ARC-1882 with 1 disk attached works if I create a pass through disk with
the controller in RAID mode, if I switch to JBOD mode, disk is never
detected.
Even though there is no RAID volume configured, kernel still waits with
the following messages on reboot
arcmsr0: timeout waiting to stop bg rebuild
arcmsr0: timeout waiting to flush cache
dmesg from a patched kernel with controller configured with a
passthrough disk in RAID mode:
