I suggest that you check to see if any scsi reservations exist on your
disk. Eventhough you disbled scsi_reserve, the reservations could stll
exist and cause problems.

sg_persist -i -r <device>

This will show you any existing reservations. If any exist, they can
be cleared using this command:

sg_persist -o -C -K <key> <device>

where key is the reservation key listed by running the first command.
