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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/305895 Title: SATA ALPM link power management setting not detected properly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
