From 9e4d4a5d71d673901d9c1df5146ce545c2cc0cc0 Mon Sep 17 00:00:00 2001 From: "Salyzyn, Mark" Date: Tue, 1 May 2007 11:43:06 -0400 Subject: [PATCH] [SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllers The kexec patch introduced a superfluous (and otherwise inert) reset of some adapters. The register can have a hardware default value that has zeros for the undefined interrupts. This patch refines the test of the interrupt enable register to focus on only the interrupts that affect the driver in order to detect if an incomplete shutdown of the Adapter had occurred (kdump).
