Description of problem:
Changes were recently accepted in kernel.org's 2.6.14 kernel to add reference counting to the SCSI tape driver. Without these changes, surprise removal of the HBA connected to a tape drive is problematic. It would be great if Red Hat could backport this functionality.

Discussion of these changes is here:
http://marc.theaimsgroup.com/?l=linux-scsi&m=112058392531041&w=2

I'll try to attach patches against your U2 sources.

Version-Release number of selected component (if applicable):
kernel-smp-2.6.9-17.EL

How reproducible:
Always

A slightly different but functionally equivalent version of these changes has
already been incorporated in the RHEL4 kernel.  Closing this bug out.
