I have a scsi card with a cd-rom and a scanner. And I also have a
ide cdrecorder.

I have compiled in support for scsi-emulution, and scsi-cdrom and generic
scsi support.

When I start up the machine I get:

SCSI subsystem driver Revision: 1.00
scsi0 : AM53/79C974 PCscsi driver rev. 0.5; host I/O address: 0xc800; irq:

if I run

cdrecord --scanbus

I get:

My scanner and My ide cd-burner disapear after a while.

If I instead compile all scsi things as modules it works just after I have
loaded the modules so I have to load and unload the modules all the time.

Is this something due to devfs ? How can I solve this?
