Sorry I'm a few days late on this, but where is scsibus1? This looks
like a real CSI system with disk drives, and I don't see the bus or
anything on it. You did have hdd=ide-scsi (or hd?) and load the module
for ide-scsi, right?

 On the machine where it does not work I have a couple of scsi hard
 drives.  I think by default the ide-scsi part is pointing to /dev/scd0
 which could conflict with where the scsi disk is?  Do I need to point
 the ide-scsi driver to a location and if so, how do I do that?

Well I would assume it is getting confused since it already has a
scsi adapter loaded.  Is sr_mod and sg even modules in the kernel?
Perhaps if you just FORCED ide-scsi to load on boot, instead of trying
the messy modprobe mess you have, it might work better.  And there is
nothing wrong with using ide-scsi for all your ide cdrom drives, even
the non cd-rw ones.  So if you simply use rc.modules or /etc/modules or
whatever your distribution has, to force load ide-scsi on boot, then sg
and sr_mod should auto detect the drives when needed.
