I was running 2.2.18 and everything was working fine. I upgraded to 2.4.3-pre3 and for some unknown reason the kernel will not recognize one particular CD drive on my SCSI chain. I doubt it's hardware related because switching to the old kernel resolves the problem. Furthermore, the other SCSI devices on the chain are recognized by 2.4.3 indicating that the controller is properly compiled and can be accessed. Dmesg in 2.2.18 shows all three scsi devices, dmesg in 2.4.3 shows all except a Mitsumi CD writer. Is there a known problem ? Is it just me ?
