[Borislav Petkov]

Hi Bart,

i'm getting the following when the S.M.A.R.T. daemon starts during boot (verbose
printk added by me):

...

and this is "caused" by
ide-use-correct-data-phase-for-smart-read-data-log-in-ide_cmd_ioctl.patch. This
happens, IMHO, because when you do ATA_CMD_SMART from userspace ioctl, one of
the cases is that the tf->feature flags have values which are inconsistent with
the ATA/ATAPI v.7 spec (6.54.5 SMART READ DATA):

"If the device does not support this command, if SMART is disabled, or if the
values in the Features, LBA Mid, or LBA High registers are invalid, the device
shall return command aborted."

For example this one:

[   30.499581] ide_cmd_ioctl: args[0]: 0xb0, args[1]: 0x1, args[2]: 0xd1 args[3]: 0x1
[   30.516111] hda: task_no_data_intr: status=0x58 { DriveReady SeekComplete DataRequest }
[   30.516387] ide: failed opcode was: 0xb0

However, the case with the SMART_READ_LOG looks correct above: args[2] = 0xd5
which is the tf->feature flag, cmd = 0xb0 (ATA_CMD_SMART). This one fails too, though.
