The problem is that the code for powertop always suggests catting to host0 if it finds something other than min_power in ANY of /sys/class/scsi_host/host*/link_power_management_policy
My host0/... has min_power, but host1/... et al have max_performance, so powertop complains about host0 because it's a hardcoded string.
