The command 'smartctl -a /dev/sdb' fails with 2.6.22-rc4 kernel. The disk /dev/sdb is a SATA disk. The command does work still with a real SCSI disk. The computer has Athlon64 X2 and it is running x86_64 SMP kernel. The chipset is Nvidia CK804 and the sata_nv driver is used. The following output from 'smartctl -a -r ioctl,1 /dev/sdb' tells the disk details and shows where the regression is: ----- smartctl version 5.38 [x86_64-suse-linux-gnu] Copyright (C) 2002-7 Bruce Allen Home page is http://smartmontools.sourceforge.net/ [inquiry: 12 00 00 00 24 00 ] scsi_status=0x0, host_status=0x0, driver_status=0x0 info=0x0 duration=0 milliseconds resid=0 status=0x0 [ata pass-through(16): 85 08 0e 00 00 00 01 00 00 00 00 00 00 00 ec 00 ] scsi_status=0x0, host_status=0x0, driver_status=0x0 info=0x0 duration=4 milliseconds resid=0 status=0x0 Detected SAT interface, switch to device type 'sat' REPORT-IOCTL: DeviceFD=3 Command=IDENTIFY DEVICE [ata pass-through(16): 85 08 0e 00 00 00 01 00 00 00 00 00 00 00 ec 00 ] scsi_status=0x0, host_status=0x0, driver_status=0x0 info=0x0 duration=0 milliseconds resid=0 status=0x0 REPORT-IOCTL: DeviceFD=3 Command=IDENTIFY DEVICE returned 0 === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.10 family Device Model: ST3320620AS Serial Number: 9QF22KAP Firmware Version: 3.AAJ User Capacity: 320,072,933,376 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Sun Jun 10 10:47:30 2007 EEST SMART support is: Available - device has SMART capability.
