Yamaha CRW6416 not recognized

Tue Sep 12 10:08:06 PDT 2000

I have a Red Hat Linux 6.2 system, running the stock 2.2.16-3 kernel from 
Red Hat's update site.  This system has an Adaptec 2940 Ultra Wide adapter 
with 3 internal scsi disk drives and 3 external devices in a scsi enclosure 
cabinet: a 4mm DDS3 tape drive, a TR4 tape drive, and a Yamaha CRW6416S 
CD-RW drive (id 4).

When the system boots, the Adaptec BIOS detects all 6 devices.  However, 
the Linux aic7xxx driver does not see the Yamaha CRW6416S CD-RW drive. 

I've searched through the list archives and the web for reports of this 
type of problem.  The closest thing I found was the "probe all LUNs" 
problem in the kernel that shipped with Red Hat 6.0.  The fix there was 
to update to a kernel wherein the "PROBE ALL LUNS" option is disabled. 
For example, the kernel that shipped with Red Hat 6.1.

Below, I've appended the output from /proc/scsi/scsi and 
/proc/scsi/aic7xxx/0. 

Does anyone have any suggestions?  TIA.
