Subject: [RHEL5.0 PPC PATCH] RHBZ# 211304: RIT104437- IBMVSCSI does not
 correctly reenable the CRQ.


BRHBZ#:
------
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211304

Description:
------------
The attached one line changec to drivers/scsi/ibmvscsi/ibmvscsi.c corrects 
a problem created when integrating a mainline patch.   Without this 
update, parition Migration is unable to recognize disks after a migration.

RHEL Version Found:
-------------------
RHEL 5.0 beta

Upstream Status:
----------------
The patch has been accepted into the scsi rc fixes tree, it should make it 
in 2.6.19-rc3. Commit to James Bottomley tree:
http://www.kernel.org/git/?p=linux/kernel/git/jejb/scsi-rc-fixes-2.6.git;a=commit;h=ebe921d2f27cccd5225bb01bf4f532ca8bcca582

Test Status:
------------
To reproduce this failure, perform a Active Partition Migration.  This 
patch builds cleanly against kernel-2.6.18-1.2727.el5.src.rpm.
