From e08afeb7e69f45e4ab9fbb8530fe433484b96606 Mon Sep 17 00:00:00 2001 From: Brian King Date: Tue, 23 Jun 2009 17:14:01 -0500 Subject: [SCSI] ibmvscsi: Fix module load hang Fixes a regression seen in the ibmvscsi driver when using the VSCSI server in SLES 9 and SLES 10. The VSCSI server in these releases has a bug in it in which it does not send responses to unknown MADs. Check the OS Type field in the adapter info response and do not send these unsupported commands when talking to an older server.
