           Summary: sata_svw failed to kdump with pending IOs
           Product: SCSI Drivers
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline

         Component: Other
        AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx
        ReportedBy: caiqian@xxxxxxxxxx
        Regression: No


After running IO-intensive workloads in the normal kernel, manually
triggering kdump ends up hanging below. Kernel version - 3.2.7.
