Load the ncr53c8xx SCSI module - are you sure the system won't use
sym53c8xx? - and then create a new ramdisk image file using mkinitrd.
That will see the scsi_hostadapter entry in modules.conf and include the
scsi modules in the new initrd.img.

I don't know, kudzu put in ncr53c8xx in modules.conf but I can take a
look at the other driver if that is equivalent or better of course.
And thanks for the answer, it makes perfect sense that the thing needs
to go into the initrd of course!

I got the same problem:
Two servers, one running RH9 with LSI scsi (ncr53c8xx) card and one (to
replace the RH9 server) running FC1 with the same scsi card. I have a
DDS-3 tape drive connected to that card.
On RH9 I do not have a cd-writer on FC1 I do.
At boot time the ncr module is loaded and then unloaded (if I read the
messages below correctly). insmod of the ncr53c8xx module and the st
module makes the tapedrive available to the system, on RH9 this is done
automatically.

Lines from the messages at boot time:

I'd like to know how to solve this the correct way, my guess is it has
something to do with the ide-scsi emulation for the cd-writer (that's the
only real difference in my setup).

Any tips would be nice!

An easy way to test if the cdrw is triggering something weird. Disconnect it for the next boot and see if the same thing occurs. If things stay the same, the cdrw is not the cause, but if they change then it would seem they are interacting.

You do not say if the cdrw is IDE or SCSI, but I suspect it is IDE or you would not be using ide-scsi.

TIA
