+Subject: scsi: aacraid: Fix INTx/MSI-x issue with older controllers
+
+commit 78cbccd3bd68 ("aacraid: Fix for KDUMP driver hang")
+
+caused a problem on older controllers which do not support MSI-x (namely
+ASR3405,ASR3805). This patch conditionalizes the previous patch to
+controllers which support MSI-x
