I have a machine here that prints "kernel: ide: failed opcode was: 0xb0" every time smartd is started, I haven't seen it before on any of my SCSi disks, and I can't find any real reference to it either..
The IDE opcodes/commands can be found in the ATA specs - I don't have a URL handy. You wouldn't see this for any SCSI drive, as they wouldn't be using the IDE interface - but as the smartmontools were originally only for IDE drives, perhaps it is some left over. According to some code I saw at smrtmontools.sf.net, the 0xB0 command is for "SMART ENABLE/DISABLE ATTRIBUTE AUTOSAVE ":
[Note: the second of these commands is listed as "Obsolete" in the ATA specifications. It was originally defined in SFF-8035i. Most vendors (IBM/Hitachi, Maxtor, Samsung, WD, among others) still implement it for backwards compatibility.]
Maybe you can get rid of it by only running smartd on your SCSI drives. /Per Jessen, Zürich
