From e5a44df85e8d78e5c2d3d2e4f59b460905691e2f Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Fri, 11 Nov 2011 11:14:23 -0500 Subject: [PATCH] [SCSI] hpsa: Disable ASPM The Windows driver .inf disables ASPM on hpsa devices. Do the same because the selection of a non default ASPM policy can cause the device to hang.
