Hi Tejun, My NVIDIA SATA controller is having some problems with smartctl on 2.6.18 (+ the previously mentioned sata_nv patch). If I try to enable Attribute Autosafe (smartctl -S on) or Automatic Offline (smartctl -o on), the controller craps out (but recovers). Executing the same command on an identical disk connected to a SiI3132 works fine. Other SMART stuff (reading attributes, running self-tests) seems to be behaving just fine. -jim ### sata_nv controller (CK804): # smartctl -data -S on /dev/disk/by-path/pci-0000:00:07.0-scsi-0:0:0:0 smartctl version 5.36 [x86_64-unknown-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF ENABLE/DISABLE COMMANDS SECTION === Error SMART Enable Auto-save failed: Input/output error Smartctl: SMART Enable Attribute Autosave Failed.
