Subject:   Problem with SCSI CD's and "skip" messages

I have the following problem.  I have a PCI SCSI Controller using the NCR
driver to drive seven double-speed CD-ROM drives.  Due to dust on the lens
or something, sometimes the kernel reports skips, like so:

Sep 24 16:00:16 server /kernel: ncr0: timeout ccb=f066d000 (skip)

My problem with this is that after a few of these messags, the machine
suddenly decides it can't do ANY disk I/O, the main hard disk on an IDE
controller included.  This presents a problem since files that are used
all over the network are stored on that IDE drive, resulting in timeouts
galore.

Why would timeouts on a SCSI controller stop the IDE drive?  The SCSI is
on a physically different controller.  (IDE is built-iin to the
motherboard). 

Is there anything I can do?  I'm using 2.2.2-RELEASE on this machine (am
thinking about 2.2-STABLE RSN...)
