there is a dumb configuration mistake I've made, please just let me know. I haven't really diddled at all with the configs on the AHA-1522B. And I have checked the devices sr* and scd* in /dev, and they all are major 11, minor ([0-7] for scd*, [0-2] for sr*).
That is all I have prepared for now. I don't subscribe to linux-scsi, so if anyone there responds, please cc to me (or linux-kernel if appropriate).
On a happier note, I have been running 2.0.xx since release, and this is the first problem I've had. Great job everyone!

P.S. I can use my ZIP drive without problems, as long as the cd drive is off. Both are connected to the chain now, with the cd off.
